JEDI speaker mic wiring-?

[Eaton90]

Hi everyone!
I want to know the pinout of a XTS/JEDI speaker mic (NMN6191B) connector and the purpose of all color wires in the speaker mic cord. There are eight of them:
Blue
Orange
Red
Yellow
Green
Black
Purple
Brown.
I'm especially interested in the ones wich run to the speaker and microphone head. If anuone has a printed scheme it would be great. Once I saw such a pic in the sheet which was in the genuine Moto programming cable box, but unfortunately I'v lost it
Hope someone can help me.

Here is the schematic diagram but you should note that there is electronics
in the connector on the radio end so it is not straight through wiring.

Thanks Fineshot1 for the diagram.

fineshot1,thank you! That seems to be exactly the thing I was looking for.

It's a little bit off-topic, but please let me ask here: I want to make a little cross-band repeater with my XTS portable. I'm going to connect it via mic cable with the audio outlet of a shortwawe radio. So what if I connect the red and blue wires (which originally let to mic head) directly to the audio-out and enable the VOX feature in my XTS - will it transmit automatically if the signal on the audio out is present?

You will, probably, have an impedance mismatch, and could also overdrive the mic input. So be ready to experiment with levels?

Hi All!
I have already tried that. It won't work because:
1. The output of the shortwave is unsequlched, so with the VOX feature on, Motorola will transmit constantly.
2. I took a wire off a simple remote speaker mic and it can't activate VOX like the special VOX-enabled accesories. What in the mic is responsible for enabling VOX?
I herd one can override it by turning the radio on with the PTT button pressed. But as soon as you press it once again the radio returns to the normal operation mode. The guy talked about GP300 and I haven't even tried it. Who knows wether it's true or not?
