There are three on most of the 535i's.

One up front which is only used on diagnostic.

The two used by the ECU are nearest the clutch ( if standard) or on the drivers side lower bellhousing.

Two connectors run up to the metal brace, then into the firewall.

Two are identical. Each is REQUIRED for running.
