When the two connectors are joined the ground has continuity.

I think I may have stated my problem a little hastily, and somewhat (VERY) embarrassed When I tested the lights in the beginning, I just connected the wiring harness from trailer to the truck, I never had the trailer hitch connected to the truck hitch ball as if I was towing.

In your Post you stated 'I have seen wiring set up that relies on the trailer ball to provide continuity for the ground', this may be the reason?
Going to actually attach trailer to truck hitch/ball and see if it resolves my issue. If it does, I feel like such a dumby !

Will report back with results....
