couldnt you do something similar to this but put the constant on 87a vs 87 and put this between the fans and the relay usually there to give a delay (that way the condenser has time to engage before the fans kick).


or....

couldnt you just increase the delay for the ac condenser in the tables and then use 2 pins on the pcm? or can the 99-02 guys not use 2 pcm pins?

i wish someone would. the on/off hi speed with the a/c is getting annoying

the solution might be going with the stock wiring harness

I'm going to examine my mom's stock harness (06 avy) in a bit and see all how it is, and then i'll check her ac delay in her tune and her fan controls. I'd like to replicate stock on mine, it seems to work fine, so ill get back to you guys in a few hours w/ what i find.

Eh, harness is too intertwined w/ everything. I'll check the tune soon, but why does everyone use 1 pin and the ac clutch wire instead of whatever pins the 03+'s use?

Supposedly the '99 - '02 ecms won't turn on the pin for the second fan no matter what the tables say.

I'm planning on dropping an extra pin in just to prove it to myself the next time I have the ecm out. Gotta plumb up the egr position input to my new plx...
