Blue Bar 12 Pin to 7 Pin Trailer Adaptor + 50A Anderson

One lead that does two jobs

Towing a caravan or camper fitted with a 12-pin flat plug, but your tow vehicle only has a 7-pin flat socket? This Blue Bar adaptor solves it. It carries your trailer’s lighting and signal circuits straight through from the 12-pin to the 7-pin connection, while a separate 50A Anderson connector gives you a dedicated heavy-duty feed to run a 12V fridge or auxiliary load from your vehicle’s fridge power lead.

No more juggling mismatched plugs or losing fridge power on the road — one tidy, purpose-built lead handles both.

Why choose this adaptor

• Genuine Trailer Vision plugs — heavy-duty nylon housings with the Spring Terminal System (STS) stainless steel contacts that stay tensioned for a reliable connection trip after trip, plus gland nuts that keep dust and moisture out.
• Separate 50A Anderson connector — a dedicated high-current path to power your 12V fridge or aux load, kept independent of your lighting circuits.
• Protective sheathing on every cable — heat- and abrasion-resistant conduit that stands up to engine bays, drawbars and corrugated outback roads.
• Made to any length — tell us the length you need and we’ll build it to suit your setup. No leads that are too short, and no tangled excess.
• Handmade in Australia — manufactured by hand in our Brisbane workshop, not mass-produced overseas.

How you’ll use it

1. Plug the 12-pin end into your caravan or trailer.
2. Plug the 7-pin end into your tow vehicle’s 7-pin flat socket — your trailer lights, indicators and brake signals carry across.
3. Connect the 50A Anderson to your fridge power lead to run your 12V fridge.

Built to spec. Made for the track.

Every Blue Bar lead is assembled by hand here in Brisbane, so you get a product built for Australian touring conditions and made to fit your rig — not a one-size-fits-all import. Need a custom length or a tweak to suit your setup? Just get in touch.

Please note — wiring configuration: On the 12-pin plug, only the top row of 7 pins is wired, which carries the trailer lighting circuits (tail lights, indicators and brake signals).

The bottom row of 5 high-current pins is not wired.

High-current power for your fridge or auxiliary load is delivered through the separate 50A Anderson connector instead, keeping your lighting and power circuits cleanly separated.
