avital 4113 & pkall lexus es330

Yes, I should have also said what Kreg said. If you leave the programming in default, the blue/white and blue wires from the Avital do the same thing. One should be used to trigger the PKALL; the other is used to trigger keysense. As far as testing the factory alarm without making your neighbors crazy, a good way to sort of pre-test it is to activate the remote starter with the driver's door open. If you hear the key-in-ignition chime come on, you can be pretty sure you've connected to the correct keysense wire. You'll still want to go ahead and fully arm the alarm and test again, but I always listen for that key chime just to at least tell me I'm on the right wire.

You are already using the 4113 Dark Blue (-) Status Output for the PK-ALL.  If you don't use a diode to isolate the Keysense wire, every-time you insert a key into the ignition switch, it will supply a (-) signal to the PK-ALL GWR Input wire and turn it on. If you aren't using the Avital 4113 Blue/White 2nd Status wire ( for Defrost ), connect that to the cars' Keysense wire and keep things isolated.

Yes, I could use the Blue/White 2nd status wire for the keysense instead of the Blue.  So it will go like this:

4113 Blue Status  -to-  PKALL Blue/White

4113 Blue/White 2nd Status  *AND*  PKALL Green  -to-  Vehicle Keysense

Thanks again for your help.  I don't know where else I would turn to for this information.  I have installed Security/RS (Old Viper 800HF / Valet 551T / 555U bypass) before in my own cars ('92 and '99 Accord LX) but never had to deal with factory alarms or the newer data transponder bypasses.

Just to be certain:

I assume there is no need to diode isolate the keysense when connecting both the 4113 2nd Status Blue/White and PKALL Green to it?
