  • Suitable for trailers, campers, caravans and boats

7-Way Trailer Junction Box Pair

This package supplies two weatherproof 7-gang junction boxes designed for trailer, camper, caravan and boat rewiring. Each unit uses colour-coded solid studs so installers can match functions quickly and keep circuits organised. The boxes suit anyone replacing aged wiring or building a new harness for towed vehicles. They are not for buyers who need a different pin count or a single-box kit.

Seven Colour-Coded Terminal Studs

The deciding specification is the seven colour-coded studs that map directly to standard trailer lighting and auxiliary circuits. This layout lets you verify each connection at a glance and avoids cross-wiring faults. If your tow vehicle or trailer uses a different pole configuration, these boxes will not match the harness.

Straightforward Bolt-On Installation

Mounting hardware includes twelve short screws, four long screws and six fasteners, while eight open and eight closed grommets seal cable entries against moisture. The multiple wire-entry design allows flexible routing without exposed splices. The only common issue is selecting the wrong grommet size for a given cable diameter, which can leave a leak path.

Questions about this item

What does the 7-way configuration mean when I wire it into my trailer?

It gives you seven colour-coded studs so each circuit — brake lights, turn signals, tail lights, reverse, auxiliary power and ground — has its own dedicated terminal, keeping the harness organised and easy to trace.

How does the junction box connect to the trailer’s existing wiring loom?

Multiple entry and exit ports let you feed wires straight in without splices exposed to weather; the included open and closed grommets seal each cable where it passes through the housing.

What mounting hardware comes in the pack for securing the box to the frame?

Twelve short screws, four long screws and six fasteners are supplied so you can bolt the box to a flat surface or a bracket on the trailer chassis.
