You are lucky .. I have this hand microphone (Yaesu MH-1B8) on the workbench right now ! (wiring a new coiled cord cable).
BTW, Yaesu Parts NO LONGER has the OEM replacement cable (correct wire color, conductors) for this specific Yaesu model of microphone.
Yaesu MH-1B8 Schematic / Wiring Manual (PDF attached)
1 - GREEN
2 - YELLOW
3 - BLUE
4 - BROWN
5 - ORANGE
6 - RED
7 - BLACK / SHIELD around WHITE
8 - WHITE
HINT, IF you ever have to use a 7 conductor + shield as replacement for original Yaesu cable (8 conductor plus shield) -
wire the shield conductor to "7" on Foster circular connector and wire to both points inside MH-1B microphone.
