Yes, it applies even if you don't have a Lexus phone. Your car was pre-wired at the factory for a Lexus phone. The phone was a dealer installed option with components that plugged into factory pre-wired connectors in the trunk, under the center armrest and on the steering wheel. It played the phone call audio through a door speaker, automatically muted the radio and lowered the HVAC fan speed during a call, etc, etc. Quote Link to comment Share on other sites More sharing options...

Jesslynn2185 Posted November 13, 2013 Share Posted November 13, 2013 I need a wiring diagram or location of the parking break wire for stereo installation on a 2000 Lexus GS400 Nakamichi sound Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted November 13, 2013 Share Posted November 13, 2013 You should not have to connect it - just don't watch videos while driving! My aftermarket Kenwood DDX470 headunit (replaced a Nakamichi headunit in a 2000 LS400 using the Nakamichi amplifier) is not attached to the parking brake wire. If you really want to connect it, look for a switch at the parking pedal or lever - easier on my LS since the switch on the parking brake is exposed.
