====== Instrument cluster — connector pinout (BD98) ======

The instrument cluster ([[hardware:ip|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.

(left → right).

===== Notes =====

  * 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.
