I have a 86 Trans am that didnt come with a rear hatch release button. I just wanted to get a lil educated before i try and install one. Maybe some insight or hopefully some pictures of what ill need? Thanks!!

I have thought about adding that option to my 83... was told by a old gm tech that its pretty easy to use the pull down motor/ release from a camaro and just run the wire along the harness for the lights up to the dash and put in a momentary push button...
I'll subscribe to find out more..

I have some stuff i just want pictures and maybe a wiring diagram. I know i can do it i added power door locks to the car. this cant be harder than that. Anyone help me out??

I'm looking to do this as well, have you done it or found anything more about it?

I added mine from a donorcar, that had this button. Basically you will need a solenoid, that is powerful enough to unlock the lock in hatch release, and then run wiring to your button, that provides +12V(solenoid I used got its ground from its body so, no extra wire needed for ground). From the button the wire goes to relay "out" pin. To the relay "in"-pins you'll need a +12v and ground from gear lever(that is needed to prevent hatch opening, when you are in "D") This how it worked for me. When I researched it, then it seemd to me that it is possible to use horn relay but i couldnt tell for sure, I got it from a donorcar. And before you pick your solenoid, check the clearence with the polster. I had to cut the polster to make room for the solenoid from a 84 to fit to the 87 with a pull-down motor. Hope this helps
