Parts you will need:
All are GM part numbers.

Switch pn: 15853223
Bezel pn: 15853222
Connector pn: 12102900
(be warned the connector was 3x the cost of the switch and is not needed.)



Find a location suitable for you to install the switch. I chose the glovebox because it is hidden and close to the BCM.

I had to modify the switch because I didn’t want to spend extra on a connector. I trimmed the back of the switch to gain access to the terminals.

The terminals you will want to use are A and C. I soldered the wires directly to the terminals. The other two terminals can be used for lighting the switch if you want. It will light red as I sourced the switch from an 07 pontiac G6.

Drill a hole large enough for the trim bezel.The retention tabs on the bezel should sit behind the panel without intruding into the center. There is a raised portion on the bezel that indicates the top.

Feed your wires and switch through. Push the switch in to place, it should click and be flush. It has a very specific location to make it sit flush.

Remove the trim panel on the left of the passenger footwell to gain access to the bcm.The connector is pink, the wire is yellow with a dark blue tracer. I used a scotchlock (even though I detest them) to connect one side of the switch. It does not matter which terminal on the switch you connect to the signal wire on the BCM.

Run the other wire to a suitable ground. Your switch should pop the trunk like the button on the trunk when it is connected correctly.

Re-install any panels you removed and you are done.

Amazing they didn't just do this from the factory. I will have to do this once it warms up outside.

Fantastic! Thanks for sharing!!!

This modification just taps into the rear trunk release signal and grounds it the same as the rear switch does.

Great DIY thread. I use a similar method to operate the garage door opener from a dash button and "hide" the opener itself up behind the dash to keep it from being stolen. It also looks neater. The US Cruze doesn't have any blank panels to mount a switch in, so the glove box mount is slick.

We're on the same track, Jim... I was thinking about the "dummy" button that mirrors the eject button on the CD player slot. Hmmm.

WRT to the garage opener, I have mine velcro'd indise the map pocket on the driver's door. Easy to reach and out of sight.

FWIW, here's the DIY write up I did for Black Betty. I don't know why it had such a large font in the OP and I never got around to changing it. Our P5 has the same setup. These cars always seem to have one or two blanks from options or other country production requirement.

Are those GM Part numbers?

Are those GM Part numbers?

Yes, I obtained them from my parts department at work.

 

[neirfin]

will this allow the trunk to open even when the car is running? one of my biggest gripes about this car... no trunk button.

 

[JerTM]

Yes it does.

 

[neirfin]

thats so awesome im totally doing this.

Ha, April fools version 2.0: wire the same switch hidden a bit better, take to dealer, ask them to fix the trunk that pops every time you slam the glove box shut.

Very nice!
I really would like to do this as I find the outside switch gets frozen up in the winter often.
Wonder if you have a P/N for the connector as well by any chance?

 

[JerTM]

I don't at the moment. I will post it tomorrow for those that are interested.

This is a cool mod. One that I seriously want to do.

 

[JerTM]

Updated the op with the connector pn. But get ready, cause it's 3x the cost of the switch and bezel.

Thanks! Ordered the parts today.
The connector was just a bit more than double the cost of the switch! lol

Great write up! I actually done this today. Took about an hour and $10.00. I didn't use the GM parts, picked up a momentary push button switch at O'reilly's Auto Parts and a pack of wire connectors, used some left over t-stat wire for the run. I put mine down by the fuse box, to lazy to bend over and open the glove box!

Check it out!

Very nice mod, and would solve a pet peeve of mine as I have to go through security checkpoints that require me to pop the trunk.

Well done!
