So I have a 95 TSI AWD with a Megasquirt ECU. Before I was using the A/C on switch to control just one fan which wasn't very good, but now I have added another fan and I blow the 20amp fuse when I try to turn on the fans (this makes sense to me). I have an output on the megasquirt that I can use to control the fans, but looking at the factory ecu pin out, I am not quite sure which wires control the relays. I've tried pin 20 before and had no luck getting the fans to turn on when the MS ecu output comes on. Any ideas on what wires I should use?
Additionally, do you know what voltage is supplied to the relays?
Thanks.
