That would awesome, thank you. I was gonna purchase anyway and hope for the best lol

I remembered I had received a PM from mygmctruck1 explaining how to correct it.
Here it is below - all credit goes to to mygmctruck1:

On the low beam / high beam plug. The correct wiring is as follows. Looking at the back where the wires go in.

* The Black (gr) wire goes in the left slot
* The Brown / Tan wire low beam goes in the top slot
* The Green wire hi beam. Goes in the right slot

** Both of the 3 wire 3 prong plugs need this change

No change is needed with the 2 wire plug


LMC wired it this way - looking at the back.

The Brown wire is in the left slot
The Black (gr) wire is in the right slot
The Green wire is in the top center slot
