Thanks for the replys guys. Im gonna ask my friend Angel, he already wired the fans using the computer how to do it and Ill let you guys know how it works out.

BTW, guess what came in the mail this morning... TNT LS1 wet kit...

Thanks again

Wat color is your GMC so i can keep an Eye on it and catch it on film and post here or something

 

My truck is a 99 Pewter GMC. I haven't taken her to the track yet, but plan to do so after I install the TNT kit. Ill let you know when I go to the track so you can host a vid here. BTW sorry for the late response
Thanks again for the replys guys

 

so will the PCM turn the fans on when the A/C turns on? or do you still need the separate ground off the compressor circuit?

 

If you get the Nelson harness there will be a wire in the harness between the battery junction box and the block that is dark green. This wire will turn them on with the A/C when you splice into it. If you have the Nelson harness there is detailed instructions on how to hook it up.

 

oh ok. i made my own hrness so i guess i'll have to add that wire. thanks!
