The green and blue wire coming off the relay box are supposed to go to a 2wire connectorbthe other side of which goes to the pcm....c100 in the diagram brick posted
So 2xLS1 it looks like my black wire needs to be tied off together and be joined by a separate ground wire. Because mine onay has one black wire coming from the relays towards the plug. Yours has the same one then one with a ground clamp. I'm installing all this on a 99-00 silverado.
As u can see my black wire is cut. And does anyone know which pins do the the green and blue wire go to. If im installing on a 99. Cuz i know one is used pins 42,33.thanks alot guys
Both to the same pins they came out of you lose the auto recirc feature for the ac, i havent noticed any difference other than when i turn the a/c off i dont have air coming in anymore... Always irritated me....
I'm swapping an 06 harness into my 03. I already have electric fans in the truck. I assume these are the two plugs down by the pcm connectors that my stock harness didn't have? If so I will just get a factory fan harness and be done.
