Yamaha 703 Remote Control Wiring Diagram

The Yamaha 703 remote control wiring diagram consists of several components, including the main harness, ignition switch, throttle sensor, tilt switch, and stop switch. Each of these components plays a crucial role in the functioning of the remote control system, and it’s important to ensure that they are installed and wired correctly.

Here is a detailed wiring diagram for the Yamaha 703 remote control:

Component Wire Color Connection
Main Harness Brown Battery Ground (-)
Main Harness Red/White Battery Positive (+)
Main Harness Green Ignition Switch 12V
Main Harness Blue Tilt Switch Signal
Main Harness Gray Throttle Signal
Main Harness Yellow/Black Start Signal
Main Harness Black/White Stop Signal

Main Harness

The main harness is the backbone of the Yamaha 703 remote control system. It connects all the different components and ensures that they function together seamlessly. The brown wire is connected to the battery ground (-), while the red/white wire is connected to the battery positive (+). The green wire is connected to the ignition switch 12V, while the blue wire is connected to the tilt switch signal. The gray wire is connected to the throttle signal, while the yellow/black wire is connected to the start signal. Finally, the black/white wire is connected to the stop signal.

Ignition Switch

The ignition switch is responsible for turning the engine on and off. It’s connected to the green wire of the main harness, which provides it with 12V power. When the key is turned to the on position, the ignition switch sends power to the tilt and trim system, as well as the start system.

Throttle Sensor

The throttle sensor is responsible for sending throttle signals to the outboard motor. It’s connected to the gray wire of the main harness, which carries the throttle signal. When the throttle lever is moved, the throttle sensor sends a signal to the outboard motor, which adjusts the engine speed accordingly.

Tilt Switch

The tilt switch is responsible for controlling the tilt and trim system of the outboard motor. It’s connected to the blue wire of the main harness, which carries the tilt switch signal. When the tilt switch is activated, it sends a signal to the tilt and trim system, which adjusts the angle of the outboard motor.

Stop Switch

The stop switch is responsible for stopping the engine. It’s connected to the black/white wire of the main harness, which carries the stop signal. When the stop switch is activated, it sends a signal to the outboard motor, which shuts down the engine.
