Cruise Control Does not work when towing 5th wheen

Diagrams that I couldn't get to upload before. Notice all of the vacuum/vent solenoids on the speed control servo?

Now the exterior light wiring of the OPs 2004 that show the trailer plug connections. The diagram is so large that in order to capture a clear picture, I had to blow it up and cut it in half.





Can anyone recommend a better photo uploading site? Photobucket has become a pain the backside in the last year or two.
