Hi Guys, I am doing an ls1 conversion into another car and am going through the cooling fan hook up. I assume that the pins C1 42 (BLUE), AND C2 33 (RED) are just switching the earths at the relays? Am I correct?
thanks Mike

Hi Mike,
The ECU does switch an earth for the cooling fans. I can not validate the pins you mentioned yet because I am out of town at the moment. I will be back tommorrow and can check those for you if need be. Though you are runing an older PCM than the one I had. I do have information on the 512mb pinouts though.

Thanks, The pins are correct but are not switching, fan one stays on all the time, fan two will switch on but will not switch off when it gets to the set temp.
Hi Mike,
Are you able to post your tune? I can then compare it to my setup. My setup works well.
Cheers,
