Adding Accessory Socket

Hi everyone, I'm after some advise on wiring in an additional accessory socket.

I have purchased a dual 3.1A 12v USB socket and car cigarette lighter and want it to come on with the ignition (NOT permanently powered).
I can see I have several spare fuse locations on the Instrument Panel Fuse board under the glove compartment and want to use a 15A fuse similar to the factory fitted 12v sockets. How do I know whether the spare fuse locations are on permanently on or ignition powered and how do I wire in the socket to the fuse? Do I need a relay also?

Any help/photos would be greatly appreciated.

Hi Corona, what location are you putting the socket? As dependent on that will depend on the best place to get a feed from, you don’t always need to go back to the fuse box.

Hi Kevin,

Thank you for the quick response! I'm installing it in the top glove box on the left hand end so being so close to the fuse box thought it would make sense to do it right.

Ok, makes sense then, I’d probably tie into f47 then, that’s the fuse for the 2nd row power socket (rear of the centre console) its fused for accessories and only on with ignition.

I’d just get a piggyback like this and chop the accessory off to wire yours to the adaptor.

I hadn't thought of doing that, thank you.

We only ever use the 2nd row accessory socket for the kids phones/tablets so no big draw from there. I want to hide the large Garmin satnav cigarette plug in the glove box and at the same time have a spare USB plug without having to have wires permanently into the standard console sockets so this should work perfectly, thank you Very Happy

If part of its for your Garmin the worth hardwiring that direct on its own, via a hardwire kit, leaves you either the Spare socket or means you can install a single instead

As above! Thumbs Up If you do run a hardwire kit then my top tip is to place everything in the glovebox and run the cable from there up rather than connecting to the camera and running down, as the small usb type connector will fit through a pre cut hole in the glovebox surround, and can be run up the side under the rubber door trim (just pulls off) along the side of the airbag and then tucked under the headliner. Adjust the length as required once the cable is run and then keep the spare cable behind the glovebox.

Also be careful not to run the cable round the rubber trim! (Ask me how I know about this!) Laughing

Should be about a half hour job to get a tidy finish.

Thank you for the suggestion Kevin, I'll have a look at that option also. My only concern would be that the Garmin satnav seems very fickle in which extra cables it likes. I've had 5 different extension cables sat between the official Garmin 12v plug and the satnav (due to location of the satnav) and each one causes the satnav to tell me "the attached charging cable does not work". When I remove the 'extension' section and only use the official cable it works fine.

After doing searches on this forum and other areas of the internet it seems a common problem with some Garmin satnavs.

Plus 1 ref hardwire kits etc

Also as an option for other ideas I fitted a fuse box in the upper glove box, wired it to my Aux battery via a relay so only comes on when the ign is switched on

Therefore providing me with 6 x fused 12 Vdc feeds for various items, ie, for the lower panel , hardwire wire supply for a dashcam, charging points etc , plus as mines a base model fitted a 3.5mm Aux socket in one of the blanks of the heater module

Lower panel consists of , volt meter , inside cabin temperature, usb charge points

Hope that also helps with different ideas

A hardwire kit will remove the need for extensions... they are available in different lengths...

Thought I would give an update on what I ended up doing, albeit temporary until I tidy up the cables.

I fitted the Garmin satnav in the centre console and fed the cable through a hole under the rubber mat, (this hides the hole if/when I upgrade to a new vehicle). I then fed the satnav cable down through the centre console and behind the lower glove box. I did the same with the Garmin dash cam cable via the A pillar to the same area behind the glove box next to the fuse board.

I purchased the piggy back fuse carrier as recommended by KevinD3 and piggy backed with F47, cheers Kevin Thumbs Up .

I then sat the accessory socket behind the upper glove box and fed the cables up there, using one of the retaining screws for an earth. The cables need tidying up but once the left vent panel is replaced it is out of site.

This way nothing is permanently fitted and I can remove/alter as required in the future, and still have all the factory fitted accessory sockets available.
The Garmin satnav screen/UI is far better the the original LR satnav, and I added a shade which not only stops sun glare but also hides the Garmin logo. Being removeable I can put away if parking in an unsecure area but also take inside easily for updates.

Not perfect but gets the job done Whistle
