High Idle Mod Help

[Reezy71x]

Wanting to do the high idle mod, but I do not have uplifter switches. Can anybody direct me to a how-to thread or do a write up for me? Thanks

Here ya go bud. I got mine hooked up to a switch that was installed by the previous owner on my truck, put it right next to my in cab winch switch so that way when I run my winch I know I'm making more that enough power to run it. The high idle was more for emergency vehicles that need to run alot of things at once, this wasnt designed to be for warming the truck up, although it does do that too...

What years can thus be done on??

[USAFBowman]

I believe '03 plus, and in like '05 (ish) the wire color got changed

i think it can even be done in the 99 and up 7.3, since they also came as ambulance and tow chassis.

if you want to use it for warming the truck, start it. let it kick itself into the factory high idle,which it will do about a minute after starting, and then flip high idle on. this gives it time to circulate oil and lube everything fully first.

I did the high idle mod after watching this video. It only took about 15 minutes to do. It's the nicest free mod I have.

the factory idle is high enough for startup, and sitting at a traffic light. on the other hand if it needs to idle for any length of time a higher idle will raise cylinder temps which reduces fuel wash on the cylinder wall, reduces wet stacking(which leads to another whole bunch of problems). long idles at low rpm just cause all sorts of problem, personally many of the issues that gave the6.0 a bad name have at least some if not all of their root cause in extended ;ow idle time.

as far as with the manual tranny I never found a way. for some reason ford saw fit to install the pto programming on the auto's but not the manuals. I think you would have to request it being loaded by ford or an aftermarket tuner, then it could be enabled.
