High idle mod for a 2006?

[0660BigHoss]

I see this posted all over the place for 03-04, but does it work for the '06? I would assume so. I'm sure there is a link with the details around here somewhere. If someone could point me to it, I would definitely appreciate it. I have heard that the wires may be different colors than the 03-04 and I definitely don't want to wire up the wrong thing.

Thanks in advance!

The mod is even easier for an 06.
Right above your E-brake pedal there is a little bundle of wires.
Go through them and find the purple with a green stripe wire.
Apply a switched/fused (or just fused power that is live at key-on) power source to that wire.
Congratulations on performing the high idle mod on your 06!

To engage high idle:
Set your e-brake, have the truck in park and do not touch the regular brake. Turn the power on (or just wait if it is a key-on source) and wait a few seconds. The high idle will kick on.
To disengage:
Release the e-brake, touch the regular brake pedal and the truck drops the idle back to normal. (or flip the switch off, if installed)

Wow. I spent about 1 hour with no luck. Dang. Here's what I was doing. I want to tie it into upfitter switch #1. Book says it's Orange and Light green. I don't have a orange and light green. So tried a different orange wire. Found purple with light green stripe. DID NOT WORK.

Also found 2 light greens with a purple stripe. Neither of those worked.

Tried every possible combo of orange wire with the purple with green stripe and it still did not work.

Totally lost at this point.

The book you are referring to is likely discussing the mod for a previous year.
You have an 06. The wire is purple with a green stripe.
The high idle does NOT engage immediately. It takes a good 5 to 10 seconds before it engages and you must meet all the criteria above.

12 volt power to the wire, E-brake must be set, truck in park, do not touch the regular brake pedal. Wait 5 - 10 seconds. High idle engages.

Here is a direct quote about this from FORD:

PCM Pin C1-09
Circuit No. 2248
Wire Color: Purple / Lt. Green

• Applying vehicle battery voltage to this wire begins BCP. (battery charge protection)
• Engine speed is sent to 1200 rpm when all safety enablers are met, regardless of
the degree of battery charge.
• After 1200 rpm, BCP regulates engine speed based upon the degree of battery
charge, up to 2400 rpm maximum.

By the way, upfitter switch numbers 1 and 2 are 30 amp, which is WAY too high for this, IMHO.

Wow. Mine goes up almost immediately. And it makes the whole truck move. Almost like if the ebrake were not set, it would lunge forward. Is that normal? It does not seem so from the youtube videos I have seen of this. Seems like it's effecting the torque converter.
