Hello again Sailesh.
Whilst this is an awesome idea I’m realising it’s not quite as straight forward as first suggested. The rear light switch pack that the A2 left the factory with doesn’t sit flush with the remainder of the headlining; it sit proud of it. As shown below it is located on a bulge on the headlining:
The A6 C5 rear light switch pack as doesn’t sit flush with the headlining, it sit proud on a bulge. I think that the A6 C5 rear light switch pack will not only need to come with the headlining metal surround, it’ll also need to come with a suitable cut out from the headlining biscuit which accommodates the corresponding bulge from the C5 to house the switch pack:
Hopefully you can make out the bulge where the switch pack is mounted
It’s this bulge in the headlining which allows space for the top side of the switch pack and its connectors between the roof.
This shouldn’t put you off though Sailesh as it’s a cracking idea and one that I may borrow when I reupholster the headlining in a certain JR A2. In addition to the rear light switch pack you’ll need a donor C5 headlining to take the bulge from which can then be transplanted/adhered into your A2s headlining biscuit; as such it’s a full reupholstery is required for sure.
Still a great idea and one I’m convinced I’m going to do myself as I’ve often wondered if something like this could be done, I’ve also thought of adjusting the front of the headlining to house a larger front switch pack that has the sunglasses holder within it. This will of course only work for non-OSS variants though. A phase of testing the ultrasonic sensors before any headlining biscuit modifications must take place of course.
To save on the minimal additional load to the existing A2 circuits, I’d be using LEDs which will be just fine. Probably a good safety measure would be to add a Dynmo label above the bulbs saying LED Only so that any future owner has been warned to not fit less efficient incandescent bulb.
Still a great idea and one I’m considering when I get round to this task, which is getting quite desperate now as the headlining fabric is close to touching the boys heads in the rear of the car.
Before we proceed there is the requirement to understand the differences in the connectors between the 2 rear light switch packs. For the sake of experimentation, I have just purchased one of these rear light switch packs (4B0947111) in black for £12 delivered to see what’s possible:
Kind regards,
