I have to say, you cannot have too many 12v plugs in your rig. That said, I have had two Marinco plugs in the rear wired to my Aux battery/household circuits for some time.

This summer while camping, I found out that with my fridge, and trying to keep all the family electronics charged it was time to engineer a better setup.

So, I looked at some offerings for pre-built panels from OZ, but decided to build my own.

Here was the basic design that I worked out. All of the items are marine-grade.

  • Dual Battery Gauge - from Topo - wired to both main and aux
  • Two standard "ciga" style sockets - the Marinco's I already had. Each fed by dedicated 10ga wires direct to panel
  • One dedicated Topo Engel plug (waiting for this one still, was sent the wrong plug). Also dedicated 10ga wires
  • One BlueSea dual 2.1amp USB to charge iPhones, iPad, and Kindle, you name it
  • Hazard Switch repurposed and relabeled to turn the gauge and USB on and off
  • Two marine fuse plugs for the gauge
The hazard switch was perfect, as it has two separate circuits which switch on and off, allowing both banks to be monitored by the gauge, and turned off accordingly. It also lets me turn off the USB, which otherwise would always be on.

The panel itself was a piece of $1 scrap of black textured ABS from TAP Plastics. I drilled the holes undersized, and filed them to exact fit for the plugs. I used blue tape on the face to work on my layout, then drilled and used the dremel to make it work.

Removed the ash tray, as it was never used, and never would be used. Cut a nice big square hole in the panel, then attached the new panel to the truck using four nut-serts which I have left over from my roof rack.

Here are a few pics. :grinpimp:

Both banks charging nicely, but still need the Engel plug

Just a few wires behind the curtain! Plus the pure-sine inverter hiding below the ARB fit kit.

Oooooh, daddy LIKES!
 
Looks great. nice work. very clean
 
Looks great, what route did you use from the front to the rear of the rig?
 
Very nice! I was just working on my rear aux wiring today. You are a ways ahead of me. Excellent.

Started at the Aux battery with an 80A circuit breaker, then ran the dedicated Pos and Neg cables through the PS firewall grommet (plenty of open places to send through), then directly down the PS side of the truck in the wiring channel which is under the kick panels. Easy to do, actually.

Engel plug arrived tonight, so buttoned the whole project up.

Fridge works, gauge works, switch works, USB works, and I am pretty pleased with the results.

Now thinking about setting up another Anderson Plug, this time wired to the Aux, and out the rear for use with a camping light, a work light, and also to make an "extension" cord for the Engel, should I wish to have it outside of the truck...will save that for another thread.

Clean. I like it. Will shamelessly copy some of it, but on the DS. Thanks. :)
 
Very clean as usual, can't wait to see your other project finished. Did you add a switch near the aux battery too?
 
Aux Power panel looks awesome. May need to look into doing something similar.


Where does one source this dedicated Engle Plug? I am not seeing it on their web site.
 
Subscribed.

I'll definitely be ruthlessly and shamelessly stealing this idea for my own rig.

DCJoules is on both eBay and Amazon. They import the Topo stuff from OZ, which is who makes the Engel specific socket and gauge I used. It is an excellent setup for our use, since you unscrew the tip of the normal 12v plug and then screw that into the Engel socket. No way that puppy is coming loose.

Yes, the 80A breaker right at the Aux battery which serves as a master off-switch.

No worries about others making use of ideas on Mud, pretty much that is what this site is all about. ;)
