DIY High Idle

I saw a few threads about this so I figured I'd pull my thread from DB and post it. Keep in mind this is on a 2007 (same wires for '05-7), but it's about a 10 minute job (including going back to the toolbox a couple times. Also, I took the pics after it was done.

What you will need:
1/4" or 3/8" DR ratchet
10mm socket
Wire stripper/crimper (actual stripper will extend job time to 30-45min)
Butt connector (without upfitters you will need about a 3' length of wire and a switch with a second butt connector and appropriate connectors for the switch)
1-2 beers (optional)

First you will need to locate the PTO wire bundle under the dash behind the e-brake release handle and find the Purple w/ Green stripe


If you have upfitter switches skip to next step

Find the lonely White w/ Blue stripe wire under the opposite side of dash above gas pedal (this is a +12V wire when ignition is on that goes to absolutely nothing) and connect these 2 wires to the switch which is mounted wherever you feel like at the moment (inside the cab is recommended but to each their own)


Back to the upfitters. Pull off your dash access panel and remove the 4 bolts that hold in the fuse box (as you can see I'm not cheap on tools)


Carefully pull the box out and locate the harness for the switches (4 orange bundled together)(notice that there are 2 18ga wires, these are AUX #3 and #4, and 2 ~12ga, these are AUX #1 and #2)


Pick either AUX #3 or #4 because of the lowered amperage, I went with #4 just because of it being closest to the shifter it's easy to flip it and do a neutral check, strip the wires and apply butt connector (or solder/tape if that tickles your pickle better)


Do a test run





Button her back up and enjoy

Another VERY important note, while you're under the dash stripping and mating wires PUT THE TRUCK IN GEAR!!! When I stripped the Purple wire my wrist hit the brake release and next I knew I was rolling down the driveway (only a couple feet before I slammed the pedal back to the floor with my hand, but enough to chirp the tires when I locked it up)

so i take it the job took about 45 to 50 mins? jk like the shifter knob

[PowerSmoke07]

Lol. I'm not sure where my badass one went, looks like a .50 cal muzzle

Got any better pics of your shifter knob? I need more ideas.

[PowerSmoke07]

Sure, paint is a little beat up where I have a habit of tapping my ring on it

[Lilpooh]

Paint? Is it an aftermarket that you adapted to the splined shifter rod?

[PowerSmoke07]

Yea, it's aftermarket from I think it was Kragen, came with the different little plastic inserts and has the 3 allen head set screws (if you get one of them, LOC-TITE the piss out of it, those babies will vibrate loose SO quick)

I'll keep you in mind the next time I make weighted knobs. If you want one, I'll put you on top of the list.
