How can I hook up my wiring on a Stihl ms 310 chain saw?

I have rebuilt a stihl 310 and cannot remember where the wires are connected. Specifically the 2 wires (green/yellow) on the black solenoid(?) on the black starter rope side. There is a small screw but I cannot find where to attach. Also the 2 wire that go into the handle trigger mechanism. There is a black and yellow. One more thing is the circular flat metal piece that circles the hub on the opposite side of the saw and attaches as a small horizontal post pressed into the housing and ends as a flat tip in the anti kickback shut off mechanism. It has a small keyhole shaped hole in it and sits under the small metal arm attached to a spring. Does it get hooked up to anything?
