One thing I find lacking with the Fiesta is not having a 12v socket in the boot for running accessories or a cool box when going out for the day - so I decided to fit one.

Here’s how I did it.

Firstly the parcel shelf support trim needs to be removed. This is best done with the rear seat reclined:

Now for the wiring.
For my requirements I need around 7A. That is too much to load onto any existing circuit around the rear of the car, so I decided to run a new feed from the fuse box.
I ordered 5m of thinwall 11A cable. When it arrived I was surprised at how thin it was!
After some reassurance from the supplier that it will be fine (fingers crossed), I also ordered a fuse adaptor, a 10A fuse and various crimp terminals.

I then set about installing it all.

To access the fuse box behind the glovebox, first empty the glovebox and squeeze the sides together so that the glovebox can open fully exposing the fuse panel behind.

Nice guide, love the comic book style!

Excellent job.
How did you do the comic book layout? I like.

Nice guide mate,
[s]but sorry to say had you removed the panel on the right side of the boot instead of the left their should be an orange or in some cases a black plug for the rear of a 12v socket already their and fused, just need an earth feed.
but end results are the same quality job though[/s]


i initally assumed that ford had fitted a 12v supply to the right hand side of the boot in the mk7 fiesta,

because they have done it in the mk6 fiesta and all mk2, mk2.5 also the new mk3 focus
nut i have later found my assumption to be untrue thus i have edited this post because it was misleading

Thanks guys.
Lenny, before I started I checked the wiring diagrams and could find no evidence of provision for a boot 12v socket.
I also physically checked both sides and found no spare connectors.
Do you have any other info?

ok mate,
its unusual that ford havent put one on the right hand side of the mk7
they have gotten one fitted to the mk6 and also the focus including the new mk3,
but i have since checked ford microcat for the mk7 fiesta and to my surprise their is
[u]N[u]o loom pre fitted to the car for the [/u]12v socket[/u].

Thanks for the confirmation.

i have since edited my inital post on this topic to prevent any misleading information to others following your great guide.

Good to see such a useful accessory item in a well laid out fitting guide.
I also think the comic book style presentation is spot on.
Thanks Steve.

Thinking of doing this type of mod. Is my only real option to get some juice from the fuse box same way as tunnelrat has done it? I have no probs with this (well other than not feeling overly confident sticking wires to fuse box). but I would do It to get the mod done. Though I would also put 10 amp fuse somewhere to ensure the safety aspect.

By the way, is it some sort of special connector that has been used to tap into the power of fuse box? Its hard to make out from the photo.

The connector is this: [url="http://www.ebay.co.uk/itm/Add-A-Circuit-Fuse-Tap-Piggy-Back-MINI-Blade-Fuse-Holder-ATM-APM-12v-24v-12-volt-/180735820543?pt=UK_In_Car_Technology&hash=item2a14b1c2ff"]http://www.ebay.co.uk/itm/Add-A-Circuit-Fuse-Tap-Piggy-Back-MINI-Blade-Fuse-Holder-ATM-APM-12v-24v-12-volt-/180735820543?pt=UK_In_Car_Technology&hash=item2a14b1c2ff[/url]

Thank you for the link. This makes it much easier. I have ordered one now. You gotta love autostar, one of my favorite sellers.

Cheers

What a great guide, going to be doing this modification next week when the parts arrive.

Sorry if I missed it, but can you tell me if this new socket is live all the time or does it only switch on with the ignition, unlike the socket below dashboard? I really need it to switch off when car is not running.

Thanks in advance for you help.

If you want it ignition switched, simply locate an ignition switched circuit on the fuse panel using a test meter.
Mine is permanently live, but is also now fitted with an electronic power saver, so that I can run my cool box in the summer knowing that as soon as my car battery dips below 11.5v, my cool box will automatically be disconnected thus saving my battery.

Ok - done the modification and found that the fuse position on the bottom right corner (parking sensor) does the job in that it comes on only when ingition is on position 2.

Many thanks for your help.

Just installed a 12v socket in my boot after reading this guide.  Thanks by the way.

 

This power saver seems a interesting device, could you give me some more information about it.

I have a device similar to this hard-wired: http://www.force4.co.uk/732/Waeco-Battery-Saver.html
