Electric Fan Help!

Wow Thanks RED you don't even know i really appreciate you taking this project on for us, I only have 3 relays though? and allen's instructions only have a wire for pin 42?

I am going to try to get a hold of Allen and see if he will do the adjustments? :thumb: I haven't drove my truck in 3-4weeks i want to have it done right?

Thanks REDHEARTBEAT
you were a great help

Hey guys just talked to Allen, REDHeartbeat has a great idea but, allen said it will only work on 04' and up model trucks,. He says we have them hooked up right? I asked for some other solutions. Right now we have one fan on 12V High, I mentioned maybe 2 fans 6V low speed, he said he would send me a diagram on how to wire it and should lower the drag on the alternator. When i get it from allen i will post 1st thing.

Thanks Guys,
BTW if you have a 04 and up go with the whole pin 33 like RED said :thumb:
Allen said he tried it on earlier models and would not work.

You can always go and buy an old idiot light type water temperature switch to trigger the high temp fans. Just have to find a place to put it in the water stream somewhere. Go to Orielly's and look in their sensor book to find one with the correct metric threads. Cross reference your stock temp unit to see what size thread is there. The book will tell you what temp they switch on. You might get lucky and find one designed to turn on electric fans at a lower temp. You can screw it in on the passenger side head closest to the firewall if you don't have something there already.

Anyone have a spanish to english dictionary. HAHA :laugh: You can tell who know's heir shit and who don't?
Thanks, Even though i have no clue what your talking about :thumb:

:lol: :wave: :point: :rofl: :point: :rofl:

I think having 2 fans run at low speed will be better that one working heavily?
What do you guys think, I figure it will take the big draw away

cool thanks guys, he hasn't emailed me his diagram, he said it just the moving of a couple of wires? hopefully this will work :whack:

Think we have narrowed it down to Allen's harness the harness is not designed for the larger 2005 fans but for the LS1 fans , so we need to figure out how to make it work with the 2005 fans.
What I found out is you need to use the pin 42 (low )and pin 33 (high) from the PCM and not run the fans on high speed unless 210 or more temp is reached .
Need to find someone that could help with the designing of the relay layout and I think we could solve this problem .

Here is a pic of how I wired mine. I have an a/c presure wired in as well.http://i10.photobucket.com/albums/a1...e/P1010017.jpg

Am I missing something or does Relay 3 dead short to ground when activated?

Are the little arrows a diode?
