Review of Hopkins Wiring HM37908


Today we're going to be taking a look at the Hopkins Wiring Harness, with a 5-pole flat vehicle end trailer connector. This connector would be located at the back of the vehicle, and it would plug into the connector from your trailer to power your trailer signal lights. It does include the reverse functions to release the brakes when backing up, so it's ideal for use with marine-type trailers equipped with surge brakes. Pretty simple installation. You just hard-wire it to the existing wiring on the vehicle. This one features corrosion-resistant terminals that are long lasting.

It's got the grip areas on the top and bottom that allow for a nice easy grip design, and this 5-pole flat vehicle end connector will work with most 4-way flat connectors. Now the harness length, I have it all bundled up, but overall it's going to measure about 5 feet long. When it comes to the wiring configuration, your white wire is your ground wire. Yellow wire is going to be for your left turn and brake. Green is for the right turn and brake. Brown is going to be for your tail lights, and then blue is going to be for your reverse lights. Now the 5-way design will also work with small utility trailers that have electric brakes.

For this type of application, the fifth wire, which would be the blue one, will need to be wired to correspond with your end cab electric brake controller. That's going to do it for today's look at the Hopkins Wiring Harness with the 5-pole flat vehicle end trailer connector.
