After buying a dometic fridge, I wanted to hookup a constant 12v supply source in the backseat area. Insert the blue sea accessory panel. Already comes pre-wired, just need to run power and ground. Powertrays actually offers a harness for this panel and it’s very well made so I opted to go with that. Ran the harness from my blue sea circuit breaker panel under the hood, into the firewall and down under all the plastic panels to the back wall. Was a bit of a pain to get the panel to mount back up. There’s a metal re-enforcement bar on the back wall that needed to be notched out a bit to let the panel sit back all the way. That and I was too lazy to pull out the goose gear seat delete lol. Took some finagling but I got it to fit and I think it came out perfect.
