Im installing an AutoPage RF-420LCD alarm into a 98 civic coupe. For some reason the keyless entry will not work. Im grabbing the wires from behind the stereo.

I'm using the 3-wire negative diagram in the install guide.

 

3 Wire? There are only two factory wires. What are the three wires on the alarm? I don't have access to an install manual for one of those.

 

Nevermind, I guessed their password and found the install manual.

It looks like you hook the alarm brown to unlock (green/orange) and alarm white to lock (green/white) and alarm violet to ground.

Is that what you've done?
