Is that a thing to have two knock sensors wired in parallel?

v12 engine with some VAG parts but still not Bosch ECU.

Looks like one channel of pedal position sensor goes into the right ECU while other channel goes into the left ECU?

This vehicle uses pretty unusual Magnetti Marelli throttle bodies with CAN bus sticking out! Actually a Volvo part number see https://www.lamborghini-talk.com/threads/murcielago-pre-lp-throttle-bodies.230587/ see https://www.matthewsvolvosite.com/forums/viewtopic.php?t=78913

I see six wires and really confusing schematics I am not getting it :(

Pin 2 seems configures left/right position. Everything else seems clear

Yes, that's a legit explanation if Electronic Throttle Module (ETM) controls it's own DC motor on it's own. One thing which does not fit the picture is Volvo and Lamborghini both have six wires on the plug? The diagram at least does not mention that wire at all.
