I have a complete oem set up the fans,rad,and wiring harness from a 06 silverado I really need help on how to wire everything. There a black wire that looks cut but don't know if it got cut accidentally or ground clamps got cut off.


There is a small plug idk if that is were u get the trigger wires from or the ones that go to the pcm. And if not how could i wire it so i can control it of wen to come on and off. Any help. Preciated

 

I moved your post to a more appropriate section. See diaghram below.

 

That small plug should be the one the wires from the pcm tie into, that black wire looks like the ground!!!

 

.....

 

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.

 

03up are literally plug tune and play...after you run the harness and connect everything of course....

 

So both the green and blue wire go into the same pin? And which pin#?
