Product Description
The Bendix 550265N ET-2 Electronic Throttle Potentiometer Cable Assembly is a replacement electrical component for compatible commercial trucks equipped with Bendix ET-2 electronic throttle systems. Associated with Detroit Diesel electronic engine controls, this cable assembly provides an electrical connection within the accelerator pedal and throttle-position sensing system.
Unlike conventional mechanical throttle controls, the Bendix ET-2 system uses a potentiometer to convert accelerator pedal movement into an electrical signal. The engine's electronic control system interprets this signal to regulate engine speed and throttle response.
The 550265N cable assembly provides a service replacement for damaged, worn, or deteriorated wiring connections in compatible electronic throttle installations. It is useful when servicing accelerator systems affected by intermittent electrical connections, damaged wiring, or connector problems.

The Bendix 550265N is cataloged as an ET-2 cable assembly. Bendix service documentation explains that ET-2 accelerator systems use engine-specific potentiometers and electrical connections, making correct cable identification essential during replacement.
Before ordering, verify the original cable part number, connector configuration, and electronic throttle assembly. Detroit Diesel engines were installed in several commercial truck makes and models, and throttle wiring configurations may differ.
For proper installation, inspect the potentiometer connection and associated vehicle wiring for corrosion, damaged terminals, or loose connections. After replacing the cable, verify accelerator operation according to Bendix and engine manufacturer service procedures.
