i have a 03 chevy truck also and it does not have electric fans but i have came across a set of factory electric fans and radiator what would be the best way to wire this up is their factory wires to splice into or anything like that i want to keep it as factory as possible thanks

If you really want to do factory you need to set PCM and at this time I am still unsure of exactly whether all tuners can do this as the factory does on 05 up 1/2 tons. You will need harness # 15912597 which you will separate the E fan harness from. The biggest
problem is 99% of the people doing this are not doing it factory and I understand why
I have been gathering info. for a long time now, and it's just like going to the DMV ask
10 people the same question and you get 10 different answers. I am close to having all
the info. I need and will try to do a complete FACTORY E FAN DIY. The analogy that
comes to mind with what people are calling a factory E Fan install, is when someone says
they have a restored car they are selling. Some people think a paint job means it was
restored, and others a frame off is a restoration, and others everything in between.

 

Looking forward to that! Thanks
