Good quality junction box with linked electrical terminals, made by Scootopia. as used originally on the 12 volt later SX and GP / DL type was linked, the Li, TV and early SX's used the non-linked type. These affix to the left hand rear outrigger and are ideal if you have DC power, are running a battery or if you are using gadgets ( cigarette lighter socket / USB / extra lights Etc).
  As you can see from the 1st photo, the Orange, Brown and Purple are joined.
 
Please note: These do not come with the rubber cover, but they are available here.
