i have an 88 pontiac trans am i bought without a radio in it im trying to hookup a cd player in it now....could sum1 tell me the color coding for the wires??

 

Generally speaking:

Red = Ignition wire for main power
Yellow = Battery wire for memory
Blue = Accessory wire for amps and/or EQ
Black = Ground
White = Power antenna or cellular phone

Any other colors are probably for speakers, usually two of the same color with one wire having a stripe assigning polarity

------------------
92 Camaro RS LO3, 5-spd, T-tops
Performance:
SLP 1 3/4" Headers (Coated by Paul Barry Motorsports), Flowmaster Catback Exhaust, Fastchip Performance PROM, Centerforce Dual Friction Clutch, Xact 8mm wires, Open Air Element w/K&N Filter, Z28 Grille w/aftmkt fog lamps
Electronics:
Alpine 8030 Alarm System, Valentine One Radar Detector (How did I ever drive without one?), Pioneer DEH 7450 Head Unit w/6-pack CD changer, Pioneer DEQ 7600 Sound Processor, 2 Kenwood KAC-846 Amps powering 2 12" Pro Red subs, 2 Pioneer 6x9 and 2 MTX 4x6 speakers.
NEXT UP: TBI mods, Edelbrock performer intake

 

On my '88 GTA, red is for the power antenna relay and orange is ignition wire for main power. I'm trying to find out how to power the stock subwoofer amp. Sure hope I have an unused blue wire!

If you are looking at the stock wires, then maybe you should consider getting a wiring harness adapter. The colors I mentioned are for aftermarket components.
