Should Junction Box be Used For Adding 7-Way & Wiring to Trailer  


1989 6x16 flatbed trailer, it needs the complete wiring harness 7-way. Should I go with a junction box? Im also planning on adding a brake on the front axle and replacing the existing ones. So treat me like a newbie.

For adding wiring and a 7-way to your trailer, a junction box and 7-way connector is absolutely the way to go, because it is the easiest way to connect your wiring. The best option for that is the following:

- Junction Box - 7 Terminal # 3375601100

- 7-Way RV Style Connector - Trailer End 6 ' Long # HM20086 or 8' Long # H20046

If you need added components for install such as a wire tool, zip ties, circuit tester, butt connectors and more, you may want to consider getting that in one package with the Hopkins Deluxe Trailer Wiring Installation Kit # HM51020.

And if you need the actual brake wire, you can get that by the foot with Deka Jacketed 2 Wire, 10 Gauge Brake Wire # 10-2-1.
