Thank you. That did help, though not in the way I was expecting.

It ended up being the parking lamp 20a fuse............ I'm still a little confused on how the instrument cluster/stereo/parking lights/etc were able to light up with the switch in the right position, but whatever. Also, I swear I swapped every fuse out. Again, whatever.

I'm a little concerned that I have a short in my trailer wiring as I was towing when I originally lost lights. If it happens again I'll start diagnosing from the trailer connector back

 

Hey, at least it was a relatively easy fix.

 

You just had to say that didn't you..... Haha, blew another fuse this morning while towing the boat. Probably means a short in the trailer wires somewhere. Also might only be when I have pulled the headlight switch out one click for the driving lights and tail lights. Hasn't done that before with the headlights fully on.

So either I trace the short or only drive with my lights off or fully on.

 

I would expect it would blow the fuse anyway..... as the running lights are on with the headlights as well, and it's the same circuit in use......
