I bought a Kenwood cable off of Ebay, BUT it is missing a wire for pin 7, which is PTT ground for the Yaesu.
GET MAGNIFYING GLASS (to see wires in Modular Plug, RJ45)
COUNT the number of Wires, plus shield IF available.
BUT New Modular (RJ45); REMOVE the Connector on Kenwood Coiled Cord;
Insert wires (based on Yaesu FT991a radio functions - Read Manual); THEN CRIMP.
Search Engine (Google):

The Support Departments of Japanese Big 3 (Icom, Kenwood, Yaesu),
when their Replacement Coiled Cords are No Longer Available,
to “Just use widely available CB microphone replacement cords, and DIY install connector you need.”

The TRUTH is that the Radio manufacturers SOURCE these Coiled Cords and Microphones from Eastern Asian Suppliers (Japan, Taiwan, Korea, Malaysia, Indonesia, Vietnam, China, etc.)

BUY this one from ALIBABA (China) and Cutoff one end of cable for Solder wiring to microphone.
