Brake light problem FIXED

This is a 2000 2wd ac, new frame. I have a problem with brake light on the rt side. (and reverse light). I looked for pinched or chafed wires. I changed bulbs. I don't see a problem.
There is some kind of module behind the rt. taillight ass'y could that be it?
I'm still looking for ground wires but I don't find any at the rear.
Sure would like to find the problem myself (Chiltons manual is crap for this)
Thanks for any help!

Found out that switching bulbs side to side worked. Switch them back and same problem. I'll go buy some bulbs but I think its odd! The reverse light problem was just a bulb.
Still don't know why there is a black box behind the left taillight ass'y.

GPS tracking device. Rip it out!

Seriously, any time I've ever had any kind of trouble with tail lights on a truck, it was due to a missing ground. The +12V of the circuit needs to find a ground for completion, through whatever means it can, and will cause crazy shit to happen back there with the lights.

Thats what I went for, but there isn't any that I found. I think the grounds are all in the front, maybe at the fuse box. Oh well its working now...
