A little help anyone?
 

We recently got an 88 GMC S15 Jimmy at work, and it has no radio. Now heres the problem - whoever had it before us, cut the factory harness out, so i cant just buy an aftermarket harness to plug in. Does anyone know/know where i can find the factory radio wire colors so i can just splice it directly in? They might be the same as a 3rd gen, who knows.
