Hi my name is Robert...

As a general rule they like to stick that connector in front of the steering column on the fire wall, some might have a carpeted panel and it is behind that panel, it also might be bundled up with other wires in that area, that is normally where it is located on the Workhorse chassis.... Robert

Tanks, I'm having brake light issues and cruise control issues. The engine corrected when I restarted after 20 mins. Fuses and bulbs are good

I do not have much info on that circuit, I do know on some set ups if you have a brake light out then it could possibly cause the cruise to shut off, to me this sounds like you could have a loose connection at some point if the problem is intermittent. I am not so sure you are going to see a code unless the engine light is coming on. I would also inspect all your battery cables and make sure they are clean and tight. Always want to rule out a the battery or low voltage condition. I might have a shop take a look at this one... IF you would like to try another expert please let me know... Robert
