    Sorry I took so long to reply to ya'll. I seem to have bumped a size error on the newsgroup server.
    This will cause both rear turn signals to light when the rear brake is
    applied.
    The turn signal will still blink when the turn signal is activated. I have
    preformed this on various makes over the past twenty years.
    Obtain 4 6 amp 40 volt (Motorola brand is MR760 High Current Rectifier
    Diode, carried at Radio Shack).
    The diodes are connected as in the attached picture. The diodes are marked
    with a single paint band. This band corresponds to the line in front of the
    triangle in the drawing.
    Make good mechanical connections(twist the leads together) and then solder
    the diode connections. Add wire pigtails at A points. Use the same or larger
    gauge wire as the bike's wiring harness. This will make it easier to attach
    to the original wiring harness.
    You have to splice the rear turn signal wiring harness. I usually choose a
    point on the sub-harness under the seat. You can find your signal wires with
    a test probe, test light, etc...The brake connection can be made by joining
    the brake wire, it does not have to be spliced. On the older bikes, the
    connectors were standard bullet connectors and you could create a plugable
    unit. My bubf has a small non-standard connector so I cut the wires and
    spliced it in.
    Insulate the diodes after the soldering. I usually wrap the diodes in tape
    or heat shrink tubing, then place a piece of rubber inner tube around it.
    There are plenty of nooks under the seat to tuck this into (note: mounting
    location may determine how long the pigtails have to be).
