What connector is shown in this diagram?

Connector C2145a, a gray (GY) 22-pin female connector for the Lighting Control Module (reference 14401), with pins 1–11 on the top row and 12–22 on the bottom row.

Which pin carries the Vehicle Speed Sensor signal at the lighting control module?

Pin 5, circuit 679 with a gray/black (GY/BK) wire, is the Vehicle Speed Sensor (VSS) + input.

Which pins on C2145a are not used?

Pins 1, 2, 8, 15, 19, 20, and 21 are listed as not used.

What does the asterisk (*) on circuit 296 mean?

The asterisk denotes the Police variant. On pin 7, Police vehicles use circuit 296 (WH/VT), 'Voltage in Run or Accessory (overload protected)', instead of/alongside circuit 218 (WH/VT) autolamp sensor control.

Which pin controls the rear window defrost relay?

Pin 12, circuit 688 with a gray/light blue (GY/LB) wire, is the rear window defrost relay control; pin 18, circuit 1010 (DB/OG), is the defrost switch input.
