This thread describes how I made a wiring harness to install a MyLink radio into a car that had the base green screen radio. I decided to write this post as "how I" instead of "how to" because there are many different ways to do this. I am not going to give every single detail about how I did it. You will need to use a little of your own imagination and creativity.

To create a wiring harness, you will need good soldering skills and you will need to have some experience with wiring and crimping tiny connectors.

When I built my harness, I decided that I wanted to be able to switch back to the original radio if I ever felt like it. This means that I needed more connectors so that the original wiring would remain intact. It is possible to do this project permanently, and that could possibly save money on connectors and time on building the harness.

To start, this is the wiring diagram I used.

A couple notes on the diagram:
1- I have the Pioneer premium sound system, and Pin 43 on the X1 connector is used as the remote enable signal for both the touch screen and the amplifier in the trunk.
2- The body harness on my car has all of the wiring for the backup camera. I just needed to add the wiring between the radio and the body harness and between the camera and the body harness.
3- The power for the radio controls and the touch screen both connect to the same wiring in the dash harness and both connect to the same fuse.

Twinax Cable. This would be very hard to build, so I purchased it on Amazon with free Prime shipping. This sends the video signal to the touch screen. I paid $20.73. I noticed the price fluctuates a lot on this item.

USB Cable. This would also be very hard to build, so I purchased in on Amazon with free Prime shipping. I paid $15 for this. ACDelco 19118736

I found out that the USB cable from the center console wiring harness can be unplugged behind the Multimedia Player Interface Module (AKA PDIM). The new USB plug for the radio plugged directly into the original USB cable in the center console wiring harness.

Radio X1 Connector
The X1 connector is the large 44 pin connector on the back of the radio. In order to retain the car's original wiring, I used a connector similar to what is used with the PAC Line Out Converter. I only changed the wires that are indicated in the wiring diagram and left the rest alone.

The PAC LOC can be found on Amazon with Prime shipping. This is what I used because the quality seems to be very good.

Here is a similar connector.

Radio X2 Connector
The X2 connector is the smaller 20 pin connector on the back of the radio. The original radio does not have an X2 connector. I purchased this on Mouser for $1.53. There is a small black tab on the bottom of this connector that I needed to cut off in order to make it fit into the radio connector, but otherwise it works perfectly.

8 pins are also required. I purchased 30 pins just in case I screwed up, and they are only about 4 cents each.

Info Display Connector
I had a hard time finding the correct connector and pins for this, so I just bought the ACDelco pigtail on Amazon with free prime shipping. It is ACDelco part number PT2558. I paid $13.96 for this. Amazon usually only has one in stock at a time, so if it's not available, check back a few days later and they may have received another.

Radio Controls Connector
I also had a hard time finding this connector and pins, so I purchased the ACDelco pigtail on Amazon. It is ACDelco part number PT2680. I paid $22.11 for this. Amazon usually only has one in stock at a time, so if it's not available, check back a few days later and they may have received another.

Power and ground for Radio Control and Info Display
Since the power and ground for both of these connectors use the same wires in the dash harness, and they connect to the same fuse, I decided to tap into them by inserting pins into pins 1 and 2 on the original info display connector. I used some leftover pins from the PAC LOC connector that was used for the Radio X1 harness. I built my own connector by inserting the pins into the connector and covering them with hot glue. Then I ran wires to pins 1 and 2 on the new Info Display connector and Radio Controls connector.

Voice Recognition Signal - Telematics Communications (OnStar) Control Module X2 Connector
I needed to add 3 pins to the OnStar X2 connector to add the voice recognition and phone audio signal to the radio. I bought these on Mouser. These are Delphi connectors part number 15445904. They cost about 15 cents each.
http://www.mouser.com/ProductDetail...=sGAEpiMZZMs7eK6h2EBtKiAPJPX6chA8A2XQFMx5WWI=

The X2 connector on the Onstar module has a small plastic square on one side. I used a small screwdriver to pull the square up, and it unlocked the pins so that I could insert the new pins.

The Onstar module is hard to find and get access to add the wires. See the thread below for more information on accessing the Onstar module. After you remove the screws for the module, you can lift it upward a little and it will come out. You can drop the module down below to access the connectors. There are three connectors on the back of the module. One of them is empty. The middle connector is the X2 connector.

Backup Camera
I looked in my car and found out that the body harness has all of the wiring for the camera already there. The only thing I needed was to add wires from the radio to the X200 body harness connector, and wires from the X900 body harness connector to the camera.

X200 body harness connector: I purchased the terminated lead from GM parts site for about $5 each. These are GM part number 13575546. On this harness, pin 6 is camera signal+, Pin 7 is Camera signal-, and pin 18 is camera drain wire. To insert the pins, I needed to remove the gray plastic piece on one side. This unlocks the pins so that I could insert the new pins.

EDIT: I added another post below that explains how to open the X200 connector.

X900 body harness connector. I personally decided to buy the trunk lid harness from a GM parts site (part number 94556229). This cost about $43 plus about $10 for shipping, but it made it super easy to install the rear camera, and it looks like it was installed from the factory. I also bought the full rear chrome bar with the camera in it on ebay. Without this complete harness, I would have needed to run 6 wires from the body harness to the camera.

Auxiliary Input Connector
I also had to run new wires from the Aux input plug in the center console to the X1 connector on the radio. I purchased a used center console wiring harness on eBay. I used the Aux plug and the Aux wires from the used eBay console harness. I cut off the connector on the other end of the used eBay harness and added a generic molex connector that I purchased on eBay. I put the other side of that molex connector on the wires coming from the radio. Then I just plugged it all together.

Wire
For most of the wiring I just purchased some 22 gauge stranded wire from Frys. Cost was about $5. I made the wires for the controls and display the same length as the Twinax cable, which is about 16 inches. It was longer than needed, but it worked ok.

For the shielded wire, I used this. It's a little stiff, but it worked. Cost was $16 with shipping for 25 feet.

Tape
To make everything look nice, I wrapped all of the wiring in fuzzy fleece tape. This also reduces the chance of rattles in the dash. I also covered all of the original connectors in this tape to reduce rattles. This looks identical to the tape used on the wire harnesses in the Cruze. Cost was $4.99.
https://www.amazon.com/gp/product/B00NN6B9R6/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Then I just wired everything together using the wiring diagram.

Total Cost
My total cost for the wiring in the dash (what MVI provides) was about $135. With the camera wiring and trunk harness, the total was about $200.

To reduce this cost further, it would have been possible to save money on the info display and controls connectors. Someone may be able to find these on Mouser, or it could be possible to get them out of a wrecked car. It would also reduce the cost a lot if you added your own wires to the trunk harness.

Before and After:

What a great winter project ..as long as your happy with IT yer good ......

What a great winter project ..as long as your happy with IT yer good ......

It was a fun project. It does add a nice color touch screen and the backup camera. The voice recognition doesn't work that great, and is not important to me. The Pandora and Stitcher apps are nothing special. Pretty much everything else that's important to me is also available on the base radio.

 

[dhpnet]

When I did the upgrade, I did something to the X200 body harness connector that caused the air conditioning to stop working. I didn't notice it until a few months later because I didn't need the AC. I automatically assumed that there was a problem with the refrigerant, and I took it to the dealer. They found that the compressor was not getting a signal and traced it to the X200 connector. The dealer said one of the pins was folded and they fixed it. I have since taken apart the connector again and I don't see any signs of anything being repaired, so maybe it was just not seated correctly.

I did some research on the X200 connector. It is a huge 102 pin connector made by Tyco/AMP. This is where I added wires for the backup camera. When I did the upgrade, I did not look into the proper procedure for disconnecting this connector. I have since learned how to do it correctly. To open the connector, the instructions say to pull the locking lever to the 90 degree position and then slide the male connector out. The locking lever should not be pulled all the way down or the pins may not be aligned correctly when it is put back together (that's what I did).

After removing the male connector, there is a gray bar on one end that is removed to unlock the pins. The pins need to be fully seated before inserting the gray bar back into the connector.

LOL. I think I am probably the only one who has tried this. It's not too hard, but it requires a little patience. And, it's worth it in my opinion.

camera

dphnet, Do you have any other images of the harness and also on the diagram. for the camera you have the wire going from the x2 radio connector to a listed camera connector with pin outs 2,1,4 but on the post its pin 6,7 and 18 on the x200 body harness connector? thank you for the help on this and btw great wright up

I didn't take any other photos of the wiring harness I built. If you have questions about something, just let me know.

I need to update the wiring diagram to show how I installed the camera. I will post an update in a couple minutes.

 

[dhpnet]

UPDATED WIRING DIAGRAM

When I created the wiring diagram. I was planning to run wires all the way to the camera. Eventually, I discovered that the body harness in my car has all of the wiring for the camera, so I changed how I wired it, but didn't update the diagram. I also decided to purchase the complete trunk wiring harness. And, I purchased the complete trunk chrome bar with the camera. I highly recommend doing this instead of adding wiring to the trunk.

Here is my updated diagram. This shows how I ran the wires between the radio and the X200 connector, and the wires for the trunk wiring harness. See my note in another post above that explains what I learned about opening this connector.

dhpnet, thank you. one other question. Where is the x200 body harness connector located?

dhpnet, thank you. one other question. Where is the x200 body harness connector located?

It's almost directly below and slightly behind the hood release latch handle. You have to remove the driver's side sill plate trim.

 

[ugnshadow]

did the install this weekend, long process but well worth it. I have not installed the camera yet but sure that will not be too difficult. I know i did not see the x200 harness going to the trunk have the wiring for the camera. guess i will need to add those. I am having one small problem. the aux port does not work. the usb works though. does the usb have to be removed for the aux to work?

 

[Slumnit]

Hey @dhpnet first of all, great write up on installing everything.. I'm looking to install the backup camera, as my 2015 2LT already has the myLink system installed..

A few questions if thats okay?..

You said you bought "these" GM part number 13575546 (terminated lead) how many did you need to buy? Three? For Pin 6, Pin 7 and Pin 18?

Also in your diagram, Pin 18 (Camera Drain Wire) doesn't connect to anything. It just stops at a "black dot." What/where does the other end of Pin 18 coming from the x200 connector connect/lead to?

What do I need to look for on the "body harness" to see if the camera wiring is already there? specific color wire(s)? or just look where pink 6/7/18 match up with the female-to-male and see if there are wires connected to it already?

Last question; is part ​95407980 the "chrome bar" you got with the camera built in?


Thanks in advance for any answer you can give.. really want to get this done, and your post is the best write up I've seen in my 4 days of researching this.. so really hoping you can help out

Congratulations!!! I hope it's working well. They must have stopped including the camera wiring in the body harness in 2015. Be sure to check the wiring in the X900 connector in the trunk. It might have some of the wiring such as the power and ground.

The USB and Aux port need to be wired directly to the radio. With the old green screen, the USB and Aux first go to a multimedia player interface module, and then to the radio. In the My Link system they need to be wired directly to the radio, bypassing the MPIM (some people also call this the PDIM).

I have never actually used the Aux port, but I did wire it just in case.

 

[dhpnet]

You said you bought "these" GM part number 13575546 (terminated lead) how many did you need to buy? Three? For Pin 6, Pin 7 and Pin 18?

Correct, I bought three of them, for pins 6, 7, and 18.

Also in your diagram, Pin 18 (Camera Drain Wire) doesn't connect to anything. It just stops at a "black dot." What/where does the other end of Pin 18 coming from the x200 connector connect/lead to?

The shield/drain is just cut off right before the radio connector. The service manual call this blunt cut. The black dot represents that it is just cut off. Some other people didn't include the shield/drain wire when they made their harness and said they didn't have any problems. It is supposed to reduce noise in the signal, so I included it.

What do I need to look for on the "body harness" to see if the camera wiring is already there? specific color wire(s)? or just look where pink 6/7/18 match up with the female-to-male and see if there are wires connected to it already?

Look at pins 6, 7, 18 in the X200 harness and you should see pins and wires on the side that goes to the body harness, but no pins or wiring on the side that goes to the instrument panel. And, on the X900 connector in the trunk, you should see pins and wiring for the 6 wires for the camera on the body harness side of the connector, but no pins or wiring on the trunk harness side of the connector.

Last question; is part ​95407980 the "chrome bar" you got with the camera built in?

The listing for the one I purchased on eBay said: "95407980 Rear Decklid Trunk Trim Molding Chrome w/ Camera 2011-15 Chevy Cruze." I just looked for one that said it was original OEM and included the camera. I didn't even look at the part number.

Thanks in advance for any answer you can give.. really want to get this done, and your post is the best write up I've seen in my 4 days of researching this.. so really hoping you can help out

Good luck. I hope it goes quickly and easily. I am still very happy that I took the time to do it. The best advice I can give anyone is to take your time and double check everything.

 

[dhpnet]

Hey @dhpnet first of all, great write up on installing everything.. I'm looking to install the backup camera, as my 2015 2LT already has the myLink system installed.

One more thought. The camera needs to be programmed into the radio software. If your My Link system did not include the camera, then there is a chance that it also does not have the software to run it. I don't know for sure, but it's possible. I don't know how to test for that either.

Thank you, and yes everything seems to be working as it should, even goes to the back up screen when in reverse, just need that camera. but thats a project for a later date. as far as the aux/usb. what green wire are you talking about, there was a usb/micro usb cable that connected to the usb cable going to the usb port. does that cable not include the aux too?

I didn't mention a green wire. The base radio in the Cruze has a green display screen. The old radio with the green display screen requires an interface module to transfer the Aux and USB inputs to the radio. The My Link radio does not need the interface module. The USB and Aux are connected directly to the My Link radio.

I left the interface module in the car so that I wouldn't get any error codes. I ran a new USB cable between the USB plug in the console and the radio. And, I ran new wires between the Aux plug in the center console and the radio. I left the original Aux wires just laying inside the center console. I put tape on the old connector to avoid shorts.

The USB wire does not include the Aux wires. I had to run separate, new wires between the Aux plug in the center console and the radio.

Ok, so just want to make sure im understanding correctly. The aux cable is not part of the usb wiring harness?
