I removed all my plastic connectors and just wrapped the ends of wires around each other, put a little solder, and duct taped it. I'm thinking maybe it's the D3 connector but wasn't able to remember how to "unclamp" it.

And it turns out, the extra wire I bought is this thick solid type (think barbed wire with rubber coating) rather than the typical frayed stuff you see in electronics - that doesn't matter does it?

Any bare metal under the dash will make a good ground.

The only potential issue with solid instead of stranded wire is flexibility. Solid wire can't be flexed too much or it will break.
