it a box that when triggered either added or retarded a certain amt of timing (likely for emissions purposes). iirc it retarded. You do not need nor want it. Keep it tho as a restoration guy somewhere down the line may want it. install your dist & dial in the subsystems in order: initial/total/springs/vac adv (if used & I would). just run the black wire to the coil neg pri terminal and cut the (2) wires out you mentioned or tape em off whichever works for you
