Stuart, believe it or not I have those tools but never got the hang of using them except for something simple like current to the tail lights but dont know to fix this problem:
Lights work back and front -- signal works also when lights are off but only right side works with lights on--so everything works but not togather.
Brian, I think I have the switch for neutral and back up wired correctly but have a problem with the Ign. and solinoid terminals.
Where can I get new connecters to replace the old ones?
