Ground locations...

Now I was already planning on adding a ground strap to the fifth wheel to help with the trailer lights, but looking at the big picture, it looks as if I'm also having problems with inadequate grounds on the tractor. I already ordered a set of crimpers, I'll be replacing my weathered cables with welding cable, and ensuring there is a good ground to both the block and the frame.

What I'm curious about is if anyone knows where I can find all of the little grounds are at..

I don't know if you ever checked but the socket that your trailer pigtail goes in on the truck side could be corroded internally. I had a similar problem with my trailer lights messing up in weird ways. I pulled the pigtail out and looked at the socket. It was corroded green all the way through to the back side inside the cab. There is also a ground cable that attached directly to the backside of the mounting bolt inside the cab that was rusted. I cleaned that up and replace the socket and now my trailer lights are on bright and don't do weird things. It may be worth a check. I also installed mine filled with Dielectric grease then sealed my pigtail into it with a silicone sealant bead. To keep water and dirt out.
