The instrument cluster (IP) connects to the car through a single 32-way connector, BD98 (blue socket, instrument-panel harness). Despite 32 cavities, only six are wired — the cluster is a CAN device, so almost everything it shows arrives over the Infotainment CAN; the rest of the connection is just power, ignition and ground, plus one hard-wired brake-fluid input.

• The cluster reads speed, gear, state-of-charge, drive mode and the warning-lamp requests off the
  • *Infotainment CAN** (pins 28/29). It cannot be driven directly by the head unit.
• The connector has a separate ignition line (pin 31) alongside the battery feed (pin 32) — the usual way a cluster tells “battery present” from “ignition on”. When powered on the bench the module is active on CAN (it transmits and answers diagnostics); the exact power-vs-ignition display behaviour has not been measured on this unit.
• A separate connector, BD93, carries a single USB line (to the head unit); it is not on BD98.
• There is no UART / serial console on the vehicle harness — a console needs the board in hand.
