Ok well my suspicion is now confirmed... The dude either put in another old harness or spliced a new one in, leaving all the electrical plugs. He always struck me as really lazy so either is possible. I found a few stickers with the FD as 94, plus the part on one of the stickers is (it looks like) the old model (124 440 56 32). I did find a cracked and corroded lead back in the battery, but a spot check of the others did not show visible degradation. Looks like I need to do a new harness. Any suggestions on best way to go about this?
