12v Sockets
Hi all,

I've done the easy rear 12v socket mod to my 2008 110. Now I want to put a couple of extra ones in on the passenger side of the dash for satnav etc etc so I'm not trailing cables down to the one infront of the gearstick.

Is there any 'easy' way of connecting these up behind the dash? I was thinking putting piggyback connectors onto the back of the existing 12v socket and then running a couple of wires to one socket, then off that in parallel to the other one which is just a USB socket? I won't be using them for high ampage stuff, just satnav, dash-cam, phone charger etc so is this a sensible option or no?

Cheers! Thumbs Up Pete

I did exactly that but rewired via aux fuse box because I wanted continuous feed not ignition on

I always try to solder and heat shrink wrap

Here's what I did this afternoon:

I wanted a 12v USB socket in the passenger side glove box for powering my TomTom and dashcam etc, and also an extra 12v socket on the lower shelf just as a spare for the odd occasion a phone charger may be required etc. Keeps things tidier and won't have wires trailing over the dash in front of the gear levers.

First of all, I removed the stereo then pulled the dash facia off in the usual manner (two screw and pull the whole thing towards you).

I then checked there was nothing behind the plastic trim where I wanted to locate the socket, and then used a step drill to drill a 30mm hole. The USB socket can then be fixed in place using the nut behind it, although it might be handy to attach your connectors and thread some wire down behind the dash as it's a little fiddly to get your hand in there.

I am using black and red 5A wire here with crimp connectors. I don't think the wire to the standard socket is much more than that? However, I don't think this is the best solution, but simply what I had available. I might redo it if I find myself using them for things with a greater power demand, and use solder connections for better reliability.

Question: Is the standard 12v socket on the dash fused?

The second socket, same as the first step again, check, step drill etc.

I then connected the upper USB socket to it in parallel using piggy-back connectors. A little 'bodgy' I know, but it works and I made sure they were attached firmly so they won't come off easy.

To connect to the original socket again in parallel, I had to remove the original loom connector. I know you can just remove the wire connections out of the plastic shrouding by pulling the tab with a screw driver, but after faffing about for 10 mins trying I just cut it off. Laughing

...and put on insulated crimp ones.

I then connected the new sockets to it using more piggy-backs.

All checked and very useful Smile

Any suggestions on how I could improve this or whether you wouldn't recommend it etc would be welcome. Just using my basic knowledge of electrics here Laughing

I always use the heat shrink connectors instead of the crimp ones Thumbs Up

^^^Agree
Probably best to replace the bare crimp connectors (Pic #7) with shrouded ones for the 12v side of things.
Potentially saves changing fuses at a later date! Thumbs Up

Tidy job though, well done.

The un-insulated ones are the 'piggy-back' connectors though. Can you get insulated ones?



EDIT: Turns out you can, just bought a pack of 50 and will change them over Thumbs Up Pete
