So I have a couple of these military version Rb's. They are very similar to the civilian FRK-S which I also have one of. They have a Winchester connector on the top of them for all the 20 pins that carry the signals and power. I figured I'd look for the matching connectors to make some cables. Up to this point I've been using my own wires with female aviation crimp connectors for each pin. I found a place that had 6 of the civilian connectors the SRE ones. I asked for a quote for two of them. I was shocked to find out the connectors are $334.75 each so $669.60 for the two connectors that mate to my M-100's. I think unless anyone knows of any other sources for either of these that I may skip this route.
This is what it looks like.
