He's got step two taken care of. I may make the harness, we'll see though.you would need the wiring harness and would also need your PCM tuned in order to turn the fans on/off via PCM
yeah get a junkyard fan or two and get a thermo switch for $25
yup,it has all wires you'll need. the fans you buy have a female end for a plug to plug into them. the harness that you buy has the male ends to plug in to the fans. PM DLH2006 over on Performancetrucks.net He makes the same harness much cheaper than Nelson Performance.[/QUOTE]cool man!
[quote="GMforLife, post: 1231705"]ratt ron i believe makes harnesses too PM him. The harness plugs into the fan and also has the wire to tap into the pcm. You need your fans activated by a tuner, or someone that has HPTuners or EFI live or something that can help you out.[/QUOTE]thanks Andrew! I even include an overdrive pulley for the alty to help them little whippy 105 amp units out.:evil:
