Hi, i recently bought a 1990 Ford Laser Ghia and im trying to hook up my CD Player however i cant define which is the constant power wire from my battery.

i've hooked up the speakers and ground, they were easily definable. but then i had 3 wires that i couldnt put in place. there was a red/black which i presumed was the ACC

i think that the constant power should be yellow. but i dont have a yellow. the 3 wires left are

Red/Black
Green/Yellow
Blue/White (but this also has red or brown on it, which i think some1 painted on when they fiddled with it)

So far my estimations were:

Red/Black: ACC
Green/Yellow: BATT
Blue/White: ILL or DIMM (cause there the only other options left)

But that ^^ didnt work.

If anyone could help me i would totally love you long time. it sucks so hard not listening to music while i drive.
