wouldnt you want to hook it to the passenger side, as per the diagram posted at the top?
I bought a connector yesterday, oem ford part to connect a trailer. On the diagram it came with it said to plug into drivers side, which i did. The only thing coming out of the drivers side was the lights for the licence plate, so i disconnected those and ran it anyways. I have no running lights, left signal does nothing, right signal = hazards and brake lights work. I will try looking for a connection on the passenger side as per the diagram, hopefully I dont need new relays and connectors.
