I would suggest you purchase a shop manual for your car. Faxon Auto Literature is one place to look for these. There are other sources as well. It will have all of the data plate decode information you need as well as a complete electrical schematic.
Send me an email at email@example.com, and I’ll scan the parts book page that shows the codes for the patent plate and the wiring diagrams from the shop manual. Unfortunately, there is no master schematic, but each system has an individual plate.
