AI says:
Top connector (in the recess, 2 wires)
Wires: typically 2 (often red/white or similar pair)
Function: Airbag igniter (squib)
Why: airbags nearly always use a dedicated 2-wire plug for the firing circuit, often positioned centrally or slightly offset.

This is the critical safety connector.
2. Left connector (larger multi-pin with many coloured wires)
Wires: multiple (green, yellow, red, etc.)
Function: Steering wheel controls
Volume / track buttons
Phone / voice controls
Possibly cruise control (depending on model)

This carries low-current signal wiring back through the clock spring.
3. Right connector (smaller multi-pin, fewer wires)
Wires: fewer than the left plug
Function: usually a combination of:
Horn switch
Illumination / backlight
Sometimes secondary control signals

Think of this as auxiliary functions.
How it all ties together
All three connect into the clock spring (spiral cable unit) behind the wheel, which:
Maintains electrical contact while turning
Links everything to the vehicle’s wiring loom
