I have a 81' Mini Cruiser that was born with a diesel and at some point in its life grew a 20r. When the transplant took place it was in a rather "creative" fashion. My ignition switch, or so I believe it is, is running my carb, fuel pump, distributor cap, and alternator. All of them are wired into this one little wire. There are plenty of other wires here in this harness but I have no idea what they are or where to get a new harness. Any advise is welcome.
