I am trying to install an Alpine cd player in my 93 Vr4. I cant get it to work though. i have tested the wires, and the red power wire IS hot, but there are some wires that went into the factory stereo that I dont know what they do. There is a large plug that has the power, ground, speakers,etc,. There is a banana plug for the antenae, there is a small plug that has two yellow wires that I now think are for the factory amp(that I dont have)and then there is a small banana plug that is connected to a grey wire. I did an experiment to see what was necessary.
I plugged in the main plug into my factory stereo, and I plugged in the antenae wire. Power would not come on. I plugged in the "amp" pug...nothing happend. So I unplugged the "amp" wire and plugged in the small banana plug. Wallah! POWER! Okay..problem solved right? WRONG! What is this small banana plug and how do I wire it into my wiring harness for the Alpine? I dont think it is a ground wire because I tried touching the ground wire from my harness to it and still nothing happend. HELP!!!
