current from the battery to the charging circuit, starting
circuit, and senders attached to the engine. It also supplies
the current to the main frame wire harness.
Transmission Wire Harness
The transmission wire harness (Figure 3-8) supplies
electrical current to transmission solenoid valves, speed
sensor, and oil pressure sender. It connects to the ECU in
the instrument panel.
Main Frame Wire Harness
The main frame wire harness (Figure 3-9, Figure 3-10, and
Figure 3-11) supplies electrical current to operate the
electrical components attached to the main frame. It also
connects to the instrument panel and engine wire harnesses.
Instrument Panel Wire Harness
The instrument panel wire harness (Figure 3-12) supplies
