I've got a Chilton for our trucks that has the wiring diagrams in the back, fortunately by trade, I'm an electrician and know how to read them. I'll check it out per the manual to see if we're missing anything and I'll get back with you.

OK, according to Chilton, that line is fed from Fuse 7 (15 amp) in the power dist. box. It then goes to the Main Light Switch (Tan/Wht is the line, and Brn is the load; essentially to the lights). I would check at the Main Light Switch to make sure that you don't have a loose connection or a bad switch.
The book also shows a multi function switch (inwhich case I have to do more digging to find), but it also feeds some of these lights and the instrument panel turn signals. If you have those lights, then I would seriously doubt that your problem is here.
Hope this helps you some.

I don't think it is in the switch as i have part of the lights working. the only lights that have no power is the park lights. I also have power to the trailer plug. I am going to pull the four lights and housings to check for burnt wires. Thanks for all the imput

just an update. I drove the truck to the auto electric shop, and he thought it was in the fuse block. Now he has the truck to a point that it will not even turn over or attempt to start. now i have to have the truck towed to another garage. I guess he may be a electric expert, but knows nothing about the diesel. Lesson is make sure you take your truck to a reliable diesel shop.
