My whole intention is to rewire a second remote mic jack on a TK-6110 to be used with a Motorola Mic. I am using a Motorola HMN1056C Mic. the pinout is confusing from looking at the schematic for the mic jack on a GM300. I only need 4 wires (Hook, Ground, Mic Audio and PTT) they are only using pins 3,4,5 and 6 on the mic connector, but I am having difficult IDing which pins are which function.
