I have been trying to wire up a new stereo for my 2005 express, and I have already cut the factory harness (oops). The problem I have is that I cannot find out where the accessory wire is, and consequently the new unit will not shut off with the car because it's only wired to the 12v constant. I gave tried to use a multimeter to find the accesory wire by having the key in the on position and seeing which wire reads 12v, but the only wire I get a reading for is the 12v constant wire. Anybody know which wire is the accessory wire? Or whether there even is one?
