When I pull the ECM. Blue cover so I inserted into pin 42 with green wire. And inserted into pin 33 for blue wire in same blue cover. Fans still not
Work anything. Turn ac on and not turn fan. Over 210 temp won't do anything. I readed over and over on the instruction. They say connector 2 which other green cover that mean I need insert pin 33 for blue wire? If
It is that one. I have to go back and re-do pin. Let me know.

The Green wire goes to pin 42 in the blue covered connector, this is fan 1.
The Blue wire goes to pin 33 in the green covered connector, this is fan 2.
And you also have to have a tuner or someone with the software (hp tuners, efi live, etc) enable the fans in the pcm

If you have not had the truck tuned with HP or EFILive it will not turn the fans on as the bits in the PCM are not enabled to do so. The truck needs tuning changes to make the fans work. They will not ever come on with a stock 2004 clutch fan trucks tune!
