Ah, I wondered about that - the missing black wire seems to attach to a lug and the lug just gets attached via a screw to the frame. To just get the bulb to light, are there 2 wires that could get attached to base and 16V? The semaphore action seems to work, so that's a start, I loosed the screws, it won't open fully but the linkages seem good - man, I only seem to buy junk! Does the 23761 hook up differently? I didn't get a red/green control button, should I have?
