aftermarket alarms
I bought a 94 ls400 and the only key o got was the service key. I want to get the alarm working and I am concerned about getting an aftermarket alarm with the existing Lexus alarm installed. Please help?!

I've been installing professionally for awhile now and I have a 94 LS400. You can integrate an aftermarket quite easily into this car. Hell I even wired in the gas door pop lol. If you need any help in wiring post up!

Well usually aftermarket equipment is not meant to bypass so much as it is integrate if you're using the factory wiring. The lock wire is Green/Yellow and the lock wire is Green, both are negative triggers which means they go to 0v when active or pressed. Now when the right lock wire is tapped the factory alarm and the aftermarket alarm are both active, and when the correct unlock wire is tapped then the factory alarm and the aftermarket alarm are both deactivated. ALWAYS USE A MULTIMETER NO TEST LIGHTS PLEASE!!!
