Video Transcript for Brophy Wiring - Trailer Connectors - R7CB Review

Speaker 1: Today, we're taking a look at the Brophy Replacement 7-pole Trailer Connector Socket for the Vehicle End. This is used, typically, for commercial trucks and trailers. It does come with brass contact points for better conductivity. And, as you can see, it's a seven round pin connector. The housing is a durable ABS plastic construction that's black in color. And it does feature the nice frame loaded lid, which keeps the contacts protected when nothings connected.

The connections on the back are easy to make with the included screws and color coded indicators. So, you don't actually see the color. But on each terminal or connection point, it says what color wire gets connected there.So, right here, it says 4 red, 5 green, 6 brown, 7 white . or 1 white, 2 black, 3 yellow, and then you got the 7 blue right here in the center. Loosen up the screws.

Place the wire in. Tighten the screw down. And really, that's all there is to it. It's a really nice design. Very easy to use.

Very easy to get everything connected, as it should be. And you have pre drill mount holes right here. These are elongated. These mount holes are separated on center by three inches. Mounting hardware not included.

That's gonna do it for today's look at the Brophy Replacement 7-pol Trailer Connector Socket for the Vehicle End.

As a dielectric grease, it's not a conductor, which keeps your connections safe from interfering with each other. I've linked to a video review of this grease for you to...

  • Comparing the Wesbar LED and Incandescent Agriculture Trailer Light Kits
    The price difference between The Wesbar LED Light kit # 54003-041 and the Wesbar Incandescent Light Kit # W002676 is due to the cost of producing LED lights versus incandescent light bulbs. LED light are quite a bit more expensive to make than incandescent lights. That being said, LED lights will last longer and use less power than their incandescent counter parts, so I do suggest going with the LED option. It should be noted that both the LED # 54003-041 and Incandescent # W002676 will...

  • How to Troubleshoot a Trailer Connector Without Power
    If the trailer connector at the rear of your 1998 Ford F-150 is not receiving power, you will first want to check inside the connector for any dirt or debris.
