I needed some additional sockets for 12v supplies, for the typical GPS, phone charger, etc.
I started off with one of these:

It worked OK, but it was gaudy and just plain old got on my nerves.
So I set out for a better solution that kept the interior of the cab looking sano. My goals were to find something good looking, built well, and cheap.
I found these on eBay:
Deluxe 12V Receptacle | eBay
They are Marinco branded and fit all my requirements, esp the price at $3.30 shipped. So I bought 5.

Next I set out looking for a good place to install them. Turns out there is a significant void on the plastic trim of the trans tunnel, up by where the heat/AC blows out. Perfect.

After I received the 12V sockets I realized that even with the significant void, space behind the trim would be at a premium. Normal spade connectors wouldn't work. So I hopped back on eBay and found some Flag Terminals. 50 for $8.25 shipped? Yes please.
50 Blue Female Flag Terminals Right Angle Electrical Connectors 16 14 Gauge | eBay

Fortunately I had already run power to the passenger side for three always hot stock light switches.

Since I have no intentions of ever sticking 8000 lights on my roof I decided it was time to lose the switches and reinstall the ash tray. Doing so allowed me to use the hot/ground wires for my sockets.

I used painters tape and covered the plastic trim. Then I made a template from cardboard and used it to mark out where to drill. Sorry, no drilling pics.

The rest is pretty straight forward. Drill the holes, install the flag terminals on the wires. Slip the socket nut over the two wires and feed the wires through the hole from the back. Hook up the sockets, push it through the hole, and tighten up the nut. Done!!!!

Pics!
Binnacle and switches out, ashtray in. Dry fit for the sockets.


The finished product, wires all tucked out of the way.


The tools. A couple 12V sockets, a 1-1/8" hole saw, flag terminals, and my template.


12Volt constant hot power. Yeah baby!!!!

 

those will come in handy especially were more stuff wont snap into a LR lighter

 

This is on my list of things to do and your installation looks great. Off to Ebay.

 

Many devices now charge via USB
There are "mobile" USB sockets you can install just like your traditional 12v sockets.
Now that my wife and I have joined the masses snd have smart phones, I'll be installing some.

 

Quite true. However, this was the closest thing I could find to looking like the others I bought, and it doesn't appear the faceplate is removable.
Then factor in one of those sockets is more than I paid for all 5 of mine and it simply wasn't a good option for me.
I figure I can snag a couple of these and still be money ahead, and still have the capability of using the socket for something with a standard cigarette stlye plug.

 

Very nice! Install looks super clean.
Where did you get the super-cool angle gauge? Looks like a quintessential Land Rover accessory!

 

Atlantic British. Got it back before your phone could do all that. The funny thing is in those really puckering spots I never remember to look at the gauge.
