I never actually found a switched 75X terminal connection, but I stopped looking once I figured out an alternative solution. I did read about a switched black wire under the steering column that people tap into for other stuff. If you find it or something else let me know! My work around was this:2. I also looking for that 75X terminal, have you found it ?

T17d/16 - Run a new wire to switched power (I used the gasoline fuel pump relay power pin Relay Position #1 in interior carrier. The gas fuel pump relay is not needed as the diesel one is in the engine harness/plenum chamber carrier. The power supply pin is the big one on the left, I broke the relay, 167 printed on it, and salvaged the pin to make a crimp-on blade connector)
As for the BBK, I'm just following what others on Audizine have done! Basically you obtain some Touareg calipers (same as a Cayenne or Q5, but cheaper because they aren't painted and don't have the Porsche/Audi tax). They can be 4 piston 1LE or BM5, 6-piston 17Z or 6-piston 18Z; the 4-piston and the 17Z take 330mm rotors while the 18Z takes 345mm rotors.1. Please explain as much as possible about that BB upgrade !
V70R
Are we talking Volvo or what ?
.
A common 330mm rotor choice is V70R rotors for, you guessed it, a Volvo! Using them does required modification to both the calipers and the rotors. I think about 1/16" has to be taken off of the inside surface of the mounting ears to centre the caliper over the rotor. The rotor also has to be modified by drilling each lug bolt hole out to 3/4" / 19mm so that the Volvo 5x109 pattern will fit the Audi 5x112 (that part is super quick). I think others have used C230 rotors or some other Merc rotor, those require the centre hole to be opened up 1-2mm to match the Audi hub diameter, but then your lug bolts will work fine as they are also 5x112 from the factory.
After that you just need B7 RS4 stainless brake lines and a hardware kit that you either DIY or purchase from Eurobraking or JHM!
Even though I bought them months ago, I only just got my calipers machined last week before I went and blasted them with crushed glass to prep for powder coat. Now I've gotta find a place for that and do some price shopping. Finding a machine shop that could do it took me forever, and they ended up ripping me a new one and charged me $240 for what was likely 30 minutes of work. AND they lost one of the nuts for my mounting kit
This thread is a pretty good read and it's where I got 99% of the info above: clicky
Here's a pick of before and after crushed glass blasting, it's so fun!
