Hey all,

We have a trip coming up next week to Flagstaff and am looking for a quick way to bring power to my power pack in the back of the PW.

Could I tap off the trailer charge wire off the back of the seven way plug. Add a fuse and a 12v outlet and call it a day?

Not looking to power a ton of stuff, just a fridge and cell phone charger.

Thoughts?

Other option was to add a powered fuse box under the hood and running cable to the rear. Not really wanting to get that complicated though.

No.

If you want power back there, a fridge and say 2.5 amps for a tablet (let’s just say 5-6 amps total), do it right the first time. Run some 8 gauge wire (fused at the battery) back there along the frame rail and install a proper Blue Sea type 12v plug and one of their high power USB’s.

Done son. You’ll be glad you did :D

I was reading your mind already. Just got back from the Depot with 25 ft of red and 25ft of black.

I have a 6 fuse Blue Sea box that I'll throw in. Just trying to figure out what relay I need to "switch" on the the fuse box.

Make sure you fuse it up front AT the battery!

I’d recommend a simple battery cutoff switch to control power to your Blue Seas fuse block. Simple and durable.

Had to mount to the factory fuse box cover as I can't seem to find a pre-fab'd base. I'll make one up in the next few weeks but this will get me by until then.

Waiting for the 12v plugs for the bed to show up tomorrow but finished the relay and fuse box. Will run 8 ga. Wire to the rear tomorrow as well as mount the plugs.

30amp relay off of a 30amp main fuse. Will use 20amp fuse to feed the rear. Can't drill into the fuse box cover as the legend is on the other side. Used 3m tape and Plastic weld for now. Again until I source a proper plate to mount everything.

Would like to also source a relay that has screw terminals in lieu of spade connections, any one have a source for something like that?

Ran 8ga. wire (oil and gas resistant). Damn I'm getting old, that absolutely was a pain I'm the butt.

Cut in the waterproof panel. Up and running, just need a better set up under the hood. Held up all the way to work no problems, but it looks hooky.
