Connector
Rad multi-branch loom; Rad's RadWagon harness guide calls the downtube connector 'the large black connector' and does not state a pin count

Bikeshop West product page 'Wiring Harness - RadWagon 4', EUR 39.00, page shows 'Sold out'. Bikeshop West also stocks a separate 'Wiring Harness - RadWagon 2018/2019' SKU, so the RadWagon 4 loom differs from the earlier RadWagon. Rad's 'RadWagon Wiring Harness Replacement Guide' says 'This guide uses a RadWagon 3 (2019), but the steps will be similar for most RadWagon models' and gives no part number, pin count or connector colours.

Seller's stated fit range 2017-2022 covers the RadWagon 4; note the seller's range stops at 2022 while this generation ran to 2024, so late RadWagon 4 bikes are not explicitly covered.
