12V plug in luggage compartment

Hi. Looking at doing this modification and adding the second boot light.

Has anyone managed to get a step by step guide or is able to describe the process to me. Mainly the electrical wiring.

Thanks
 
By wiring the 12V boot socket in parallel with the 12V socket by the hand brake, you're using a circuit that's already appropriately fused. However, you must use wire of the same gauge, otherwise you're introducing a fire risk.

Similarly, the second boot light can be run in parallel with the existing boot light. However, the current for this light is supplied by the CCCU, not from the fuse board, so you mustn't use a bulb that's any more powerful than the original one on the left-hand-side.

Cheers,

Tom

Thanks for the quick reply. As I don't have any soldering equipment, if I used terminal blocks to join wires, would the wire I add still need to be of the same gauge.

Are you saying that I don't need to add a new fuse for the second boot light either? Providing that I find one that matched the original
 
Personally, I wouldn't use terminal blocks to join wires that will be carrying significant current unless the terminal (and your joints!) have higher current-carrying capability than the wire itself, simply because it may otherwise introduce a point of electrical resistance. Resistance results in power dissipation by means of heat. You don't want that!

A fuse for the second boot light isn't strictly necessary, but adding one cannot do any harm. I always use light units that match the original, because I'm an OEM purist and love a bit of perfect symmetry. :)

My aim would be to find an original light anyway. Probably my minor OCD

How could I join the wires without terminal blocks or soldering?
 
Ok guys just fitted a 12V Aux Socket, so here's an image showing where I positioned it...
All dimensions are in mm. Hope this helps.

jellybean it would've been great if you could've posted photos of the cabling and parts used for this mod :)

i also need to tackle this upgrade at some point but more info for the dummies like me would love this ;)

5 years on and still not started lol

Apologies, I never thought to measure cable lengths! When I can unload the car I will take a stab at cable lengths, and see if I can fish the connections out and photograph them.
I fitted a pair of LED light units, so cable size was what I had available, rather than critical! The light units came with twin sockets, with plug in flylead in one. I cut the plug off the flylead and joined the cables with crimp connectors. At the standard nearside position the standard A2 light plug was fitted. I then used scotchlock connectors to join my cables into the loom. With LED's Its important to get the cables the correct way round.

Did mine today! And second boot lightView attachment 65752

Looking great Simon.

Still not fitted mine yet but will get it done when the weather improves here as it’ll be a small part of what I’m doing whilst the panels are off. Did you go direct to the battery or run it parallel to the standard 12v socket.

The pop out sockets do look nice.

Kind regards,

Tom

Regarding wiring, not finalised that yet. The battery route looks a bit simpler and will save getting carpets up to the centre console.
 
You will probably break some of the trim retaining clips when removing the trim panels around the rear lights. Well I did anyway.
I posted a want in the market section but after a bit of research a complete set of panel fixings is still available from Audi.
The boys @ Crewe Audi came to the rescue and sent me a set very quickly indeed. Thanks lads!
The part number is 8Z0898447. for one side only though
Job for next week putting it all back together again after lots of cleaning and general tidying up. Pics to follow.
 
be sure to take some photos Simon because i would love to finalise this mod at some point soon! i just need to sort out my sunroof issue....fix one problem and create another with me ;)
