If I could post pictures, I could be more help....
You can buy a hitch many places..Wingstuff and other site sponsors.
Same thing for a plug and play wiring harness.

I bought both my hitch and wiring harness as a plug and play install from Bushtec. But I think the harness is Electrical connection.

Anyway, our sponsors offer up everything needed. Not difficult to install.

If you lived near me, I need another project.
I finally have my trailer 2 doNE and I'm extremely pleased with the result. PM me and I can email you a better answer.

Start here for a hitch.

And here for a wiring harness.

The 4 wire trailer plugs will come with your trailer, you just wire the harness color to color on your trailer plugs.
