4 Prong 5 Wire Trailer Harness. Some trailer wiring kits include the connectors and supplies needed for installation, but some don't. You'll still need to buy a heat gun and crimping tool separately.
I do not see their purpose. This style Trailer Connector is most widely used for boat and utility trailers without electric brakes. Doesn't Include relay, Only Relay Socket !
Safely and properly apply the load from the trailer lighting to the battery & not the rest of the bike's wiring relays/fuses.
I am in need of the wire harness pig tail that has the flat four prong plug.
Some trailer wiring kits include the connectors and supplies needed for installation, but some don't. If you're talking about the receptacle next to the hitch that your trailer plugs into - it depends. Rather than installing the turn signal converter inside the panel behind the spare, it seems like I could wire the brown wire to the red trailer lights and the yellow and green turn signal wires to.
