High idle mod....How???

[kevinmach1]

Tell me about the high idle mod, and while we are at it, what other mods are popular for the '05 6.0? Thanks...
So far I am stock, with the exception of the triple dog bullydog. No, I don't have guages. I am running under the radar so to speak.
Thanks....Kevin

High idle is a very easy mod where basically you attach a toggle switch between the "hot" wire behind your OBDII port to your PTO power wire behind your fuse panel. All 03 and up SD's are wired from the factory with a PTO bundle. Once you have the jumper in place, step on the emergency brake and flip the switch. Your truck will idle up to about 1200 rpm. This one's a good idea for anybody who idles their truck for long periods of time. I did this to my truck for about $5 for the wire and switch. Another freeby mod is the zoodad, which is where you cut a hole in your fiberglass radiator support behind the front grill and directly in front of the air filter housing. Gives you a fresh source of cool outside air to draw in. Most people put up a screen of some sort over the hole too to keep things out.
