At the tail lights on my 64 Ranchero I have isolated L turn wire R turn wire Brake wire and running wire. All on drivers side. Only the R turn wire is runs across to the passenger side. There are 2 other wires cut at both ends that also run from R to L tail lights. Can you tell me how all of this should be hooked up? None of the wires are connected. looks like somebody just cut all the wire ends? Could not figure out the configuration with a double filament bulb. Any help would be great.
