TR6 '73 TR6 Left Hand Door Switch

From what I understand of the electrical schematics for this circuit, there are 4 connections:

1. Purple/Orange between the switch and the buzzer
2. Purple between the switch and the ignition switch
3. Purple/White between the switch and the transmission tunnel lamp circuitry.
4. Switch to Ground.

However, it looks like all of the LH door switches available only have 3 connections available.

How does this work?
 
Hi Daniel,
According to the wiring diagram in my Bentley manual and my '74, there are 2 LH door switches.
 
The 73 has the tunnel light??
the purple doesn't go to the switch. Just to the light according to Dan's colored ski-matic
