Can someone provide the instructions on how to completed the High Idle Mod, using an upfitter switch?

Thanks.

 

I am interested as well

 

That info has been available for a while.

See: https://www.fleet.ford.com/truckbbas...tml/Q180-A.pdf

Looks like a resistor is now required for all modes.

 

yeh.. now you can control the RPM which you could not do before..

Yea, that document is what you need.
If I remember correctly:
I connected the Brown AUX4 wire from the upfitter fuse box to the Yellow/Green PTORS1 input wire of the PCM. Then I put a resistor between PTO_RPM and PTO_REF.

 

Thanks for the replies. The reason I was asking how to do this mod, is since the truck shuts off after it idles for 15 mins. Will this keep the truck from shutting off after 15 mins? Are there any other ideas to keep the truck from shutting off, as I need the truck to continue idleing for extended periods of time. Thoughts?
