How to Install the Hopkins Endurance 5-Way Flat Trailer Connector


Today on our boat trailer well be installing the Hopkins Endurance five way flat trailer connector, part number HM47910. Well be adding this to an existing four flat setup and an added brake solenoid actuator. With the trailer already equipped with a four pole connector, well go ahead and cut it off. Well strip back the four wires and add a butt connector to each end. Now well go ahead and bring in the five flat trailer connector. Well match the color for color for the white, brown, yellow and green with the four flat that was originally equipped with the trailer.

Then well take one side of the solenoid wire and add a butt connector. Next well add an extension wire to the solenoid wire with a butt connector. This will help with connecting to the blue wire on the five pole. Now with all our connections made and using a special butt connector that can be heated to heat shrink around the insulation portion of the wire, well go ahead and use our heat gun to heat up the butt connectors next. Once we have all the butt connectors heated and the wires shrunk well go ahead and let that go, as it will need to cool.

Next well take the second wire coming from our solenoid, and this will be our ground wire for the solenoid. Well add a ring terminal and then using a self-tapping screw secure the ring terminal to the frame of the trailer. Using the heat shrinkable butt connectors along with the additional black electrical tape will help keep out any dust, dirt, debris, and especially moisture for our boat trailer application off of our connection points.With everything taped up were now ready to hit the road. That does it for the install of the Hopkins Endurance five flat trailer connector, part number HM7910 on our boat trailer. .
