Removed Torx (T20) screws around perimiter of inside cover. Lifted cover and inverted it, then disconnected the two terminals from the wax motor. Wire and motor terminals had green corrosion and entire motor/latch assembly was caked with accumulated detergent. After ensuring circuit was not hot, cleaned wire terminals by soaking ends (one a a time) in white vinegar, then water, then a spritz of WD-40. Removed old assmebly and reservoir, then thoroughly cleaned inside cover and vacuumed inside of dishwasher door. Took digital pics at each step of disassembly as a reference when reassembling.

Instructions provided with conversion kit are useless. Attached parts, motor, and gasket to new assembly first, using old assembly as a guide. then attached to cover before replacing reservoir. Inserted plunger into reservoir and twisted to secure. Installed o-ring and mounted reservoir; slot on reservoir mates with tab on assembly, and white lever arm actuates plunger. Reattached wires to motor and replaced inside cover. Ran a wash cycle and confirmed cup lid opened.

Note that my model only had one wax motor, so new assembly was identical to old and the Y-cable was not needed. As another commenter pointed out, latch assembly will not appear to work correctly manipulated by hand until you remember that cup lid holds latch at midpoint of travel at start of wash.
