All rear luggage plug harnesses were the same. They had nothing to do with the fairing harness. The trunk harness is a bit of a problem in that I cannot locate the original quick disconnect plug assembly anymore. If anybody can ID a contemporary source for those plugs, please let me know. In the mean time, you might want to consider grafting in a standard modern trailer wiring harness. Put a new aluminum plate over the old plate, drill a hole in the new cover for a grommet, thread the trailer harness thru the grommet. It will be clean, sturdy and reliable.
