Ignoring the Troll...
OK - So I didn’t look properly; there is indeed a connector on the rear underside of the light - you need to get underneath to see it. Connector is well hidden compared to the old bike foglight connector.
Couldn’t work out how the connector came off, so unbolted the light for a better look at the underside. I found that by inserting a flat blade screwdriver as per photo below, the connector pops off. The tab that the screwdriver lifts up can be clearly seen in second photo. Kinda neat that the tools under the pillion seat are all you need for the job.
I just wonder why it needs 4 wires do when normally only 2 are needed to power a light. What do the additional 2 wires do?
