Cables for a Motorola XTS1500 HT

Hello, i am building an interconnect link from computer to a Motorola XTS1500 handheld for a mobile rig. I know there is a snap on connector for microphone port to audio cable. I cannot find the part number or cabling to make this work. Any help would be greatly appreciated.
Thanks,
Brian Holub

Brian,
I’m not finding the pinout info, but there is a programming cable offered by KJ6ZWL on eBay. Maybe he has full pinout and nice enough to share it. You can lookup email on QRZ.

When nothing else works, I buy the cheapest speaker/mic for the target transceiver, reverse engineer the pinout and salvage its cord for the cable build.
