Car Alarms: 1990 BMW 750il aftermarket persuit alarm removal, 1990 bmw 750il, bmw 750il

Question
hello,
I have a 1990 BMW 750il with an aftermarket alarm.  I am having issues with the electrical system and I need to eliminate everything I can (the car has 93 OEM electonic systems).  this alarm looks like a mess and I would appreciate any advice in it's removal.
The case has "persuit" on it but no model info.

I have NO keyfobs etc. for the alarm.  a rocker switch was installed under the knee bolster to reset it.

thanks

Answer
Ok, try this.
Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, locate, press and hold in the
valet/overide button, found under the
dash area, (push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.

(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)

This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.

At this point, the only thing working would
be the keyless entry from the alarm,
if it came equipped that way.

Just Repeat these steps to place it
back to usable armed mode.
You may get 2 chirps, confirming it,
and the lights may flash twice as well.

That should do it.
If you want to remove it at this point,
take it to your neighborhood installer
for this, or buy the wiring chart
(Go to: www.vehiclewires.com)
for the vehicle, and reverse engineer it wire
by wire, until safely removed.

Good luck with it.
