So I bought the car from my pops since he couldn't figure it out. Since I bought it I noticed several things. First the rear view mirror lamps would turn on spontaneously so I disconnected that batt drained in about 2 days. Then I bought a new batt. 2 days later dead. Another thing I noticed was the remote with keys only lights up lights when locking or unlocking and horn chirps but does not actually phyisically lock or unlock car. Then finally today I tried to reprgram fob but did go though the cycles as it should but still makes car horn chirp with double depression of lock button and side lamps blink. Today I also noticed that none of the interior lights light up anywhere I checked all fuses they all check out o.k.. The very last thing I noticed and I'm thinking this maybe the culprit, since I bought the car I thought this plug-in port where knees would be I thought it was the OBD2 port but it is not. Right to the right of this mystery port is the actual OBD2 port. So this mystery port has a near neon green light that is always on even when key is not in the ignition and with everything shutoff and doors closed. For a second I thought this maybe a brake diagnostic but I dont think so. What could this port be? If it helps on the bottom side of this plug-in it has a ATS on it. Anybody know what it is? If not I will dive into researching this port next week. I think this green light is draing my batt. Or atleast I hope this is what it is any help would be great. The car is a 1996 Camaro Z28 A4 100% stock that I'm aware of with 130, XXX miles odometer.

Don't know what it is, but it did not come from the factory.

Does it look like something fits into it like a flad blade key like object might fit into it? I had a car once that had a anti theft device like I described...It had a green light on it also.
