I am looking at doing this upgrade with the Nelson wiring harness. I was just wondering what controls the fan turn on points? I know with a stock e-fan setup the fan settings would be in the PCM.

ok heres what i got. LS1 fans from a 2001 camaro SS. I used 3 1" by 1/4" stainless bolts, washers, and nylock nuts. And for the mounting brackets i used 12 gauge stainless steel and i believe they are 3/4" wide by 3.5" long. turned out pretty good, took me about 2 hours to get everything off cleaned up and then back on. i have more pics if anyone wants em i can send em to your email.

ya the pcm controls the fan speed and when they come on and for how long based on the coolant temps it sees i believe. the nelson harness was super easy to install as well. just that dam green wire for the A/C that took me two tries to find, but oh well.
Nicely done, thanks for the pics!
I will have to look at the PCM fan settings after I get my HP Tuner.
Will the the fans from a camaro fit in a 28 inch rad?
ya thats what i have is the 28" radiator.
How much was it all together?
anyone know the CFM the stock ls1 fans put out?
it was 100 for fans, with shipping, 100 for the nelson harness, and i had my pcm tuned at the same time which was 375. is not bad. i can garuntee that the electric fans put out wayyyyy more air flow than the stocker. in the summer if i am idling and walking near the truck and the fans come on, i can feel the heat they are pushing out of the engine bay
just pick up some 14 inch fans for my truck from one of my friends that work for performance auto fan manufacturing company ,if anyone needs some fans let me know, i can get them for a cheap price,i will post pictures of fans being installed and the fan housing i am going to make also for the radiator,pics comming soon .:cowl:
