I recently purchased an Upper dash unit for my K75RT. But, it didn't ship with the wiring harness. Can anyone tell me what the harness or harnesses look like and what type of connectors they have? I don't want to spend the money BMW wants for it and have talked with the seller who has a complete wiring harness. He''ll ell me the pieces I need but doesn't know which piece fits what. I know there is a connector under the tank for the gauges per the schematic I just don't know which one.
