3rd Gen seat wiring question

So, this may seem like a long and confusing question but ill try to explain it as simple as I can, and hopefully someone on here can help out.

I purchased a 2019, brand new last year, with the sport package, cloth interior. This past spring i decided to look into swapping out the cloth for leather. What I found was that it was cheaper to find full-on salvage replacement seats with leather than to have my seats skinned and re-upholstered in leather. The seats I found were in pristine condition and were a perfect fit. The only difference was the salvage seats have additional wiring for seat heating. My truck did not come with factory seat heat. So, here comes my question. Where do I find out what wiring harness I would need to connect the OEM seat heating to my truck, to utilize the already installed heating units in these new seats?

Hopefully someone here can help with this issue. Other than the addition of the seat heat plug, the seats are an exact match. Everything fits perfectly...they just have this additional plug for seat heat. All airbags, seat belt sensors, etc work perfect...just trying to see if I can utilize a feature I didnt have before.

THanks in advance.
