R brake and R turn signal dont work.

I have a 03 3500 diesel. Just bought it for a work truck. Very clean, has a new aluminum bed on it with 5th wheel. It had standard lights in the bed. The right turn was blinking very fast. The left didn't work at all. I put all new led utility body lights in it. Everything seemed good, they all blinked fast but I was waiting on resistors to show up so didn't check break lights or look at r turn signal until today. I was going to put a new 7 pin socket in it. The old 1 had a broken cover. When I put a pipe on the brake to check them, no right side. Even the upper front box light doesn't work. Everything else works. BU, L- side Everything, all front, 3rd brake, cab lights, and all markers. I have all the wires loose and hanging in the rear. I don't get the colors going into the trailer socket. There is no green. I cant get a R blinker to light up in the trailer plug either. I traced mid cab under truck and test lighted the green with brake on and it lights up. I tried the turn signal and nothing. But when I tested mud cab for left turn, when I touch r turn with test light the left turn slowed down to normal. I am at wits end. I cant find a ground that's bad but not sure if I found them all. Anyone have to go threw this. Thanks in advance. Sorry so long!

Run a wire from where you know it's good to the light. If it works, you know something is wrong in between.

Check your fuses - this is on a newer truck but I suspect something similar.

Check 'all' your fuses. The left and right sides are on separate fuses in my '05. Plus it sounds like you need to put in the resistors before you go any further. Going from fast blink to normal rate always seems to be resistance related. Good luck and keep us posted.
