Today I fitted so 8p2 bi-Xenons to my a3 whilst I'm waiting to collect all the parts for my 8p3 conversion, I would need to wire for new Xenons anyways so thought i would do it now with 8p2 Xenons then led ones will be direct swap.
anyways after every thread I searched it someone always said get kufatec adapters to convert 10 to 14 pin and then run the bi-xenon shutter wires into the central electrics under drivers footwell. These cost around £50-£60 with delivery which I thought is kinda pricey for couple of plugs and little bits of wiring.
so I thought I will just do it myself without them. So I went on elsawin and checked out the wiring for headlights and realised when adapters are fitted the two cables that were not used for old headlight motors are no longer required. So me thinking these can be controlled from headlight switch I checked elsa and found that they are wired straight back to headlight from the switch. These are doubled up at the switch so just split them.
removed from pin 3 of the 7 pin connector
so there's no need to run new cables in for xenon shutters I'll just use one off each headlight for this. So I bought two 14 pin headlight adapters and two repair wires from Audi which was £18
Re-pinned the new plug as per wiring and extended the cables that ran to headlight switch to run to correct positions on the central electrics and covered with loom tape so looks OEM
Now when looking under the Bonnet headlights looked wired OEM as possible with no adapters used and no extra wires can be seen as I used switch feeds to old headlight motors.
Juat thought I would let others no if they wasn't keen on running new wires in and having to take scuttle panel off ect.
