    excellent graphics Cableguy! I can't think of much to add to that, except for maybe easy tap-in points for the turn signal lights. I'll get to that later though.

    4 Way Systems

    Flat molded connectors allow basic hookup for three lighting functions; right turn signal, left turn signal, stoplight / marker and a ground.

    Same as 4 way system listed above but adds a extra red or black auxiliary power wire.

    6 Way Systems

    Round 1 1/4" diameter metal connector allows 1 or 2 additional wiring and lighting functions such as back up lights and electric brakes.
