Question:

97 geo tracker wiring stereo?

I have two white wires left...one is a speaker wire and the other is the constant 12v wire and I don't know which is which. They are the same thickness so unless one of you guys know I'm pretty much screwed here. Also, I have a black ground wire sticking out of the wiring harness and the ground wire from my stereo harness doesn't look like they should attach to each other. This is my first install and I've got everything else hooked up. Just need some pointers.

Answer:

How would we be able to tell you the difference between two identical white wires? Use the one on the left? Use a volt meter, and find out which wire has voltage on it. A speaker wire won't test with voltage, a constant power wire will. You can always connect the head unit's ground wire to a metal point on the sub-dash. Edit: if you don't want to use the factory ground wire, it doesn't really need to be connected to anything. I suppose you could attach it to the same spot you connect the head unit's ground wire.
