88 iroc z dual fan hardwired?
Picked up a 88 iroc z 305 tpi With dual fans
The HD fan is on with the key but the relay and power wire after driving are rather warm. I looked at the wiring diagram and it looks like a power wire off battery goes to relays and fans. So there must be a jumper wire to a keyed accessory or something turning the fan on with the key. Is there a location to do this I can't see?
Also the fan on PS is controlled by the switch between 6-8 cylinders and the DS fan switch is up under front of intake ? Or vice versa ?

Re: 88 iroc z dual fan hardwired?
I can only help with this part, as I've been messing around with my setup as well this week. The primary fan (drivers side) is controlled by the ECM, the secondary is controlled by the sensor found between 6 & 8.
