I have the Haynes repair manual 1987-2003 Jeep Wrangler with all of the schematics. Which wiring scematics do you need and maybe I can scan/email the pages, if this legal? Or can maybe answer questions you may have, keeping in mind I am NOT a mechanic but I can read plans/schematics

Check this on 1987 Jeep Wrangler 4.2 liter L6 VIN "C" 2-bbl
Ignition timing is a measurement, in degrees of crankshaft rotation, of the point at which each cylinder's spark plug fires. It is normally listed as a specification in degrees before or after Top Dead Center (TDC) of the compression stroke.
On the 4.2L engine, the timing can be adjusted by turning the distributor in the engine. A graduated timing degree scale located on the timing case cover is used for reference when timing the ignition system. A milled index notch in the vibration damper is used to align the No. 1 cylinder ignition position of the crankshaft with the correct timing degree mark on the graduated scale.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using Fixya, and have a nice day.
