 Wiring Diagram


Power distribution underwent a major change in strategy in 1986.
This diagram is a work in progress based on the 1986 factory wiring diagram. If you find errors, let me know.
Tom Collins FSJ Wiring Page is a good source for looking at factory diagrams if you don't have your own copy.
Feel free to use, borrow, reprint with all the usual caveats including but not limited to; the risk is yours, not responsible for errors, and resale is prohibited.
