    Default How to get high idle to work on a manual truck with cruise control buttons?

    I read in an old post that Les was saying a certain pin had to be grounded on the ecm to enable high idle on the manual trucks. Does anyone out there know about this?

    I believe it's the same for the autos... I don't recall the pin, but I know I have a switch wired up to my ECM that enables the PTO high idle that uses the cruise buttons.

    For all the autos I do I just use a base file that has high idle enabled. Never had to ground any pins on the ECM.

    Correct, on an auto, no pin grounding, just need a base file with the feature enabled.

    On a G56 truck, pin 26 (I think) needs grounded. Then a base file with the feature enabled needs flashed in.
