74 step tail lights stopped working

[69Tom]

I've been doing a bunch of reading through threads on here, but wanted to make sure best way to do this.

Basically, last night my running tail lights stopped working. I had an issue with the truck where the truck wouldn't shut off. After much troubleshooting, I determined the moron working on my exhaust pushed the positive battery cable at the starter into the terminal with the ignition wire, so I was getting constant voltage to the coil and it fried the coil. I adjusted the cable, replaced the coil, and issue solved. Except now my tail lights don't come on.

Brake lights, dash lights, side marker lights and directionals all work.

I partially dropped my tilt column to check my ignition switch when I was dealing with the coil issue (thinking the ignition switch was the problem), but really didn't move much of anything around other than the switch. Not sure if I somehow pinched a wire.

As such, and from my reading, this is not a fuse issue, and most likely a ground issue, correct?

Also, I'm guessing it's not a bulb as both sides are out?

I'm in AZ, so not much rust here, but stuff still does get rust, so not sure if the mount to body ground on the tail light housing is the issue.

Just weird it happened all of a sudden while I had this coil issue.
