How to Wire an EZ Loader Trailerby Bob White
Your EZ Loader trailer is subjected to regular dips in the lake that can corrode its electrical system. For this reason, it is wise to inspect its wiring system for cracked insulation or corroded terminals. When launching the boat, you should disconnect the trailer's wiring harness to avoid the chance of shorting a light bulb. Your EZ Loader uses a four-way trailer harness that provides power for signal, marker and brake lights. Replacing this harness is a simple process once you know where the wires go.
Remove the existing wiring harness from the trailer by cutting the cable ties that fasten it to the frame and pulling apart the connections at the lights.
Fasten the wiring harness's four-way connector to the trailer tongue with cable ties. Leave enough length to make it to the tow vehicle's connector, but not to much that the wires will drag on the ground.
Back off the grounding screw on the trailer's tongue and slide the white wire's ring terminal underneath. Tighten the screw back down. It is important that this connection be made to bare metal. Remove any corrosion with sand paper if necessary.
Run the brown wire on the harness to each marker light. Apply waterproof electrical grease to each connection and push together. The grease will prevent the trailer's electrical connections from corroding.
Run the yellow and green wire combo to the back left of the trailer and connect it to the left side light at the rear of the trailer.
Run the green and brown wire combo to the back right of the trailer and connect it to the right side light at the rear of the trailer.
Run the yellow wire to the left side of the trailer and connect it to the second light in from the left side of the rear of the trailer.
Run the green wire to the right side of the trailer and connect it to the second light in from the right side of the rear of the trailer.
Fasten all loose wires to the frame of the trailer with cable ties.
