i finished installing a viper 5900 into an 04 lexus rx330 and everything is working except i have a couple of problems/concerns. first, i connect the 3rd ignition output (assuming it is the same as status output) to the keysense wire to disarm the factory alarm when remote start. the steering wheel tilt down when it remote start but it will not tilt back up when the remote start stops. is that how it is and is that a problem? second, i got all the door pins except for the left rear door. tech info say it is black, pin 7, in a 13 pin plug on the right side of the fuse box, but i can't find it.

The driver door trigger is blue at the BECU, 16 pin plug, pin 14. The passenger door is blue at the BECU, 28 pin plug, pin 23. The right rear door is gray at the BECU, 16 pin plug, pin 16. The left rear door is black, pin 7, in a 13 pin plug on the right side of the fuse box. Use all four wires and diode isolate each.
The BECU (Body ECU) is attached to the back of the fuse box under the driver side dash.

For the 3rd igntion you would use the Pink wire that is part of a small harness that connects to the back of the relay pack. Use a relay for this.
