Thank you for the donation.
The wiring diagram shows only 2 wires, Red which is battery cable, terminal "B". Yellow/Light Blue is for the starter solenoid, Terminal "S".
What is the color of the 3rd wire that you are refering to?
If it uis used for tapping power source, it would be attached together with the Red wire.
