So I had another post saying that I am about to install HIDs into my 2013 LTZ. I don't want to drive around all day with HIDs on. I know there's harnesses you can install so they don't flicker and what not. Is there anyway I can wire/change settings to make my fog lights my DRL instead of my normal for lights. I know there has to be someone here who has done this or researched the topic.
I have the stock fog lights. I'm not installing fog lights or those LED fog lights. Also I know I can just turn off my headlights but I don't want to have to do that every time I get in the car.
Some have talked about removing the spring from the light switch so when you move it to "off", it stays "off". Of course, you lose the automatic lights feature.
I've been wanting to add LED DRLs to my car, but when I do that, I want to make it so the headlights are no longer the DRL. None of the kits I've looked at will do that. But I think I've figured a way - simply install a relay such that the headlight line passes though the NO contacts and wire the coil to the parking lights. (Headlight DRL - no parking light, relay open. Parking light - relay closed, but no power on the headlight line. Headlights - power on headlights AND parking light.) I would add a diode across the coil so the relay spike doesn't go back to the BCM.
I am also very interested in this because I just installed HIDs and the DRL really messes things up. Occasionally, the driver side HID stays on when DRL are supposed to be and then when it gets dark, only the driver side comes/stays on.
My questions is, if the 2015 have LED DRLs, how is the wiring different? Is it something that can be easily transfered to the other years (mine is a 2013)?. Is it an additional relay or something like that? I'm sorry I'm not very knowledgeable when it comes to electronics/wiring but I can follow instructions
I have ebay LED fog lights that I'd like to use as DRLs.

You might try my suggestion of adding a relay that prevents the headlights from turning on unless the parking lights are on. This will remove the DRL function.
I'd lay money on the DRLs being powered from the BCM (just like most of the other lights), and the BCM has a program for it. It would be nice to get a hold of a 2015 manual and see how it's done, but I don't have much hope it can be transferred to 2011-2014. Even if those pins are available on our BCM, we'd probably need a modified flash update to do it.
You could install a drl relay for the fog lights, then use the parking lights for the hid relay trigger wire. But you would never have control of your fog lights if that's ok.

Anybody happen to have a detailed wiring diagram of those circuits? The challenge, as far as I understand, is to ensure that the new circuit fools the blown light / circuit failure indications.
I have both the dimmed DRL headlight and the LED's in the foglight location. I hope to come up with a means of disabling the dimmed headlights and include the corner lamps along with my LEDS as DRL's I am convinced that it will look better and save some energy and bulbs. I also think of it as added feature for those fine poeple that feel that 120 plus in a foggy 100 km/h zone is safe and they suddenly see a grey car with no lights on at all on the rear.
Just incase anybody is wondering I don't allow the automatic lighting system to make all of my lighting decisions, but it will to have those corner lamps as always on by default.
Not much to see. With the exception of the high beams which are controlled by a relay, most all other lights are controlled by an individual connection to the BCM. Individual as in each filament/bulb has it's own connection. (That includes each individual corner light.) I can't remember if fogs are on relay or not.

Most likely the new LED DRLs on the 2015 cruze is going to be a PWM current and voltage control out of the BCM, LEDs have to have a controlled supply because they drift in current draw and light output as they warm up, most LED power supplies are a constant current design, knowing what GM has been using I'd say the new LEDs are PWM controlled, I doubt you could just transfer your aftermarket LEDs to the 2015 cruze BCM, but they could easily be run off the controller they likely came with, all leds are not created equal and have different optimum drive parameters, some lights series or parallel the individual LEDs and sometimes both ways !
Should work with a load resistor on the upper contact, I'd add a series diode on the relay besides the spike diode
I'm pretty sure the BCM uses a current sense circuit that if triggered the micro quits trying to turn the load on if excessive, I'm pretty sure the engineers tried to allow for a shorting bulb filament so the window of triggering is probably large, that said I still wouldn't mess with the BCM light output ports much due to the cost of the BCM and having to pay to have a new one programed, been my experience that the small devices used in todays electronics can and do short at the least little overload, most engineers use just some extra copper on the circuit board for heat sinking and the devices are tiny and cannot dissipate any overload past their rating--
I'd like to keep automatic lights if possible and disable drl. Otherwise disable drl and automatic lights altogether. Ideally I'd like my LED fogs to be drl
So in that case you don't have anything connected to the plug for the low beams, right? Does this not send anote error code about the bulbs being out/dead?
Have been looking into this kind of thing myself (except using led halos as drl) and am going to be using a single pole double throw relay. Basically its normally closed on one side and when power is applied it switches over to the other. Going to use the low beam wire as my single pole and have the normally closed pin as the halo and switched pin as my signal to my hid harness. Going to be using the parking lights to fire the coil and switch over. This was the led will be on as a drl then when the parks cut on the led will go off and headlights on. Easy as pie lol. Can do a little writeup if youd like as i will be doing this tonight actually.
You know im glad you said that. Guy at the parts store was new and not so good lol. Threw me off. Walked out with one that had a resistor instead of the diode. After reading i can see how the resistor will still work but think id rather be safe and get one with the diode
Sorry to resurrect an old thread but I have my lights figured out how I want them and I just wanted to post an update.
Thought I had never wired relay before, I read up on it and went ahead purchased some.
I bought this (HID Conversion Kit Wire | HID Relay Kit | HID H7 Relay Harness Wiring) for my HID conversion and 2 of this (5-Pin 12V 40A SPDT Relay Socket Wire Car Fog Light DRL Lamps) for both the HIDs and my LED DRLs. Using the diagram from the 6th post on this page (relay for 2 triggers and 1 output), I wired HID relay harness together with a regular relay so that it requires 2 inputs (one from the parking lights and another from the low beams) to light up the HIDs. This way I keep the automatics lights, keep the ability to turn on only the parking lights, and the car's DRL will not turn on my HIDs during the daytime. For the LED DRLs, I used the second regular relay, drawing the input signal from the #48 fuse in the fuse box (AC or radiator fan, I think) since it comes on and stays on as far as the engine is running. I used one of these add-a-fuse for that.
Hopefully this helps someone interested in it. Sorry about the crappy phone camera video.
Hi guys we make a plug and play harness for this mod in the camaro, we have a Cruze here at the shop, we did a harness like this, but without moving the power to the fogs, i will make one that way and post it up soon.
If you have fog to start, with the right wiring you can move the DRL to the fog in the day time with switch in auto, then at night they go back to normal and you control the fogs as before, it can all be done with with the right wiring.
