High Idle Switch

[twinturbos]

Not exactly sure how many people have posted on here about this, but I saw a guy on a youtube who flipped a switch to enable the high idle. Seems like this would definitely be handy to have (even though my truck automatically does it, usually when its cold out here in Iowa winters.) I currently have a 2008 6.4

Does anyone know where you can get a kit, or if it's simple enough to actually install a DIY type switch? Not sure exactly how much work this would be, but thought I'd see if anyone out there knew much about it. Any help or websites for consideration would be greatly appreciated. Thanks!

This applies to 6.0s but i am sure the 6.4 is similar. The computer has a high idle PTO wire typically used on service trucks to speed up motor for alternator or hydraulic pump. It works by that ECM PTO wire being grounded, and the parking brake being set. You could also have that PTO wire ground through the parking brake, so when you set the brake it will go to high idle.

I have it on my 6.4. Works awesome on cold mornings. Just hook a powered switch to the wire labeled PTO under your dash. If you google it you should be able to find a lot of info. I just used a butt connector and hooked my Upfitter AUX4 to the PTO. In order to activate high idle you have to be in park, parking brake on and flip the switch. It can be turned off by flipping the switch, releasing the parking brake, or hitting your brake pedal.

I looked up some of the info on it. Doesn't sound like it'd be too hard of a job, however my 08 didn't come with the set of up fitters. I saw a set on ebay for about 160 dollars. Probably need to get that in first!

With the upfitter switches this mod takes 3 min to do. You can easily hook a switch too it or just order upfitter switches.

AGREE!!!!

You dont have to use a switch.

Hook up the pto to a power wire, then just push the e-brake when you want high-idle.

I even have mine setup for remote high idle. My remote-start system has "aux" functions, so I have a relay that "turns on" the parking brake when I hit the button, then the truck high idles. I havent used it much as mine high-idles really well on cold mornings by itself.
