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.

View looking into the harness plug's mating face. Bottom row = pins 1–16, top row = pins 17–32 (left → right).

• 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.
• Power (pin 32) keeps the processor and CAN alive; the display is gated on IGN (pin 31) — so

with power but no ignition, the module stays awake on the bus but the screen is dark.

• 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.
