American Coach: 2008 American Coach Tradition Trailer wiring ground

[Chuck Driver]

Hello forum - I am trying to confirm if my trailer wiring ground conductor is the large black conductor (probably 8 or 10 gauge). It's the only black conductor in the harness and is same gauge as the 12V power & brake controller conductors. My Ameican Coach manual is not useful in verifying this. If anyone happens to have the wiring diagram for the hitch plug and are able to post that it would be greatly appreciated.

You can use a ohm meter touch it and the trailer hitch.

I did and found another conductor with continuity to ground but one of the smaller conductors. The larger of the 2 should be the ground.

Black wire should be 12 volt white should be ground.
