Object is a cluster of 15 individual wires tied and taped together into a cable. At one end the individual wires terminate in small banana jacks numbered 1 to 15. At the other end is a rectangular plug with 3 rows of pins: two offset rows of 8 on the outside and 4 larger pins in the center in a keyed (asymmetrical) arrangement. There is one separate wire, probably a ground, that is not terminated. The wires are printed with "Amphenol" and some numbers.
