Car Alarms: crime stopper alarm/ k-9 remote deactivation, crime stopper alarm, fuse block

Question
I recently purchased a 1990 chevy g-20 van with the crime stoppers alarm including the K-9 remote.first the siren was ripped out by the last owner,there is a small black box 1"square mounted on the center of cowl panel under hood,wires cut,there's a long black box about 4"long under dash,is this the alarm brain? I would like to just remove the system completely instead of just de-activating it.This is a custom van with alot of additional wires (representing a birdsnest)running directly into fuse block,what are the specific wires supporting the alarm system so I dont remove or create a bigger wiring problem that Im already facing. Thanks guys!

Long conversation to get this done right. :>(
Please try Robert in my forum: WWW.INSTALLSUPPORT.COM

He can go into this in depth with you
to try to nail down the wiring issues so
you can affect repairs.

I try to keep it to a 1 or 2 responce
session on ALLEXPERTS and you will need more attention
on this project to extract it correctly/safely.

Good luck.
