I've read posts on how to hook up the high idle. Last night I went to complete the task, but had no luck. I easily found the wires and ran a jumper between the upfitter #4 switch and the solid orange in the pto bundle. Had power but no luck with the high idle. Any ideas?

Thanks in advance for ideas.

 

No expert here, but I just hooked mine up a few days ago and it worked fine for me. I also have an '06. But I used the BCP wire. Maybe try again using that wire??? Also, check your brake light bulbs.

Did you set the parking brake?

 

Thanks for the replys. I did set the parking brake and have doubled checked that all break lights work properly and tried the purple/light green stripe and also the orange wires to switch #4. I tried again tonight, still no luck. I'm fairly good at following directions--especially these ones so I think there must be a different problem. I'll dig deeper this weekend.

Again, thanks.

 

Do you have instructions for attaching to the auxiliary switches?

 

If you need to install the switches, see:

If you already have the switches, but need to know how to connect to them for use, see:

Hey everyone!

Been lurking around here for awhile now. I just bought a 2005 F-250 SD V-10.

I hooked up my upfitter #4 to the solid orange wire. Idle goes up to about 900 rpms. I want to hook up a variable resistor to adjust the idle speed.

Does anyone know the correct potmeter to put in? By that I mean the correct ohm range.

Thanks!

 

There is a resistor/rpm chart in this document:

Thanks! Thats exactly what I was looking for!

 

Probably should use this one for your 2005. It's probably essentially the same, but you never know.

does anyone know if there is any way to go above the factory idle but lower than the 1200. I would like to set mine at about 900-1000. The mod works fine in mine but sometimes I need to take a nap in the truck and the 1200 is kinda high for that.

 

It's been a while since I did the mod so that penguin may have fallen off the iceberg, but IIRC, the PTO setup with either resistors or a potentiometer works backwards. I would think that more resistance equals lower idle but, as usual, I'd be wrong. No resistance equals 1,200 rpm and more resistance equals higher rpm up to 2,400.

I can think of two ways to do this. The first and most effective is to figure out how to fool the truck into thinking it's cold. The elevated idle that it automatically goes into when it's cold is about 900 rpm or so. If you could tap into that system with an upfitter switch, you'd be catchin' z's before Snoopy was done barnstormin'. You'd probably be a hero if you could figure out how to do this.

The redneck, and therefore foolproof method, is to remove your boots. After all, you're about to nap, you won't need them. Then wedge one under, around, or over the accelerator until you achieve desired results. If you don't wear boots, go buy some. You can't be a redneck if you wear loafers.

 

Yeah, I gotcha on the redneck boots. One way I have tried is my wife sewed a key ring onto the seat cover and I had a sliding adjustable broomstick and put one end into the keyring and the other into my shoe that was on the pedal. Ok all kiddin aside, I understand your idea and I really think you are onto something. Does anyone know what voltage range the coolant temp sensor and the oil temp sensor runs in. Also does anyone know what other sensors measure temp in the truck. I think I can get intake air temp on the edge. That's gotta come from somewhere.
I also have another idea. What do you think about using the feed from the drive by wire? Since that already controls the rpm's using an electrical signal, I wonder what the odds are of acheiving the low-high idle that route?

 

I have a 06 550 and tried the upfitter high idle and all it does is choke the engine down and turn on the electronic throttle control light

 

Mine didn't work either I have a service body on mine not the stock brake lights don't know if that matters but any way that was with the Orange wire so I used the bcp wire its purple with a green trace and it works great
