99 F350 Running lights/wiring

1999 F350 CC 4X4 SRW LB

My rear running lights and license plate frame lights are out. All my blinkers/flashers/brake/backup lights work just fine. I haven't been able to find any bad fuses in the process and I can see that there isn't any 12V going to the running light filament. I suspect there is a bad connection somewhere. Where can I find a wiring diagram to track this down? Any help would be appreciated. Thanks.

You're going to have to trace the brown wire coming out of the headlight switch. That circuit powers all the running lights. You can try piercing the insulation with a pin to check for voltage at various points in the harness. There are connectors down below the master cylinder on the fender liner. One of them carries this circuit between the body harness and the chassis harness. Start there AFTER you confirm that the fuses are good using a test light or multimeter.

Could be that your headlight switch is bad.
