Electrical Help

I’m planning on putting an “always hot” cigarette lighter in the back of the center console. I’m mechanically inclined but electrical stuff is my downfall.

What gauge wire is best for this? I will be running a fridge and charging a solar charger.

I plan to just put an inline fuse.

Am I missing anything?

 

What is the amp draw of the fridge?

 

The ARB hard wiring kit (

There are plenty of calculators/charts online that detail ideal wire gauge vs. length at specific voltages like https://www.engineeringtoolbox.com/12-volt-wire-loss-chart-d_1689.html

I ran 12 Ga to the rear of my center console on my double cab wired directly to my aux battery under the hood for my fridge. Notably, the left grommet on the firewall near the ABS unit is not too difficult to work with, but I would recommend using something like a wire insertion tool (used with an adequate lubricant) to help make the process a little easier -- like
