    I have a 579 and a Minimizer seat that needs power
    In my last truck I just added a new fuse and ran a wire back to the seat

    I have this connection that’s already behind the seat and assume it should be hot or able to be but either I am not getting a good ground with my test light or there’s a fuse for it that needs to be installed
    Any ideas?

    With all the computers in there now it may have to be turned on with a laptop.

    not to highjack the thread but @Long FLD any chance you could PM me a picture of your fuse cover if its a 17 579? More then 3/4th of the diagram in mine is missing....someone aprayed something all over it before i bought it and having an intact one would be useful.

    Yeah
    Not seeing it there or on the firewall one
    I do have a 2021 so maybe it’s changed

    I do have one under the bunk I will also check
    Maybe there?

    If there’s no fuse then it might be something controlled by the cab control module like @062 said. I’m out of guesses if you can’t find a fuse for it.
