Video Transcript for Hopkins Wiring - Trailer Connectors - HM38138 Review

Today we're going to be taking a look at the Hopkins wiring harness with a 4-pole flat trailer end connector. The 4-way flat trailer end connector is going to plug into the connector from your vehicle to power your trailer's signal lights. Pretty simple installation. It's designed to just hard wire to the existing trailer wiring. On the connector portion right here, it's going to feature corrosion-resistant terminals, so these are very long-lasting, and it's got a nice easy-grip design, which allows for simple plugin and disconnect. The overall length of our harness is going to measure about 4 feet long. When it comes to the wiring configuration, you're white wire's going to be your ground.

Your yellow wire's going to be for your left turn brake. Green is for right turning brake, and brown is for your taillights. That's going to do it for today's look at the Hopkins wiring harness with a 4-pole flat trailer end connector.
