The electric soft top on the E36 convertible: the top module with its motors, position sensor, microswitches and the links to the ZKE. Hover or tap a row to see where the wire goes.

The convertible top module drives the top motor, the top flap (lid) motor and, on the automatic top, the windscreen cowl lock. It reads the top switch, the position sensors and microswitches, and asks the ZKE to drop the windows first.
It will not move the top with the car rolling (road speed on X13159 pin 13) or with a hardtop fitted (pin 5).
Redrawn from BMW ETM 5430.1 (05/99), E36 convertible; diesel and M3 parts are left out.
BMW labels every wire with its size and colour, for example 2.5 SW/GE: 2.5 mm², black (schwarz) with a yellow (gelb) stripe. Connectors are numbered X…, followed by the pin. The wires in these diagrams are drawn at relative thickness, so the 25 mm² battery cable stands out from a 0.35 mm² signal wire.
Codes used here: SW = black, RT = red, GN = green, BL = blue, GE = yellow, BR = brown, WS = white.
