Car Alarms: disable stock alarm on 97 ford mustang, side kick panel, ford mustang

Question
i have a 97 mustang and everytime i take out the key the "theft"sign starts blinking and sometimes the alarm goes off.How can i disable the alarm forever?i tried the overdrive thing and it dosent work,i unplugged all the wires from the trunk that leads to the Anti Theft Control Unit then the car didnt want to start up again is there a fuse that leads to the horn that i can take out to atleast stop the horn?

Answer
ok, locate in the drivers side kick
panel area, the wire pack containing
the dark green/purple wire, and put it to the chassis,
grounding it out completely, & disarming the factory security system. You can also locate it at the Anti Theft Control Unit located left rear of trunk behind trim panel.

That will solve your issues.

Good luck.
