Grounding a 4-Way Wishbone Trailer Connector
Question:
First time through on this. This four plug harness does not have a ground wire to be grounded to the trailer? Does that mean its grounded through the wire to the plug on the truck and utilizes that ground? Again. First time doing this.

The 4-way harness you looked at, part # A25W2GWB, has a ground wire. It's the white wire which is kind of hard to see in the pictures.
This is a wishbone 4-way so there are two brown wires for running lights; one for each side of the trailer. Then the green wire is brake lights and the turn signals for the right side and the yellow wire is brake lights and turn signal for the left side.
