Silencer alarm system uninstall

I still have the duster haha just a bit of project going on. Hopefully will have more time when I have my ME degree in a month.

1999 Plymouth Grand Voyager with 3.3L V6 .
I honestly don't have any diagrams except ones that tell me what the relays are under the dash. I have tried to look up this model alarm and It seems to be impossible to find install instructions.

Funny what happens to "reliable" transportation.

Thanks though I'll be spending some time tracking things down and will check back later.
