Any issues with figuring out which wire splices to which?

Scott, I used the splice-in kind of Bosch O2 sensor replacement to
replace an upper one on my wife's biturbo A6 and it has been fine. The
sensor was exactly the same as the original except you reuse the stock
connector. The upper O2 sensor wasn't too hard to change with an O2
socket and a long extension. I had to get creative to get some PB
Blaster down there to help break it loose. I used three straws pushed
into each other and that was long enough to trickle the PB Blaster
down to the O2 sensor threads and soak them real well.
