I want to put OEM efans from a 05+ Silverado In my 03 Silverado I already put the 34in radiator looking for best place to get fans and harness already looked at local junk yards didn't have anything I could use

 

Black Bear and Nelson Performance Nelson Performance both sell an add on fan harness. They can also turn the fan option on in your PCM

If you have the 34in radiator you can either buy the OEM style E-fans from Dorman through a parts store or on Ebay. There is also used ones that pop up from time to time.

 

I looked on black bears site and they didn't have any but I'll check out Nelson thanks

 

Make sure you get the harness that adds 2 wires to the PCM, not 1 wire to the PCM and 1 wire to the A/C clutch.

 

Well they used to sell them. Since they changed the site around I can't find them any more.

Looks like Nelson still builds them.

 

Yea I found them on Nelson's site and the have the harness for PCM only control

 

Ls1fans makes the harnesses. If i didnt get an oem harness i would have used them. Nelson harness was known for blown relays.

 

Just looked at the ls1fans site I'm going to give them a try

 

They were the ones who built the blackbear harnesses, to my knowledge. I had one of them previously. Very good quality.
