I did the search ddnt find what i wanted.. I was wondering if there is a way to turn on the e-fans in my stock pcm with out using a a tuner. i dont have a tuning program and plan on making my own harness for a set of ls1 fans. I would think a chevy dealer could do sence I can do it at my dealer..(chrysler) anyone have any idea's?

 

I've never heard of the dealer being able to enable the port for the fan control?

 

you could run a manual switch of coarse:-P

 

well with my "DRB" i can turn off and on almost anything in the pcm and body computer. ie: Day Time Running lights, egr, door locks and so on, i would think a GM scan tool would have the same technology i could be wrong. well anyone know how much a nelson harness is i look on there site and they dont have it posted.

 

the nelson harness is around $85-$90 I think

 

Im not sure, but you might be able to do it with a Tech 2, you can also run it to a temp switch.

BTW got your PM about the harness.

 

you can do like white one said and run it to a temp switch. they run 15-20 bucks for a switch....
