Rad multi-branch loom: silver metal threaded round display connector at the handlebar end, separate throttle, headlight and left/right brake connectors, large black main connector routed through the downtube

Sold by Bikeshop West (NL, last original Rad parts stock) as a model-specific SKU: 'Wiring Harness - RadRunner 1', EUR 39.00, page shows 'Sold out'. Rad sells a SEPARATE harness for the RadRunner Plus ('Wiring Harness - Runner Plus', EUR 39.00) and for the RadMission (EUR 34.00), so the RadRunner 1 loom is not interchangeable across those. Rad's own 'RadRunner Wiring Harness Replacement Guide' (support.radpowerbikes.com) confirms the harness is a Rad replacement part and names the branches that must be unplugged: 'Unplug the throttle, headlight, and both brake connectors from the wiring harness by pulling the connectors directly apart without twisting'; the display connector is the silver metal threaded type. That guide states no part number, pin count or wire colours.
