Hello everyone,I have put a new stator on my v4115 76 evinrude and have hooked up my rectifier and stator correctly on my terminal board but have a purple wire which is live with ignition on,a purple/white wire which i know is for a choke solenoid and i have a sensor on the top of the powerhead with a purple/yellow wire and a purple wire.can anyone tell me what that sensor is for? and also how they tie in on the terminal board ? I have a wiring diagram but it doesnt show those wires. thanks-cruizer
