I got your message late last night btw. I'll see if I can find my pics. It may be a Haltech thing but I cant say. But dont those have their own inputs you can run the fan to directly and then just control it off there via temp? I believe AEM has this if I remember right from a local guys Z I helped with. Been years so its all fuzzy.
May be the way you have it wired as well without seeing it I cant say. I dont know what pins and such it uses. I just traced and used the wires that went to the stock relays.
