Rob, 

 

  How GM has this configured on the 3rdgen F-bodies, is the fanswitch 
controls the ground signal to the relay.

 

  The relay will have 12volts on it at all times, the other side 
(ground of the coil) goes to the fanswitch.  When temp hits the turn on 
point, the switch's resistance is lowered enough to effectively ground the 
relay, and turn it "on".

 

  I forget (but can look in my schematics book) if the relay passes 
the ground or the voltage to the fan, but either would work.

I have a Painless 18 circuit wiring harness and have had no problems with 
it 

except that it has not so good instructions for hooking up a fan relay and 


switch. I have a 350 in my truck and picked up a fan switch for a early to 


late 80s camaro/firebird. Im sure many of you have done this so if you 
could 

give me some info it would be appreciated.

 

Thanks

Rob
