    I have a 1981 xj650 and the harness is a mess.i was moving some wires about and the 2 wires that are connected by a green block have come undone from whatever they were connected to under the fuel tank area.theres no obvious connections that I can see

    is this a 650 euro bike (seca) or a maxim? I see you are from Ireland is why I ask

    the green block when under tank is used for fuel level sensor connection from Tank.

    there is also a green block in headlight bucker that connects to clutch lever safety switch

    Yeah the bike is Irish.the block connector was in and around the headlight but the two wires were connected to something in the harness that is under the tank/coil area.i don't know if there were ever used or just redundant

    Does it need to be connected or can it just be unplugged

    if it is for the starter cut off relay and left unplugged the bike will only start/turn over in neutral . this is a problem if you stall bike at a light or stop sign as you will have to shift to neutral before starting.
    the wire from the relay can be jumpered to ground but this will allow bike to start in gear without squeezing the clutch. this can be a problem if it is in gear as bike will jump forward if clutch is not pulled in. you will have to get into habit of squeezing clutch before starting .
    (if wires are connected to connector those wires can be jumped)

    if it is the green connector that is used for fuel meter guage it is ok to leave it unplugged. do you have a fuel guage?
