now dont you think your overreacting just a little bit?

 

ok, here's whats been built so far......





The three black leads are as follows....
Far left - PCM C1 #42
Middle - PCM C2 #33
Far right - Ground for harness

Red are as follows....
Far left - Left fan + side
Huge Middle - Battery +
Right - Right fan + side
Far right - Left fan - side.

The right fan - side will obviously go to ground. This is exactly as GM wires the fans in the trucks...check it out....



It pays to work for GM................

The only thing I am changing is the fuse locations....instead of 3 seperate ones, I will have one 40 amp fast blow on the batt + side. Or I could go through and re-pin the connectors on the relays for more wire length if I am feeling bored.....but probably wont.

 

oh yeah..I plan on making a nice little cover for the mess of wiring I have going....it should look pretty OE like.

 

i had a similar problem about 2 weeks ago, except it wasn't my relay that blew, it was my inline fuse. just melted in it's place...changed it out and haven't had a prob...

 

I like it! good job brother, let me know how it works out

 

Has anyone else tried to wire Efans this way? Doesn't HpTuners/EFI live have the option for 1 Aux Fan or 2 Fans?

I found this on EFI Live Forum

I would really like to know how this is going. Updates???

 

Yes HPTuners has the 2 fan option, although I'm not sure every PCM will activate it. The option is there for my application however so I'm looking into a 2 pin activation setup.

 

same here. going for the two pin, if no go, then one pin it is....

 

whats your ETC on this?

 

the problem with the two pin setup is figuring in your fans to come on with the A/C. this could be figured in with a tap to the a/c turn on, blocking diode and another relay to switch polarity (a/c lead is positive)
