wody Posted October 10, 2006 Report Share Posted October 10, 2006 anyone wired a manual fan switch in their 05 or had two switches for each fan? i was at work the other morning sitting in my truck eating breakfast when i noticed my temps started to jump to about 220 and since i didn't want to be an ass and raise the rpms with my cutouts, i had to turn the a/c on just to build head pressure so the fans would kick on. the ambient was about 55-60 and i really didn't want to run the a/c. living in las vegas this time of year is nice cuz at night you can either run without a/c or have the windows down, but in traffic or parked my temps jump. schematics would help too. thanks Alan Link to comment Share on other sites More sharing options...
04CHASE Posted October 11, 2006 Report Share Posted October 11, 2006 the pcm4less harness for adding 05 e fans has one and thats what i use, i also have e fans on my i/c so i just keep it on when at the track, i think all you would need to do is add a ground switch for the fans to come on. you need to check a wiring schematic Link to comment Share on other sites More sharing options...

Bowtie70SS Posted October 11, 2006 Report Share Posted October 11, 2006 PCM4Less no longer sell fan harnesses...here is the link for a miring diaghram on PT There are several others posted. You should be able to just jun the switch to the wire coming out of pin 33 and to a ground. Turning on the switch would ground the relay and kick the fans on High (I think) but I'm not 100% about the fan speed. Look on Performance trucks, there are pages and pages of info under the engine and performance section. Dave Link to comment Share on other sites More sharing options...
