My truck has developed a short affecting the entire rear lights,ie: signal, tail lights, brake lights ( of course). The connections are all sound, in fact the backup lights do work.
I wonder if anyone has a wiring diagram that they might fax to me so that the trouble shooting will be made easier and intelligently.
I would appreciate this document so that I can work the issue tomorrow.

Thank you in advance.

Larry, I want to thank you publicly for the schematics you sent me. I also received a set of electrical schematic drawings from R. Smith and with the combination was able to determine the root cause.
I found, much to my satisfaction, the short, not in the harness, but in the trailer/camper harness connector. This apparently had been crushed during the replacement of the rear bumper required after the truck had met an oak tree.
Thank you for your speedy response. I hope that I may be as helpful to someone in need of aid.
I am here again to report what the root cause of the short and the resulting damage.
I had earlier indicated the problem source as the camper connector, however after checking the crushed connector, I found no electrical damage but notice a couple of wires that were apparently not connected to anything. These disconnected wires happen to be the result of the previous owner having U-Haul make one of their wondrous connections into the brake/turnsignal, running light and remote battery charging wire with one of those splicing devices that they are so apt to use. The wire that had completely been sawed through happened to be the always hot camper battery charging wire which ultimately made contact with the bumper bracket.
To make matters worse, the overload on the flasher unit caused the heater to burn out and remain in close position.
Nice, huh, Had fun tracing and correcting but that would not have been possible if it wasn't for the help of the aforementioned members.
