Buck_ss03 Posted July 27, 2014 Report Share Posted July 27, 2014 So I bought OEM electric fans from a buddy of mine he said they came of a wrecked 2005 silverado 1500. In the picture whoever had them before him made there own ground with a thick wire on the fuse box. I'm hoping that's fine. My question is the plug with the blue and green wire. Where exactly does this go in my 2003 silverado ss. I know that I have to put blue in pin 42 but the green I have no idea where it would go??? So if anyone's done this install with OEM E-fans please give me answers on how to install without buying a harness would rather try to keep it as if it was straight out of factory. Thanks guys Quote Link to comment Share on other sites More sharing options...
