Need diagram of wireing on Freightliner XC Ignition switch

We have a 2007 Freightliner XCR chassis and are having a problem with the electrical system. The jacks, rear camera and screen and the dash AC have all stopped working. There may be other things too....

Class A makers do NOT run the items thru the Ignition switch. They install a separate solenoid that IS powered by the Ignition switch to power hi draw and extra appliances. Especially the ones you mentioned, which almost all use that separate Solenoid. The fact they were intermitant then failed shows it is this extra solenoid. IT IS NOT FRTLINER INSTALLED OR FRTLINER WIRING. It is the RV maker wiring. Doug
