S14 SR20 ECU Fan control
Posted: Thu Apr 14, 2016 3:54 am
I will be wiring some Altima fans and was looking into getting the ECU (69F00) to control them using the feature pack.
I have a couple of questions though. Those ECU pins pull ground right? If so, is it safe to have them drive a 30A Nissan relay that is connected directly to 12v power on the other side? Or should additional resistances be used? I don't want to damage it.
Second question, how do those HI/LOW (LHD/RHD) pinouts work. Is only LHD grounded for LOW then both LHD/RHD grounded for HIGH (or vise versa)? Or is only one pin ever grounded at a time? I hope it's the former.
