John,

I understand, man, electrical drawings can be complex. I could not do my job without those drawings. You can tame the beast a bit in several ways.
* Copy the wiring diagram to make a working copy. Enlarge the copy, if possible.
* Use highlight markers (of various colors) to color along each wire that you want to trace, on your working copy. Don't mark up your original drawing.
* Use index cards (or similar) to block out the parts of the drawing that you do not want to see, so all you see is the correct wire, above the card edges. This also helps when a wire zig-zags across the drawing.
* Make written notes of any connectors or Pin Numbers that you find along your wire.
* Find connector locations (maybe from other sources) so you will know where to check them.

Happy hunting. I want to say thanks again to the Injuneer for the help he has give me in the past.

 

The connector locations are shown on 3D harness routing diagrams in the factory service manual. You've essentially outlined the procedure I use. Print “current” page from factory manual pdf, use colored markers to highlight the circuit of interest. Make a notation of connector, splice, and pass throughs for the circuit. Note PIN numbers for each wire of interest. Look them up in the 201 and 202 sections of the factory service manual.

If he follows up with my directions I'll give him the page numbers in the manual so he can locate them. Unfortunately the 1995 manual copy is missing a lot of those pages, so I have to reference the 1994 manual. And Shoebox has the 1995 pages for the turn/brake circuits. The only differences I have noticed is the size of the wire of interest being slightly larger. But I think that is because they tied in additional destinations for the connections to the optional traction control which was added in 1995. (It was supposed to be available in 1994, but was delayed for some reason).
