I'm going to be installing this SubThump box and amp combo, and I would like to purchase a harness from LLJ Customs.

I've reached out to LLJ customs twice and they haven't gotten back to me. Can you guys help me with choosing the correct options for the harness? It's for a 2020 Silverado LT, 8" without Bose.
Here's the link to the harness. https://lljcustoms.com/store/ols/products/2014-2018-gm-t-harness-for-8-screens-without-bose-1418gm8
First option: Line Output Converter
I already know I want the LC2i with the bass knob
Second Option: Vehicle Connector Color
I don't know which connector they're talking about and how to find the color
Third Option: Harness Length
I don't know where this harness plugs in, so I don't know how long I need the harness to be to get to under the rear seat
Fourth Option: RCA Cables
I have no idea if I need these
Fifth Option: Extended Amp Turn On Wire
Again..no idea where this is plugging into in the car or if I need it extended
And finally, should I just skip the harness? What's it actually doing? Can I just do the wiring myself if I'm comfortable with soldering
