The 8HP BMW shifter are directly supported using the MaxxECU 8HP (GEN1) cable harness (BMW 8HP shifter), product ID 2287.
Using the 8HP shifter emulation feature, any supported keypad can be used instead of a real shifter.

4 - Paddle shifters.
Paddle shifters from example Mercedes, part number A 171 267 00 46. Or any other paddle shifters (or buttons on the steering wheel) that "closes" the circuit when pressed and wired directly to the MaxxECU.
Note: Paddle inputs are required for the 8HP transbrake feature.
Example on how to trigger the digital input for paddle up in MaxxECU wired to DIN1, could be captured on AIN or even CAN.
