Aftermarket 7-pin harness

[TheVanillaThrilla]

Curious if anyone knows of an aftermarket 7-pin connector I can wire into my ‘21 XL. Has a factory 4-pin and I added a Class 4 hitch and hoped to add the 7 as well. Bought the attached from a vendor that I won’t name (it wasn’t Amazon) and it’s not the right fit. Returning it isn’t an option.

I think think these are called T connectors and they bolt into the factory wiring, near the drivers side rear wheel.

I’ve reached out to all of the MFG’s and have yet to find one. They all say the 15-20 are the same. I know it does not work, but they just keep saying it will.
