I would run a circuit from your fuse board at the back to an Anderson Plug under the console fridge and then use an Anderson plug off your fridge. This will give you a fused circuit and flexibility if you ever have to take it out. If you can also put an inline fuse in your new lead off the fridge then you are double protected and take protection with the fridge if you ever take to another car.

you need to join the lead to the new circuit anyway so you might as well just use an Anderson Plug for that joint.
