5.3 OPTIONAL BUZZER ASSEMBLY CABLE
The LMU-26xx can be used to provide a connection to an in-cab buzzer to provide driver behavior
feedback for specific conditions, such as hard braking, hard acceleration and exceeding a defined speed
threshold. You must connect the Buzzer Assembly Cable (P/N 4C765) to the LMU-26xx Power Accessory
Cable (P/N 5C260 or 5C261) and mount the buzzer to a metal or plastic surface of the vehicle. This cable
can be used in combination with the Switch with LED Button Cable (P/N 4C764).
Note:
To install the Buzzer Assembly Cable with the LMU-26xx, you must order the Power Accessory
Cable P/N 5C260 or 5C261 – See Section 3.1 “Available Wiring Harness”.
