Batboard

Thanks for reading this, can someone please tell me the details for the GM360 accessory connector on the rear of the set. I cannot find it.

Also when linking two of these radios together whats the best way ? are all functions on the rear accessory connector ? so just two radios linked up this way or is it best to take audio from the front mic port ?
Andy help please.
