I replaced an fc420v on an older model scag manual start with a new version of the same engine. Almost everything is identical except for the wiring hookups. Where there used to be a plug on one side of the older engine, there now appears to a a screw on the other side of the mower near the throttle which can recieve a wire. Basically, since it's completely different I have no idea how to hook up the wiring. Below are pictures of the wire connections, the actual wires I have coming out of the circuit, and the wiring diagram from the manual. Any pointers anyone could pass my way would be really great. Thanks!
