I need some tail light wiring help, please....

[robby5323]

Working on the project - 1965 SWB Fleetside. I am trying to get the tail lights working with blinkers, brake lights, etc... Over the years, someone did a hack job on the rear taillight harness and there are splices of different wire everywhere. Here is what I have at the plug for the harness:

1. Black/Yellow wire lead
2. Black lead
3. Dark Green lead
4. Yellow lead

Can anyone tell me where or how each lead needs to go...? I was able to play around with it a little yesterday and got the brake lights, running lights, and signal lights working UNTIL you turn on the headlights, then the blinkers just hold and do not blink. The plug has had the wires spliced off with only about 3 or 4 inches on them, so the original wire colors are all gone...

Appreciate any help...
