I just finished wiring up my f-body efans using the 3-relay drawing from Snakeoiler. Works great, I'm glad to have that back up and running. Only thing different, I used 14awg wire for everything including motor leads but I think it'll be fine. Thanks guys!

Also, instead of connecting to the A/C circuit, I just have that ran to a toggle switch for now. I'll get to that a little later, I have to start gathering parts for my 80 swap...

you can connect it to your PCM and it will work with the AC if your tune is setup right.
