Has there been a stock diagram posted? I saw the one for adding a manual switch, but I want to see what it looks like stock. I just bought the car, 1988 IROC, and the fans are not coming on at all. Someone messed with the wiring , specifically an orange one by the battery, I'm not sure what they were doing, maybe trying to get them both to run. The fans won't come on with the air cond. on either. The radiator is new, and it runs good on the highway, but as soon as you stop it gets hot quick.

 

as you can see. all you gotta do is take away the "wire manual fan switch here" and you have the factory wiring..

if u need any more help let us know.
