trying to wire the ground function now, thanks

 

Ive got mine, but wont be able to scan them till around 5:00 PM CST

 

thanks, thats better than nothing, really need one now though

 

Do you just have the single ground wire that goes to the PCM?

 

check your pm

 

thanks, how do I wire the switched ground feature?

 

your talking about adding a toggle switch to control the fans manually?

if so get a 2 prong toggle switch. (mine is 50amp, don't know if it needs that much).

one wire is going to tap into the wire that goes to the pcm and the other is going to go to a ground.

 

hmm, thats not what I mean, there is a way to have the pcm trigger, a/c trigger, and manual trigger

 

the way that blue cajun described will create a manual fan on (both fans on low) using a ground wire.

you tap the wire going between the pcm and the rest of the original fan harness, then run that to a switch, the other wire from the switch goes to ground - simple as that, when you flip the switch you will ground the same wire that the pcm grounds when the truck gets to turn on temp.

 

so as long as it recieves a ground, either manually or pcm the fans will come on?
