    Does anyone know exactly what disconnecting the white wire on the xb9 does? What is this wire for?

    I just reran a bunch of my wires and one of the headlight wires is white.

    So I imagine it is the low beam and it would then allow you to drive with no running light. Just a guess.

    white wire in grey plug connects to a sensor which keeps the exhaust within environmental standard.

    if you have a race ecm, this does not matter, since it is not taken into account by the ecm

    instead of cutting it, do this and seal of the hole in the connector to protect it.

    I unplugged this wire and it didn't really seem to make a difference, so I just plugged it back in.

    plz note, that if you have a race ecm installed, this mod is useless.

    why?
    cause the race ecm doesn't send a pulse over the white wire.

    why not?
    because the signals sent over the white wire is for environmental related/fuell emission laws, which limits the performance of the bike.

    If I pull this wire is there anything else I need to do before riding?
