The 1986693-8: Side stacking allows multiple plugs to key together on the same wire entry plane.
Wire entry and mounting
Free-hanging in-line mounting with 180° plug wire entry — the wire axis aligns with the plug body, keeping the harness profile low. The insulation height is 0.459" (11.66mm). Termination is screwless leg spring, push-in: strip the wire, push into the entry, and the spring clamps the conductor. No tool needed for the wire, but the spring release slot accepts a standard screwdriver for extraction.
Confirm the mating half and wire gauge range before committing the line.
