Bought the motor on EBAY, with controls. When I got motor there was Shift/speed control, with cables. One large cable, from engine, with 4 different connectors and 2 cables with 3 wires. No key or start switch. No choke or fast idle control. None of the wireing will connect to my boat. I have ordered a EV. manual, but forum posts indicate it will not be much help. Question is --What is the minimum I need to see if the motor will run and where might I get the instruments and controls I need?
