Cruise control stoped working after engine harness changed. - Finland25 - 01-19-2020
Hello guys. I have a cm570 ISX and I changed engine harness recently. After that my cruise stopped working. My jakes is ok. Everything worked well before so that's not a pedals issue. Need some advice where to look at? Maybe shop forgot to hook up something? Thanks.

First, check the fuse and any relays if there is one or more, I do not know. What truck is this? That will help too.
Also, this may sound silly, but is the harness wired for cruise control? My buddy just replaced the harness on his Freightliner with a Detroit, same issue, no cruise control. He ran the wires and discovered they were not there to operate the cruise in the new harness.
Do you still have the old harness to compare with the new one? That is how he discovered the issue, along with having a copy of the wiring schematics.
