Thruxton Identifying Electrical Plugs

Having found the OBD port plugged in to a retaining lug between the battery and the fuel tank, I'm intrigued what two other electrical plugs are beneath the seat of my Thruxton 1200 R?

The first is in my hand in the photo below but normally hangs down beside the air intake snorkel, appears to have jumper wires, and is wrapped in brittle plastic.
The other is white, and clipped to the frame cross-member.

I'm guessing the former might be for an accessory such as the factory alarm which my bike doesn't have, but have no idea at all on the latter.

 

Thanks, Glyn, but I don't follow with certainty what you mean about the white plug.

The diagnostic plug for reading stored codes and flashing software is what I called the OBD port and is the shiny plug just visible at the edge of the photo to the left of the battery.
