Step-by-step guide on wiring a 4-way trailer connector
Step 1: Gather the necessary tools and materials
Before beginning the wiring process, gather the necessary tools and materials. You will need a wire stripper, crimping tool, electrical tape, and heat shrink tubing. You will also need the 4-way trailer connector and enough electrical wire to reach from the trailer connector to the trailer lights.
Step 2: Connect the ground wire
The first wire to connect is the ground wire. Attach the white wire from the trailer connector to the trailer’s frame using a self-tapping screw.
Step 3: Connect the left turn/brake wire
The next wire to connect is the left turn/brake wire. Attach the yellow wire from the trailer connector to the left turn/brake wire on the trailer lights using a butt connector. Crimp the connector with a crimping tool and cover it with electrical tape for added protection.
Step 4: Connect the right turn/brake wire
Connect the green wire from the trailer connector to the right turn/brake wire on the trailer lights using a butt connector. Crimp the connector and cover it with electrical tape.
Step 5: Connect the taillight wire
The final wire to connect is the taillight wire. Attach the brown wire from the trailer connector to the taillight wire on the trailer lights using a butt connector. Crimp the connector and cover it with electrical tape.
Step 6: Test the trailer lights
After completing the wiring process, test the trailer lights to ensure they are functioning correctly. Turn on the vehicle’s lights and check that all the trailer lights are working properly.
