Hello, I have owned my '81 for 3 years. Got it with 175K. It's has been a love/ hate relationship. Most recently I replaced the engine wiring harness. I tore it down before winter and started putting back together this spring. I had a few memory lapses but the car is now back on the road and running pretty well. Used some guesses on the vacume line routing. The Haynes service manual was little to no help for me. I would like to find a detailed diagram for all the vacume, ignition and emission controls to the engine so as to verify the correct routing and connections.
