Hey guys, I am in need of the wiring schematic for the '95 f-body dual electric cooling fan system. I have the PCM program from one running my LT1 and don' think I have the fans wired correctly.
A HELM (GM) manual scan or digital photo would be perfect if possible. The best diagrams are the PMC connection schematics.

Thanks

 

Do yourself a HUGE HUGE HUGE favor and go to the Library and check out the factory service manuals for the 95 F-bodys . It is the same manuals the dealer service departments use . It was absolutely invaluble doing my LT1 swap . All the skematics and everything is in there .

FWIW - on my swap , as easy as it seemed , we could never get the pcm to control the fans . The way it was wires I dont see how it possibly couldnt have worked . Sooo , I wired a toggle switch to the fans . Not what I wanted , but it worked .

Thanks, I have the PCM controlling the fans now but they seem to come on too low. I had it re-programmed but not for a 160 thermostat, maybe they threw that in?? I'm only using 2 relays, high and low but the 95 uses 3 relays, so something must be wrong.

 

Do you mean the speed of the fans are to low or they just come on too early . Who programmed the PCM . It is common to turn on the primary fan on at 160* and 2nd fan on at 170* .

 

Come on too early WRT to temperature. The primary fan is almost always on with the coolant temp riding on the thermostat.
Agostino programmed the PCM.
