12-Pin Trailer Plug: Hot Wire Upgrade – Towbar Mounted (Supply & Fit)
Standard factory-installed 12-pin plugs often use thin-gauge wiring that struggles to power modern caravan fridges or charging circuits. Our 12-Pin Hot Wire Upgrade replaces or supplements factory wiring with heavy-duty cabling, ensuring your 3-way fridge stays cold and your internal lights stay bright throughout your journey.
At Offgrid Touring, we specialize in "fixing" inadequate factory towing looms by installing dedicated high-current circuits designed for the demands of modern touring.
The "Melting" Problem
Standard wiring often causes the 12-pin plug to overheat because the wire is too small for the current draw. We upgrade these critical pins:
What’s Included
- High-Current Cabling: 6mm or 8B&S heavy-duty automotive wiring run from the vehicle battery.
- 12-Pin Plug Supply: High-quality, durable 12-pin male or female plug (if required).
- Ignition Triggering (Optional): Integration with an ignition-switched relay to ensure your fridge only runs while the engine is on.
- Circuit Protection: Independent fusing for both the permanent power and fridge circuits.
