This is the wire harness assembly for the UMS 7-35cc engine, the seven-cylinder 35cc four-stroke radial from UMS.
The part itself is the ignition wire harness assembly connecting the ignition module to the sensors and coils.
Why it is replaced: replaced when connectors corrode or wiring chafes through, which is the usual cause of an intermittent ignition fault. Supplied as a pack of 2, which is how these small parts are normally bought — you rarely need just one.
Fitting note: Support the harness so vibration cannot fatigue the conductors, and check each connector pin.
