ARB Fridge Wiring Kit

The ARB Fridge Wiring Kit (10900027) hardwires a 12V fridge/freezer straight to your battery. It's 20 ft (6 m) of double-insulated 8 AWG auto cable, pre-assembled with an in-line fuse and 8 mm (5/16 in) ring eyelets that bolt to standard battery terminals. The kit also includes an ARB screw-in surface-mount socket, so it's a complete battery-to-plug solution rather than just a length of wire.

Heavy 8 AWG cable is the whole point. A factory accessory socket and its thin wiring drop voltage under a compressor load, which makes a fridge cycle harder and can trip its low-voltage cutoff. A dedicated run on this gauge keeps the fridge fed at full voltage. The two 1/4 in side-entry quick-connect terminals ship loose on purpose: you trim the cable to your actual run, then solder them on, so the line is no longer than it needs to be. The socket's rear terminals are marked + and - for correct polarity.

The battery end and the in-line fuse come pre-assembled; the only on-site work is trimming to length and soldering the two socket terminals. With 20 ft of cable you have room to route from an engine-bay battery back to a rear cargo area or drawer where the fridge actually lives.
