Wiring for 12vdc socket in load area

[brucekeeble]

Hi guys..

So I've looked through what threads I could find on installing a 12vdc socket in the load area.

I have a 2008 (facelift) Berlingo Multispace VTR.

There is no socket installed from factory but I have one on order and will place it where the factory location is just next to the drivers side rear speaker.
I've had the panel off today and there is a bunch of wiring behind there.

There isn't a specific pair of wires that look like they would connect straight to a socket.

Does anybody know which of the cables I need to use? It looks like there is some form of relay in there also.
Or do I need to run a new supply from the fuse box?

Any help would be much appreciated and if I've missed a thread explaining this already then apologies.
I'd rather not start disconnecting wiring to the rear lighting cluster without knowing what's what.


Thanks in advance.

the wiring with connector should be there, can you post some pics with all the wires ?

here is some info about wiring and connector:

I had a 2013 Peugeot Partner which also did not have a rear 12v Socket. Like you, I took the driver's side rear panel off only to find there was no plug ready for adding a 12v socket. I'll try to find the wiring diagram and will update this post if I find it.

Update: Diagram attached, probably not much use I'm afraid.

That you both.. I'll rip the panel off tomorrow and snap what's in there. Theres definitely no cables with plugs attached. There are two grey wires that aren't attached to anything but Im pretty sure that's not them as they come from the relay type box.

Anyway I'll get some snaps and update tomorrow..

Thanks again.. Appreciated..!!

So this is whats behind the panel on the drivers side..
Not sure if that relay type box is original or not. 

Definitely no spares with plugs on..

Any thoughts?

Cheers

I think someone modified the electrics there, the wiring looks altered and messy

The item in your hand looks like it's for a towbar ? Either that or a split charger for a leisure battery.

Other than that, from memory, it looks like mine did.

Im suspecting that it has something to do with the towbar that has been fitted. Might be a light relay or something but there is a permanent 12vdc live been added from the battery under the car to the rear..

The only other way I guess would be to run a supply from the rear of the dash 12vdc socket to the boot as I think the same fuse would have supplied both anyway.

Its not the end of the world but we sometimes use a cool box and a small portable pressure washer as I use the car for moving bikes around mostly.

Annoying as the socket arrived today so was all set.. Ah well..

Thanks anyway

Yeah I suspect its for the towbar.. I wouldn't know which cables are from the correct fuse that's the problem without spending ages testing them all.. not keen on disconnecting any of that to be honest.

If you can see the part number of the towbar relay, it should be fairly easy to find the wiring diagram for it. It will have a +12v supply, but it will probably be switched on with the ignition rather than permanent live. It should also have an inline fuse to prevent overloading. But if there's no fuse, you can always add one.

Just noticed that my post is a bit out of step and that you'd already noticed the +12v feed for the relay. As above, you can use that and add a fuse if needed. Must say I'm a bit surprised that the live feed runs under the car though. Maybe that's standard practice these days & I'm simply out of date.
