Bill, dont have a wiring diagram, and for some stupid reason only have pick up coil resistance for the 88, which is 5.2Kohms to 5.9Kohms, between W/G and W/R wires. i have every other bloody year but not the one you need. I hope this at least helps a bit. By the way, the 89 pick up coil is double the resistances, same color code so they must be different, i would have thought they would be the same.
