OEM: 8981404870, 36750-SMA-003, 8-98140487-0.This product is a car brake light switch, which is a precision repair accessory used to replace damaged switches. This brake light switch is strictly compatible with Isuzu Dmax TFS87 chassis model, and is particularly suitable for vehicles equipped with the 1.9TD RZ4E engine from 2016 to 2020, ensuring a perfect match with the vehicle's electronic system. Its core function is to turn on the circuit to light up the brake light when the brake pedal is pressed, and at the same time send brake signals to the engine control unit, transmission control unit, etc., to achieve functions such as brake light on, gear shift lock release, and cruise control cancellation. Adopting a 4-pin interface design, with a working voltage of 12V, it is a normally open switch. The installation thread specification needs to be perfectly matched with the original brake pedal bracket to ensure accurate and reliable signal triggering. The switch body is made of high-temperature resistant engineering plastic and metal contact materials. During installation, it is necessary to first disconnect the negative terminal of the vehicle battery, unplug the old plug, screw the new switch into the fixing hole in the correct direction, reconnect the plug, and test whether the brake light function is normal.
