Rad's 'RadRover 6 Plus and RadCity 5 Plus Wiring Harness Replacement Guide' documents this loom and its colour-coded connectors: 'wiring harness main: black with 11 pins', 'motor: black with 3 pins', throttle branch has an orange interior; it warns 'Do not plug in a connector to the wiring harness if it does not match in color and shape'. Some bikes include a jumper cable, others do not; RadCity 5 Plus needs a 3 mm Allen wrench where the RadRover 6 Plus needs 2.5 mm. By contrast Rad's RadMission harness guide describes the downtube connector as 'black, 10 pins', so the Plus-series loom is NOT the same family as the RadMission/RadRunner external-controller loom. Sold by Bikeshop West as 'Wiring Harness - RadCity 5 Plus', EUR 39.00.

Looks similar, does not fit

Not compatible

The seller's own page excludes the RadCity 5 from this harness's fitment. The RadCity 5 Plus uses the semi-integrated Plus-series loom (black 11-pin main connector, internal controller), which is a different architecture from the 2017-2022 external-controller looms.
