This cable is specifically designed for the HD GP 2.2 (Part Nos. MC-586-2.2 and MC-584-2.2) only. One end has a 3.5mm female jack for your external microphone (not included). The other end has a 7-pin 712 (screw-in) connector to fit the “ECU-Mic” port on the base unit.
Sold individually.
Note 1: Works with HD GP 2.2 (Part Nos. MC-586-2.2 and MC-584-2.2) only. Not for use with any other device or any other brand
Note 2: This cable prevents the connection of the GP directly to an ECU or external power source. You can still connect the GP to your dash or logger (sold separately) and use the logger to power the camera and gather ECU data.
