High Idle Modification By LDH Ford Powerstroke Diesel Forum
Slide your driver's seat all the way back. Pull the plastic panel off that covers your fuse box. It's right there in front of your knees. Now take a 10mm socket and remove the 4 bolts that hold up your black fuse box. Just let the fuse box hang there. Now look for a batch of wires near your emergency brake pedal that are all blunt cut with white labels on them. One of them will be labeled "PTO". Strip 1/4 or 1/2 inch off of the end of this wire. Now look for a batch of wires behind the area where your black fuse box was mounted before you removed the 4 bolts and let it hang. There will be 4 wires labeled "AUX 1, 2, 3, 4". Strip 1/4 or 1/2 inch off of AUX 3 or 4, whichever one you want. Now take a piece of wire that's about 6 inches long, strip both ends of it and twist one end around the PTO wire and the other end around the AUX wire. Put some black tape around both ends and that's it. Bolt your black fuse box back up in it's place and put your plastic cover back on.
To use the high idle mod, put your truck in park, push your emergency brake pedal down, and flip the auxilary switch that you used. Give it a second, and it'll slowly idle up to 1100 RPM.
If your truck isn't equipped with with the Auxilary switches built into the dash, buy a toggle switch, tie into a red 12V wire somewhere and use it. Remember, 12V at 10 amps. This is why you use AUX 3 or 4 instead of 1 or 2. AUX 1 and 2 are 30 amp switches.

To the OP. Since your truck is a 2006 you can use wither the BCP wire which is a purple wire with light green stripe, or the SEIC wire which is solid orange. Then you are going to want to use either upfiter #3 or 4 since they are only 10 amps. Number 3 is a orange with yellow stripe wire and #4 is orange with a light blue stripe.
Also please use proper crimp connectors when connecting the wire. Dont just twist them together and electrical tape them like the write up says. I am a heavy duty mechanic and I always get complaints from truck drivers about lights on their rigs not working sometimes or flickering. First thing I do is look for wires wrapped it electrical tape and 90% of the time I find green corroded wires. Crimp them together properlly and the lights work great. Not saying the wires under your dash will corrod and turn green but I like to do things the right way and only once.

Thats a good write up but I might add that in my 2005 none of the wires were labeled with white labels like that writeup says they are.

I am not sure why mine wasnt labled but I wasnt worried the write up in the tech folder was fine. My truck is an 06 but it was built in 05. Its been good except for a few little things so I am thinking mine wasnt built on a Friday or a Monday...well atleast not before or after a holiday weekend anyway.
