Backup lights

[nacman]

Driver's side backup light issue. If I run jumper wire from black to black and light green to light green it works. Plug in the harness and it doesn't work. I tried to bend connection on the truck side Plug in and added some stranded wire to get a better connection. Didn't help. Truck also has hyper flash and no led bulbs. Everything else seems to be working. Brake lights, running lights, blinkers...other than the hyper flash when blinkers are on.

Have you tried swapping the driver and passenger boards to determine if it is a board or connector problem?
The connector is fairly robust and the boards are known to flake out.

If you have a multimeter handy, you can check the board for continuity and resistance based on the diagram below.

If you need a new rear connector, you can cut off the old one and install this pigtail with solder or crimps.

If you need an entire harness, you could make one yourself or pick one up at a salvage yard.
I just so happened to pick up a rear harness at a salvage yard the other day and took measurements of leg lengths and cable colors.
