Welcome to the forum & irv2.
Mostly a short distribution of wiring in most Owners Guides.
Here is one for a
2001 MACA. 2000 UNAVAILABLE Wiring,plumbing and gas line at end of link.
Here is a
brochure with weights, tank sizes etc,etc.
If you look closely at wiring you may see print to tell you what wire is for and where it goes.
If you need any further help for what ever your trying to trace just give us information.
Enjoy the forums.
