  If you have a 2009-2015 Lexus RX and you are curious whether or not to connect your OBD2 port wire (it runs from the factory OBD2 port to the main Hamilton harness), here is the answer:

  • 2009-11 RX OEM Monochrome Screen: OBD Yes
  • 2009-11 RX Mouse Version: OBD Yes
  • 2012-2015 RX Knob Version: OBD NO
  • 2012-2015 RX Mouse Version: OBD Yes
