Had an 05 optra in today for an r/s install. Everything went smooth, no immobilzer of any sort. As I was delivering the vehicle back to the customer I remembered something about a content theft alarm. I didn't do any disarm of any sort and sure enuf, the alarm went off upon remote start after locking with oem transmitter. Where is the disarm wire on this car and what do I have to send to it to work for both r/s and unlock.

Factory disarm is Lt. green , (NEG)- in the drivers door boot. It must come thru the door...... but Astro does NOT say where it goes.
