‘21 Pete 389 no cruise or engine brake

Both worked until Sunday. Sunday I took the factory installed CB out and installed mine. The plug that is hard wired in would not fit on my CB so I put a plug that would. In the process two wires touched and arched briefly. The cruise shut off, the info center with GPS & radio reset, and I lost power to the CB.
The cruise indicator comes on when I turn the switch on, but the cruise does not set. The engine brake indicator light comes on and the lines that indicate what stage it’s set in comes on and changes as I move the selector arm, but the jakes don’t engage. I also don’t have power to the CB through the factory wiring.
I checked the fuse panel behind the clutch and the fuse for the CB is not blown. On the diagram there is not a fuse marked for the cruise or jakes. Is there another fuse panel somewhere else? I didn’t see one under the hood, on the firewall or under the bunk.

 

How do you know the fuse isn't blown? I've learned to not trust ANYHTHING except a continuity test on a good multimeter or simply replace said fuse (cheaper).

 

I watched that video. It’s 10 years old and two of the fuse blocks he mentions are not in my truckI

I pulled it out and looked at it. I would check or simply replace the jake and cruise fuse if I could find it.

 

Wow. Sorry for the irrelevant info then. Sorry i couldn't be more help.

What was the outcome from this? I’m having the exact same issue and need help.
