Adding 12V to rear for fridge

[Jeepless]

Hello,

I have a question regarding adding a dedicated 12V outlet for my Dometic fridge in the rear of the Jeep JL with Aux switch option. I have purchased and mounted the two dedicated 12V outlets (Dometic Hardwire Kit) to the rear, underneath the driver side rear seatbelt mechanism. I was planning on running the wiring tomorrow and originally was going to go from the battery, across the frame, through the drivers side firewall to the outlets. I have a few questions:

1. Do I need to be worried about parasitic draw, going this route?
2. Instead, can I connect to the battery wire in the aux bundle (under the passenger footwell) and across and to the rear of the vehicle? If I was worried or wanted the outlet to only be on with the ignition, could I wire it the same way but connected to the ignition wire in the aux bundle instead of the batter wire?

I don't have any free aux switches, btw.

Thank you for the help and time. I appreciate it

picture to make it a little more exciting… sorta, sorta not exciting at all actually.

1) As long as there is nothing plugged into the 12V outlets and they don't have any LED power indicators built in there should be no parasitic draw.

2) You could connect to the Aux bundle wiring however both the Battery and Ignition Aux wires are fused smaller than the other Aux circuits, at only 10 amps.
Note that the existing 12V receptacle in the back is fused for 20A and the owners manual says 13A load maximum. The vehicle schematics show that the wire gauge is also half for those two Aux circuits, so it might be best just to connect your own fused wiring to the battery

Thank you for the reply. I should have thought about that, but the idea popped in my head and I almost immediately thought to ask. Glad I did! I will continue with the original plan to connect directly to the battery and negative and run it through the firewall!

Thank you again!

Running the wire is super easy. It can be done in about 15 minutes. This is how I did it

Sweet! I’ll knock that out with the new diff covers when I get off work in three hours! Thanks for the video, that was the route I was going to wire it

I ran an air compressor to the tail light and used a ground that was back there for the other 12v plug. That’s one less wire to get all the way up front.
