How does the efan conversion work
So im trying to figure out my over heating. Ive got a 2001 2500hd ive converted to efans the nelson performance harness. Does high speed only come on if i have the a/c on? Looks like it will only come on if a/c is on and low speed fan is on? Because i just have the one pcm trigger. And will never go high speed only because of temp?

how hard would it be for me to modify this harness? is it the same except the a/c wire gets hooked to hot and the ground for that relay is now for second pcm pin?
