I have a 6 wire D104 . How do I wire it to a Ranger 2985 dx ?

Wiring a 6-wire D104 microphone to a Ranger 2985 DX requires connecting the wires in the correct order and configuration.
The Ranger 2985 DX has an 8-pin modular plug, and the D104 microphone has a 6-pin modular plug.

2. Connect the black wire from the D104 to the 8-pin modular plug's pin 5 (Ground).
3. Connect the white wire from the D104 to the 8-pin modular plug's pin 6 (MIC + Audio).
