This guy (SVXdc here on the forums) I vaguely remember also selling an adapter to plug into the stock security plug. That will take care of about 90% of the necessary wiring (basically everything other than the actual remote start wiring at the ignition or wherever).

Do it yourself if at all possible, whoever did the wiring of a remote start/security system into my black car many years ago (before I owned it) really butchered the wiring and created a short that caused the battery to drain when the door lock fuse was in. After a few months the "fix" was to disable the aftermarket system (still leaving it zip-tied in place and plugged into everything), remove the door lock fuse, and replace the ignition itself! So in a few months it went from having a perfectly fine, working stock security system to having two different keys for the ignition and doors, and no power locks.

Do not underestimate the damage that the amateurs at the security/audio shops can and will do to your car.

You have a 96, so, yes your security module is under the rear deck between the rear speakers. However, to change the speakers, you must remove the top cover for the rear deck, but to change the security system, you should only need to remove the bottom cover, which is in the trunk.
