A lady wants me to install either a viper remote start or a python remote start (samething)on i believe it is a 1997 Lexus RX300. not sure if the year is correct. but i wanted to see if there is anything i need to know before i start, or will it be like installing on a toyota? if it is a '97 or a '98 i need the wiring diagram ( i only found '99 here).
thanks in advance
98 Lexus Rx300

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.

Is up to the installer to test all wires with a DMM whenever possible.
yeah, theres a crazy doorlock/factory security interface you need to do in the drivers door, with 3 wires, a relay, and diodes. and also the autolights will stay on after the starter shuts off, so you need to pulse a doortrigger to shut off the lights after the starter shuts down. if you want a copy of the diagram email me and ill send it to you
