High idle mod question

[colinmitchell111]

I just did the high idle mod. I used this video.

When i first read about this mod I thought it was kind of stupid to have 2 switches, one being the e brake and the other being a toggle. Someone said that you could jump the 2 wires together and the only switch would be the e brake so thats what I did. Well when I did that the high idle was always on regardless if the e brake was on or off. So I ended up hooking them up to a toggle so its just on or off with the toggle. It worked out good because thats the way I wanted it not to have to worry about the e brake. I kind of want to know why its working regardless of the e brake though?

What you read about not having a switch was probably my comment. I have an 06, and from 05-up, the high idle mod is different.

Thanks for posting the video.

We tend to miss that 03-04's are different than 05-07's. (just posting this for future searchers)

Apples and Oranges.

03-04 = Apples

High Idle Mod

05-07 = Oranges

03-04 do not use the E-brake.

Ok thanks guys.

My e brake has a history of quitting it's job, is there a way to bypass the e brake wire and use just a toggle for the 05-07?

Are the 05+ trucks different only because of the upfitter switches? Because mine doesn't have them.

No, they are different because of PCM programming and wiring changes. The mod has absolutely nothing to do with the upfitters, other than you can use one of them to activate the high idle. I have no switch on my truck, and have it straight wired to a key-switched 12 volt source (with inline 5 amp fuse). Once I set my e-brake, the high idle kicks in. One hunk of wire less than a foot long and an inline fuse holder was all that was needed.

Sure, but you would have to live with the "brake" light on the dash being on all the time....
You would have to bypass the switch for the e-brake.

Aha! Thank you sir! That clears it up for me.
