FAQ Q&A

A: Absolutely. This switch is a verified cross-reference for the 84340-42020 OEM part used specifically in the Land Cruiser LC100 and Lexus LX470 series for reliable brake signal performance.
Q: Do I need any special tools to install this sensor?
A: No special tools are generally required. It typically involves a simple twist-and-lock or clip-in installation above the brake pedal after disconnecting the wiring harness.
