Hi again folks. Could anyone tell me witch pins I’ll use on a 03 ecu Truck/Tahoe for enabling the fan 1 and 2? I do have the diagram for 02 mod, and it’s not the same. I have tried that. Pin 42 and 33. I have programmed it to serial fans with two outputs.
Thanx for all help.
Reg Chris.

 

i just put the Nelson harness on my e fans and they it only tapped into pin 42, that's it. why not set it to two auxilary fans, that works for mine?
