Theres been a lot of issues with the 12 pin plugs when running chargers and fridges through them and many people are opting to simply seperate the circuits and run anderson plugs for piece of mind.
Try somewhere like the Home of 12v shop at Pooraka for a pre made anderson plug circuit which can be bought to suit the vehicle you drive.
I have a BF wagon and i simply told them what i had and they supplied me with a complete kit to install myself with everything required.
I also bought a special trailer plug from Autobahn which has a 7 pin flat plug for trailer wiring and a piggybacked anderson plug so it all looks neat and simple.
The only other thing you'll need is a Redarc isolator which arent cheap.
