Simplex 166-226 — 2 in (51 mm) ribbon harness for 4100 series LED and switch display cards.
The annunciator bays of a 4100 panel are built from stacked display modules, each tied to its neighbour by a short ribbon harness rather than by field wiring. Simplex publishes those harnesses as replacement service parts in three lengths, and the 166-226 is the shortest. Length is the only thing separating the three.

Order by length or order the wrong part. The 166-227 is the same harness at 6 in (152 mm) and the 166-271 runs 14.5 in. Different assemblies again are the 733-808 ribbon harness for modem modules and the 733-997 audio riser to transponder interface card ribbon.
