When I got my autopower it had turnsignals mounted already. When you look at the fairing there should be two holes (where the mounting brackets are) the front turnsignals mount here (on the outside) the one hole the wire comes through and the second hold is for the mounting screw (already there).
The rear turnsignals mount on the seat platform (under the toolbox) far back to the rear of the ped with again two holes one for the wire and one for the mounting screw.
So far as the wires are conserned I did not look for the colors but they should already be bundled in the wireing harness, you may have to take the headlight off and you may have to look in the frame tube under the seat.
the only other thing that should come with the signals would be the switch which is a 3-way switch (left-off-right) which mounts to the handle bar with a u-bracket.
If you need the wiring diagram I will scan it tonight and upload it tomorrow, just let me know.
