The wiring harness for the visor is attached directly to the lamps and then goes into the cab. There is an overhead harness which is part number 20913351 which the overhead console will need dropped down to access that plug and to replace the harness if needed.

we have a visor with the wiring harness for the lights. the wire from the inside the cab was damaged and there isn't enough wire left just inside of the roof to repair the damage to it. We need to run a new wire or locate that wire someplace lower so that we can circumvent the damaged portion and re-attach the required connector. where is the best place to reach the wire the fuse box or someplace else?
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 4 months ago
The best spot if you wish to run a wire lower would be to connect it inline with pin 87 of the marker lamp relay R38. The wire goes out of this relay thru the overhead harness to the sun visor harness. The wire number is *****

No running lights on 2017 4300 box car. There are lots of
there are lots of stories, and i just became involved. What I know is first i found the rr marker light wire had parted and shorted to the frame. I repaired that and check the fuse box(s), all seemed fine and although there are complete descriptions for cigar lighter and CB wiring, there is no fuse for marker/clearance lights. Took switch apart and all 4 LEDs and buttons seem to work properly. Then went to junction box in back on frame; 5 wires on brown pin. Powered each of these and all clearance lights worked fine. But there is no 6th wire to bring power to the box, so somehow the cab marker circuit must also power this box. I can find no information online indicating how power gets to the circuit other than reference to 'system controller' box on wiring diagrams. … read more
