taillights and brake lights stopped working?

This sounds like the ground at the rear of the truck is bad/off, but we should check the fuses as well. Here is a guide to help you test the fuses and I would check the ground at the left frame rail near the bumper. Here is a guide to help test for power and the tail light and brake light wiring diagrams so you can see how the system works.

I’ll clean up the mating surfaces good and see if that helps. To me it looks like it’s underpowered or something since my test light lit up on both bulb sockets, one was dim, and the other was bright. I checked all the fuses, and they were all good, for whatever reason the fr park fuse stops them from working.

That ground looks like it needs to be redone, clean the metal and replace the crimp on connector, also to see if this is the problem use your test light connected to ground on this wire when the brake are depressed, if the test light illuminates the ground is bad.

anything?

Yeah, my bad, figured it out a couple of days ago, I must have had a faulty LED bulb In The front, thanks for the help. Learned a lot about this darn truck trying to figure that out, lol.
