I just put an aftermarket CD/MP3 reader in my 93 240SX hatchback, and couldn't for the life of me get the damn thing to make any noise. the eq was jumping around (on the CD player) and the it was remembering the time, so I knew it had ignition and constant power, as well as it was actually reading the CD. after six hours of desperate experimenting I decided to try some very risky procedures...ya know, touching random leftover wires to random other leftover wires. Hoping I wouldn't blow up my car, but at the same time not giving a shit, I touched a blue and white wire (I thought it was another power antenea wire) to the blue wire on my wiring adapter kit...and boom, the radio blares to life! I checked the wiring guide and the blue wire reads "factory amplifier"
