Kenwood mic connectors?

So I?m looking for a new microphone for my TK840N. However I can?t seem to find information on what type of connector. The cheap after market one that came with the radio when I bought it used has an 8 pin Ethernet-like connector. The radio has a 6 pin phone-like connector. The cable is 8 to 6 pin. I assume that when a mic says 8 or 6 pin, it is referencing to the end that connects to the radio? Can anybody provide me a link to a compatible mic? Thanks.
