Not sure if you're still looking for an answer to this or not... I was given this same make/model of microphone too. The 4-pin connector is confusing because it comes from a time when connectors weren't as standardized, so it has several names and lots of uses. It's sometimes known as an Amphenol, MC-M4, and/or CB connector. Manufacturers often used it for various applications, so the pin out was never standardized.
The DM-58 HL I was given came with a matching female 4-pin to male XLR cable. It was wired like this:
G + –
4-pin 1 2 3 4 (not used)
XLR 1 2 3
The good news: If you have $5, a few minutes, and some soldering know-how, you can make a cable to fit this mic.
