One more question,
After I connected the aftermarket keyless brain to the pre-wired harness by splicing the wires, each time I used the remote to unlock the car, an alarm started going (lights blinking for 10 seconds) At this point I had to find a wire called FASD (Factory alarm system disable), fish around to match it with a wire from the harness to stop the flashing lights.
Does this mean I already had a factory alarm????
and, If I did, is it not connected to the harness, or do I have the alarm and the pre-wired harness as well?
I'm confused...please help.
