I have an Amphenol type, 91-MC3M, 3-pin screw-on connector that i need to connect to an XLR or a 1/4" male guitar cable. Need steps on where the copper wires go and how.
I think that's what he wants to do.
I'd say, unless someone else knows for sure, desolder the xlr connector on a mic cable and connect the amphenol pin for pin.

When you said "you wanted to connect it to an XLR OR 1/4" male", I am assuming you are talking "balanced" which would be a 1/4" TRS. T (on the TRS) would go to pin #2 on the Amphenol/XLR connector. R (on the TRS) goes to pin #3, and the S (sleeve) which is the ground/drain/braided wire goes to pin #1
If you are going "un balanced" you use a 1/4" TS plug and lift (do not connect the wire) that comes from pin #3
You may have a bad connection at the Amphenol end, or a bad cable. You need to check the continuity of each wire in the cable. Do you have a meter of some kind (volt/ohm meter) or some type of continuity tester?
Even without this, the first thing you could do is resolder the Amphneol connections, or even better, cut a few inches of the cable off and remake the connections. Cables tend to break at the entrance to the connector where the most bending and stress is placed on them.
