I just installed setup yesterday and idles up to 800 perfect but won't move past that with cruise buttons ?? I just took truck for a drive to check cruise control operations and works perfectly , looking for any help or ideas ......:help

You push the set button for 800, and the resume for the 1800 RPM. Is that what you did-?

If i flip toggle on goes to 800 and then if i try set cruise button does nothing but stay at 800 same with accel button ??

OK, I posted incorrect info-- on my 04.5, I turn on the PTO switch, [no foot on brake and in neutral]

I press the set button 2 times to activate it
-- and then it goes to 1200-- if I slide the resume, it goes to 1600. Sorry

Hope this helps.

I just went out and tried as you described and still won't go above 800, thanks for your input I do appreciate it !!

accelerate slider has to be in the on position.

I do have accel slid to on also , I even tried slid off LOL... Just odd I haven't heard of this not working unless cruise doesn't work because a blown fuse or something else ...

Well since the cruise still works and its not bumping up maybe one one of the pins is not contacting all the way? Mine runs at about 800/1200/2200

Press toggle... Goes to factory 800
Press set button.. jumps to 1200ish
Slide accel... Jumps to 2200ish.

I also have the ignition override so that I can just push one button and pull the keys and she stays on. Its only like 7 hours of wiring.

First test-- make sure you have 12 volts to the switch you installed, and 12 volts out of the switch and to the ECM.

Yep those are the instructions i followed ..... I can see from the front side of plug that pins are both seated ?? does anyone know if one pin or the other has to do with cruise control part ....... Or would it not work at all without both pins making contact ???
