so yesterday i was tyring to install my cd player and when i opened up i found 2 wires for antenna, i think? what the hell is this?!?! the one which has the female end, does it still get used? also when id plug all the harnesses in my warning beeper for doors and such would just start going iff without key in ignition. why would this happen? i couldnt get any sound out of it either. one more guestion, where the hell is the ground wire. its a 2nd gen. btw.
