2000 ac 64 wiring issues?

Does anybody have or know where I can get a wiring diagram for a 2000 ac 64. I am trying to track down electrical gremlins and having no luck. A bigger help would be if anybody has any ideas of where to start. Most of the issues are head light and blinker related with extension to the gauge cluster. i am now also having injector issues and think I have it tracked down to either the harness or injector driver.

Thanks Andy
