Ford F-250 XLT Super Duty 6.7l - SEIC adjustable high idle modification with parking brake bypass

awesome write up. thankss

Thanks for the great write up. Will help many. Plan on Syria soon.

Are you all stock with your exhaust or have you deleted the dpf/urea? you said you don't need a potentiometer, I assume I would just leave it out of the circuit from your diagram if I didn't want it and the truck would idle at whatever resistor I have installed?

how exactly do wire it without using the potentiometer. Do you just not wire anything into the green wire?

Is the Park Brake wire (white/violet) a terminated wire like the PTO wires (and the upfitter wires)? or do you have to tap into it?

Does the parking brake always stay on? I just see your on in the video.

What rpm happens without a resistor?

Will this still work on a 2015?

Hey man! I'm having a hard time trying to find a 50k potentiometer. Do you think that an interior dimmer switch would work? All the way to the bottom clicks off and then as you dial it up it turns on and gives it more power?
Also, i would like to keep the ebrake safety feature in tack, so would I just omit that relay and connection?
Thanks!
Matt

if you switch the outer post on your pot it will change the direction to increase decrease rpm IE clockwise to increase you show counter clockwise ti increase in your diagram the outer posts are reversible

It works in drime mode

Drive mode

What’s the part number for the potentiometer?

Just a heads up, my 05 has an aftermarket remote start and if I leave an upfitter on and remote it the upfitters do work, I can't say for factory starters, but my aftermarket one works.

With the park brake bypass does the dash light stay on at all times?

Whats the point of not setting the parking brake?

I have the 2011 Which I cant find the body builder Layout... Please help?

Just used this video to install high idle on my 2016, very informative, made it very simple and only took me a couple of hours all said and done. I really appreciate you making this video and want anyone who reads this to know you can do it exactly the same way on the 2015s and 2016s just don’t get tricked by the white brown wire under thee dash, it looks like white black so I skipped past it for awhile looking for white brown

WOW This is great !! Thanks a million because I am putting a BD high idle kit in today and I am so po'd at this piece of JUNK just like every darn thing I have ever seen from BD I am gonna trash it. The thing would be okay if they could actually build something that fit and worked! I hate it ! I am going this way bigger job but way better! Thanks again it is great video and you did a great job!

I think this was asked but for clarification If I was driving down the highway and my friend flipped that switch. Would it cause a problem with anything or would it just not work.

I have tried this with my 2012 6.2L gasser. I cannot find the correct combination of wires. In fact there is no white with brown stripe wire. Which may mean that my truck didn't come with the SIEC. IDK. But also bc its a gas engine there might be a wire that can be used in place of the white/brn PTO REF wire. I bought everything i needed and I'd really hate to have wasted that money. Can anybody point me in the right direction on this?

Where in South Texas? I'm getting ready to do this... lol

Where did you get the adjustable switches at

some trucks like mine u can switch your #4 outfitter to be hot all the time so it will work with auto start. there are vids that show u how to slide the fuse link over for hot all the time

your diagram is correct dots indicate connections if wire is crossing another wire without a dot its not wired together at that point

Can you just put in a resistor and not the potentiometer? I don't need adjustable RPM.

Very detailed!! Love your diagram!! What gauge wire do you recommend I get to wire this up!!

So you have to install an upfitter kit to have this happen?

Thank you for the info, links will not open for the ford bulletins however I’ve got some good intel on the video to make a search. Semperfi 2011 Texas powerstroke! 💯❤️🇺🇸

Hi there, with this installed after you start it up in the morning will the truck automatically rev itself up in the winter with the upfitter switch off?

I saw someone do this without a potentiometer? Are you able to do it with just a resistor to have a set idle? If you can what is the size resistor you need? I heard 22k but that seemed pretty wild to me.

You probably won’t answer seeing how you posted this 7 years ago, but I just tried it on aux3 cause my aux4 is already being used. And my parking brake light is on all the time(with ground connected or not) and it only idles up if the ground isn’t connected. Is this happening because aux3 is a 10amp and aux4 is a 15amp?
