I am trying to install my JVC dvd player with a flip down monitor in my 1999 RX 300 but couldn't figure out the wires yet. does anyone know the wire colors (speakers, power, accessory, etc.) for this lexus model? my plan is to cut the speaker wires and run them from the JVC dvd player and tap into the power, ground, and accessory wires. thanks.

Notes:
NOTE: This vehicle has an immobilizer system that needs to be bypassed when adding remote start. Use DEI part number 555U or 555F. *1 Located in a gray 15 pin plug. *2 This wire goes to the key cylinder illumination ring and reads the delay. *3 Located in a 20-pin plug, low in the kick panel. Test only with a digital multi-meter as some of the multiplex wires in the car are white/red. *4 In the engine compartment, under the relay box on the drivers side in a gray 17-pin plug, pin #1 *5 In a 10-pin plug. *6 Coming from the cluster to the cruise control computer, it is located just above the drivers main fuse/relay box. *7 This is the ignition key sense wire. Using the status output wire from the remote start to ground this wire will disarm the alarm without unlocking the doors. *8 The amplifier is under the rear seat.

you should be able to find a wiring harnes that plugs in to the deck and is made for that model Lex. ask a car stereo shop ( a GOOD shop)

Wish it was that easy. I still havent found one myself.

Nak system is based on cd changer (where the glove cmpt. for other cars is), head unit, display, amp (under/near rear seat), sub under passenger seat.

Signals from cd to head unit are differential (l+, l-, r+, r-) and non standard.


Tapping in, is not easy as plugs are not available [let me know if there is a source for male-female pair for the cd changer]. Your best bet would be to bypass the head unit and go to the Amp directly.

Lexus are not easy to add on to.
