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

Hi. I attempted to place an order for the harness but the site said your inbox was full. Is there another way I could get in contact with you guys. Thanks.
