try your international truck dealer for a chassis/engine diagram, the coach is body mfg dependant as well as whoever added whatever over the years.
be sure to tag and document your wat thu the coach wiring as you go for reference in the future.

Thanks for the info.
Not sure what you mean by "wat thu the coach".

My understanding was:
Be sure to tag [the wires] and document your [way through] the coach wiring as you go[,] for future reference ...

hex must have dislexic fingers like me, his interpretation is correct, document your way thru the process of repairs for later reference.
