IPCW LED taillight users - backup bulb and harness?

Thanks - I’m going to try to find a Dakota at a wrecking yard and see if I can’t just cut the harness out.

In case you wanted to buy new sockets and solder into the SLC harness. I'm pretty sure this is same ones I used when I was playing with retrofitting a stock tail light. It's for a single or dual filament bulb, I'd just tie the red and green together for the positive and will be good for either 3156 or 3157 bulb for the reverse light.
