How to wire in a 12v power socket
Donkeys years ago I bought a 12v power socket (cigarette lighter thingy) from Jon Ison.
Would be really useful to have now but not 100% sure how to wire it in.
Do I want to go direct to the battery giving it it's own dedicated live and earth? Or shall just take the live from one of the Premier Loom
live connections?
Presumably it should have a fuse on the live... what value fuse?
Can't see any but is there any benefit to using the cigarette lighter socket from the donor Sierra instead?
Thanks! 
James

I did mine straight from the battery and I think I put a 15a fuse in it.

Can be either, historically fords had perm live cigaratte lighters, and GM had accessory fed ones.Tthe hire car we had in florida (Dodge/chrusler bus
thing) had 2, one from with bat logo one on accessory/key logo, giving you the choice to leaving something charging unatended (or connect a solar
panel to so it can charge the car?).
What do you plan to use it for? there is no right or wrong, just personal preference.

Trip to Southern France planned in it for July.
So thinking MP3, phone charger, satnav or maplight etc.

I took mine from a permanent live on the back of the fuse box and ran it through a 20amp fuse, basic wiring to the socket and earth via the nearest
available point.

I've got a relay thats switched by the ignition feeding mine. 20a fuse before the relay. Aldi have a socket adapter in at the moment with 3x cig
outlets and 2x 5v USB outlets.
I've currently got a 4x cig socket. When touring I often have Sat-nav, and phone plugged in, and occationally someone elses phone when they
haven't enough sockets. This weekend I'm swapping it for the Aldi one as my phone is now on a USB for charging, as is my camera and
I'll also have a video using 12v this year.

just be sure to turn things off if you do go down the permanant route, as leaving things on over night can lead to a flat battery!

3A or 5A fuse should be ample for low power electronics

I'd be putting it on a switched live, but thats just me.

Just to add, I put mine on a permanent live so I can simply plug a solar panel in over the winter to keep the battery happy.

Premier loom has accessories feed from permanent live, should be tied in with the side repeater feeds and coloured purple. The purple feeds from Fuse
7 are fused at 15 A
I'm addicted to brake fluid, but I can stop anytime.

They used to be all wired direct but a dreadful fatal incident in the UK about 20 years ago changed that, unattended very small child + locked car
+ cigar ligher = fire
However no problem with just using it as a permanently live socket fused at 5 or 10 amps (or 15 amps if you want to use a 12v impact socket),
just use adequate gauge wire, you can use a local earth to chassis.
If you take the + feed direct from the battery or master switch fuse should be close to battery end.

Thanks for the advice everyone!
Macbeast, nice one. Had forgotten about that on the PWS loom. Should make things easier!
Cheers,
James

mine is ign switched....(aux circuit) been tempted to make it permanent live but have not because i cannot think what i would leave plugged in while
the ignition is switched off. i have a 15A fuse on it which is a 175W device, enough to flatten a battery quite quickly.

I suppose an inverter to run something... errrr... maybe a laptop would be the only other thing I might plug in.
The top ones are about 300W aren't they?

I also used a relay switched by the ignition with the power side going straight from the battery. Max amps, no chance of over-discharging the battery.

Permanent live is useful for a lot of things such as acting as an input connection from a mains fload battery charger, or powering a 12v cool
box a permanent live is also very useful for those car to car battery boosters that plug in to cigar lighter sockets.
Aldi multi sockets are a bit iffy quality wise, the pound shops were selling the same type a few months back.

Quite probably.
The one I'm removing was fairly expensive, well known make as didn't like the idea of a cheap one. Last year I started blowing aux'
fuses in the Alps. Lots of head scratching and time up-side-down in the footwell and I traced it to a loose screw inside the plug shorting to earth.
The quality inside it was crap... and then when fixed the car wouldn't run 'cos I'd accidently pulled wires off the immobiliser, so
head first back under the dash. Any idea how tight a Fury footwell is?
As a result I'm happy using the Aldi one and having a look inside first.

I have used a aldi cig plug and dual USB socket in my truck at work for over 18 months and it has given no trouble, i often have both usb sockets
plugged into various bluetooths/ phones or satnavs most of every working day.

I had it apart this morning and it was a lot simpler inside and well made. As usual simpler is better; Virtually impossible for the live and earths to
contact each other, unlike my old one that only needed the plugs wiggling too often for it to happen.
Now fitted and working. Only job I got done though
