Trunk release wiring info needed - want to add release on trunk lid

[mjs001]

That works like the one on my BMW did - push the button above the license plate and as long as the car is unlocked, the trunk opens. If the car is locked, the button does nothing. Is there any body control output on this car that is energized when the car is unlocked but not when the car is locked?

That way I can toss my luggage into the trunk while the keys are still in the ignition.

I believe it has to be unlocked to open the fuel door. Check there.

hmmm this is a good idea, please keep us in the loop, and take lots of pictures during your install

The unlock is in the glove box. The doors don't have to be locked/unlocked for that circuit to operate.

It looks like if you do use the fuel door actuator wiring you will need to wire in a relay because it gets it voltage from the BCM.
Now thinking about it I don't think the BCM will supply constant voltage to the actuator while the door is unlocked so that might not work either.

Looks like I'll have to run a wire from the glovebox switch. I checked, and the glovebox switch behaves the way I want - it opens the trunk only when the car is unlocked, whether the ignition is on or off. Hope to have the chance to do a test wiring this weekend.

Greg - you're right. The fuel door latch works just like one of the power door locks. Pulse sent to the unit, not continuous voltage.

This is an awesome idea. Please keep us posted.

That's a great idea. My mother in law just took delivery of a 2010 GMC Terrain and it has a cool rubberized weatherproof "button" under where the license plate frame is. Not sure if you can research/source that part, but that could potentially provide the button functionality at the trunk area, as well as be weatherproof already.

This is a great project for sure.

I always liked how BMWs and others have this feature
