Wiring Help - Identification

[Dieseldog]

Hi,
Started to put the wiring harness back on 89-Reg F2. Forgot all about this when I stripped it off , what is this connection for and any ideas why its had a loop back to itself fitted? Wire colours are black & blue with yellow stripe. Seem to remember the earth wire being broken before I removed the harness.
Looks like the blue/yellow wire connects to a small black box mounted on the rear mudguard. What's the black box? In the 2nd picture.
Cheers Nigel
