Ideas on how to hook it up to the computer?
I asked the company i am having do my custom tune to turn the fan on in the pcm but i dont know where on the pcm to hook the leads up to.
And am not sure how to do it
Thanks!!!!!!!!!!

You would actually connect the leads to a relay(s). The pcm won't supply nearly enough current to power one fan, let alone two. :D I don't know which pin is the key.

The PCM isnt setup for fan output on the S-series.
Just need a adjustable (recomended) fan thermostat a relay, wiring and some instructions.
I can assist there.

Firefighter had told me i could run the fans from the pcm since they are the same that run the ls1 anyway it just needs to be turned on!
But thanks! I will def need some help with that!

You got a good deal man!!

Thing is, the PCM is the same but the programming is different. Im sure the PCM has 2 more injector pulse outputs, but that doesnt mean the 4.3 flashed program supports it. I was assuming that since the S-series doesnt have any e-fans in the model line, that they didnt program the fan switch output. IDK, I could be wrong. But there is a coolant temp input sensor. But they also have a AC Compressor signal input. I believe DkGreen-White at the compressor plug or the C2 harness at the PCM could be used to trigger the 2nd an during AC useage or diose isolated and parallel with the thermostatically controlled trigger.

Does the fan need to be modified to fit in my truck?
