Steering Column Mount Exhaust Brake Control Lever DZ97189584640 Complete Combination Switch With Pre-Wired Harness & Quick Plug Connector

Product Description

DZ97189584640 exhaust brake combination switch is a dedicated steering column control handle for heavy-duty trucks, mainly responsible for controlling the vehicle exhaust brake system to assist vehicle deceleration and downhill speed control. It consists of an ergonomic long plastic operating lever, built-in precise metal contact circuit board, complete pre-assembled wire harness and standard quick-disconnect plug. The integrated metal mounting bracket matches the original steering column installation holes perfectly for stable fixation during bumpy driving. Internal elastic contact shrapnel maintains smooth signal transmission without poor contact after long-term repeated pulling operations. All wire length, plug pin definition and mounting dimensions fully comply with OEM standards, supporting plug-and-play replacement without cutting or re-wiring during cab maintenance.
