Joe, you are correct. This is nothing but a screw terminal strip with wire wrap pins on the back side. I don't know exactly what it would have been used for except to perhaps fabricate a diode matrix or some other field assembly. I've never seen that KTU before. Most of the 2xx KTUs were used in 1A1, 1A2 and 6A systems.
