Steering column connector

Ok, go easy on me here. I can follow a schematic, solder and such but my knowledge of electrical hardware is pretty nonexistent.

For a 12ga wire it appears I need a minimum of 20a capability connector. A 0.093 molex connector is good to 14ga wire from what I see, I haven’t seen anything larger than that. The connector under the column looks like a Molex connector. Any chance I could be that lucky? So are larger pins available? If not is there something like a Delphi metri-pack 150 that can carry the load safely? And does someone sell the complete connector, all I see are housings, pins etc to build your own.
