D2 rear 12 volt outlet.

is there any way to make this an "always on"
power supply?

If you're thinking of running a fridge from it, it's better to have a more secure plug (Hella marine, Engel, etc) that gives a positive fit and won't rattle free.

Therefore you just wire it in and back to the battery (with a fuse).

Otherwise you should be able to trace the wire back and move it to a fused link directly to the battery (Check the RAVE CD)

I guess you can direct wire the plug it to the battery.


Making assumptions about your question though...
Assuming its for a fridge also, its a usable connection but a poor connection. I found that using this didn't allow the fridge to operate as efficiently as it could, with the temp setting set at 70-100%. Also, the connection isn't reliable. It'll work fine for a while, but the internals of the plugs degrade quickly (over a week or so) until the undervoltage faults trigger and the fridge turns off. The fix for this is a new plug. The cig lighter plugs also disconnect from vibrations.

So far I've found the marine plugs that screw together work really well.

agree with all the above. I had a problem with voltage drop using the LR one for my fridge (Waeco 50)so had another put in using 6mm cable. Problem solved :) It also means I get to use the original fitting to run to my inverter to charge batteries, run the laptop etc.

hmm, ok. can see the connector is not great,,

how about the power supply that lives behind the drivers side tail lamp?
Its always on,, but is it big enough?

If it's for an Engel, the Engel plug really doen't workj well in a ciggy lighter socket. ]

The end of the Engel unscrews ans leaves a 2-prong plug. ]

The genuine Engel socket accepts this plug. To make it even better, the Engel fridge plug screws into the socket to lock it in place.

Disadvantage? Bloody pricey!

Not disco II, but I use a 32 volt DC socket in the back and wired to the battery with fuse. These are similar to those used on 240 volt AC extension leads, but have 2 pins in a T pattern.

Others that I like are Anderson plugs and sockets.

I use a 12 volt flouro camp light that I plug into the trailer socket. Ran a 12 +ve wire to an unused pin in the socket. Fit a trailer plug to the lead on the light.

Yes, they are good and worth installing at least one in a car. They are damn exxy in comparison to a standard 240V GPO.

I also use the 32V DC plug, 2 in fact left and right side for 2 fridges. Also have 2 Anderson plugs 1 internal (location left vent) and one external under bumper.

The Anderson plugs are 10mm cable and the DC plugs 6mm.

i use anderson plugs, 2 at the rear, 1 internal 1 external, 1 external at the front and have them all wired on 13sqmm cored cable to keep the voltage drop to a minimum.

i have mine wired thru a 30amp circuit breaker and directly to the 2nd battery...

all my accessories, compressors, lights etc etc are fitted with anderson plugs so i can use them at the front or rear of the vehicle as needed...

Yes it must be possible as my standard plug at the rear is always live. Unfortunately it was done by the previous owner so I don't know how he did it:confused: I am guessing it is wired to the 2nd battery as are all the other plugs I have.

Sorry not much of an answer, but you know it can be done:)

Seems that, like most of the others here, I got around the problem by wiring a connection to my second (deep cycle) battery into the back with a fuse near the 2nd battery in the engine bay. Put a Hella plug into the back - no hassles with loose connection. Use the OEM plug to charge up the fluro lamp whilst driving to the next campsite.
