ICOM IC-HM10 wiring diagram/color coding/picture help

I'll try to keep this short and easy to read.

I'm just getting into HF. I picked up an Icom IC-730 rig, it came with an ICOM IC-HM10 microphone. But it didn't have the 8pin connector on it.

I'm trying to find an easy to follow pin1=red, pin2=purple, type schematic or something. It can be more complicated than that, but not much. I have a multimeter, I've traced some contacts, but I'm still not 100% on what goes where. Closest I've found is http://homepage.ntlworld.com/rg4wpw/hm10.html

I've at least got what is ground/+9 volt etc with that. I can trace a handful of wire back, but even then they combine or hide behind a PCB, i'd rather not risk breaking stuff.

TL;DR: take me a (color preferably) picture of your IC-HM10 mic wired to your 8pin connector please! Or if you can just remember what colors you wired to what pin off the top of your head that'd work too!
