Adding a power socket in the boot

[verytalldave]

I have a facelift 2004 W203 and it would be handy to have an extra power socket in the boot for the new fridge box I have just purchased. I could run a lead through from the outlet in the dash, but its a bit naff. I would rather a proper socket in the boot.
Has anyone added one and if so, is it easy? Is there a convenient point to take the power?
I await anyones replies.
Many thanks in anticipation.

what type of power socket are you talking about? I assume you are talking about the power accessory socket (Cigar lighter type)? Quite easy really, but it depends on how deep you want to dig to connect the new socket to either a permanent live (On constantly) or a switched live (On when you turn the ignition key)? you can purchase the socket and wire from most car accessory shops. Until you have decided on how it's to be connected, switched or permanent, I can't really advise you correctly?

I suppose its got to be permanent live really. You cant go switching a fridge on and off or else it defeats the object.
I would simply unplug the unit when not required.
As you say, it would be a cigar lighter type.
Thanks for your reply.

i have fitted the W210 power socket in the boot of my 124 estate - looks OEM and works perfectly. Very cheap mod at around £6 for the parts from MB.

I'd suggest to connect to an "under-key" feed, like the factory 12v plug in the cabin

Part numbers?

I had a socket fitted in the boot compartment. I believe the power come from the connection block where the rear SAM module is located (left side), where you can take a 'always on' 12v feed. I chose to have the socket (fused) put in the black removable plastic bits under the parcel shelf. Dunno if this is of any help? Shame with this weather you hardly need a fridge!

Are all the parts necessary in your experience of fitting it?

see my post at the bottom of the thread with the part numbers.

only the main block and spade connectors are really needed from merc. you can then get the wiring or the spade connectors from halfords or the like cheap:

A0075458426 : PIN BUSHING : EUR .78 (X2)
A2108200951 : FITTING MOLD : EUR 9.07

+ about 5 metres of wiring to get to the battery at the front should do + a inline fuse aswell

Another mod to add to my list. Does it have to be installed in the boot or could it be installed in say the centre armrest?

I'd say where do you prefer, it's only a matter of finding the proper space and to pass cable (dismounting the involved parts)

I would have it in the boot, but I dont think the upholstery back there will be a good enough support for the point. I reckon either in the centre armrest where it would be supported was a better bet, or maybe even attached, sticking out of the back of the armrest for rear passengers. Hmmm decisions decisions

 

[1998K]

Why don't you add both? One in the boot one in the armrest!

 

[SilverSaloon]

i put mine here:

...pointing downwards. The back of this carpeted trim is hard plastic so supports it well. Just drill a pilot hole, then a slightly bigger hole, then use a file to fine tune your hole so the lighter socket fits nice and tight into it.

I've used mine for the kid's rear dvd players so far. I also use the same wire i added to run to power my caravan fridge on my towbar electrics.
