What wires go to coil?

The wires that typically connect to a coil, such as in an ignition system or relay, include the positive power wire and the ground wire. The positive wire supplies electrical current to the coil, while the ground wire completes the circuit by connecting to the vehicle's chassis or control circuit. In some cases, there may also be a signal wire if the coil is part of a more complex system, such as a fuel injector or solenoid. Always refer to the specific wiring diagram for your application for accurate connections.
