    That is the diode pack and is located in the headlight bucket. You can see the connection in the attached picture.

    It has three functions:
    - Allow Oil Light to light up when start button is pressed
    - Provide DC current from generator to latch the headlight relay on once motor starts
    - Allow neutral/side stand/clutch safety circuits to work properly

    Pretty sure the UK XJ came with both side stand and clutch cut outs...??

    1980's......but, I think all mine did, originally, may have been 'surgically removed'....(? hmm...might be one of my old ones, lol !! )

    there is a connector in the head light bucket it is green square in US bikes it is part of the starter safety relay makes it so bike does not start in gear with out clutch pulled in. if it has not been jumpered bike will only start in neutral

    if you look at photo from Jayrodoh (jay rode Ohio?) you will see this
