Fast Idle Switch

[haulin8or]

What you want to do is hook the Blue/white wire to a switch and the other side of the switch to +12 volts. When the +12 volts is hooked to the blue/white wire the truck goes to high idle.

Thanks Dave! I will be doing that next weekend for sure! Is it easy to find the blue/white wire under the dash? What area should I look?

I'll save you two hours of looking and tell you that the blue/white wire doesn't exist on Excursions. F250's and 350's yes, X's no.

Bottom line, you've got to run the blue/white wire yourself from the PCM to under the dash. Everything is explained in this thread, just read through the comments and it'll make sense. About 5 or 6 of us struggled through this last year and finally figured it out! It's not too bad once you're armed with the knowledge on how to make it work on the X. The hookup is the same on all X's with the 6.0, regardless of model year.

PM me if you have any questions--glad to help.

That's the least I can do! When it comes to the advice department from SDD.com, I've taken a helluva lot more than I've given!!

I just wish I'd grabbed more connectors from the dealership so I could send Haulin8or one, but I could only salvage a couple and both got used on X's at the time.

Yes, thanks for chiming in on this thread Bruce! After reading the post on that mod, I wish you had a couple more too Thanks for that info, I still want to do this. Who did you speak with or ask at the dealer? The parts dept? a service writer? I used to know someone at the parts dept. at my local dealer but he is gone now I don't have any contacts at the dealers around here as I usually do everything myself, and knock on wood, have not had to take it in for any warranty issues in a long, long time.

The high idle switch is great. I idle mine on fast idle about 14 hours straight during the winter - yes, I can afford the fuel.

I agree with what was said above, about starting the truck and kicking it to high idle to warm it up/cool it off inside, but you might want to start it up, and let it idle for a few seconds before you kick the motor up to 1200rpm... especially if it's REALLY cold outside. something about the cold makes the oil nice and thick, and oil don't flow that well when it's thick.

read me
its the ford site info on wire colors and resistors for the batter charge protect or the pto high idle

i have since a few weeks ago removed my pto high idle function and rely soley on the battery charge protec circuit for high idle

oh and FWIW batt charge protect will ramp up to 1200 rpm, and will vary engine speed anywhere between 1200 rpm up to around 2400 rpm MAX based on electrical load demand
i have yet had it run any faster than 1200, even when the batteries where pretty low on charge.
