Step by Step DIY for UNGO MS8300 
Created by Ziggy updated 6/2000

The UNGO MS8300 alarm is a great alarm that you can install on your Z3. 
There are advanced features you can wire. They are one touch window roll 
up and garage door opener activated from your remote.  These features need 
relays but are fairly simple to wire if you think you have use for these 
I would consider them, time to install is about 4 hourse. Here are the 
features you will have with the basic:
1. Remote lock/unlock
2. Arm/disarm confirmation from siren and hazard lights,
3. Auto lock on ignition. ( 10 second delay)
4. Auto unlock on ignition
5. Auto rearm if trunk or hood not opened or ignition not turned on
6. Dual stage shock and motion sensors with "warn away" feature
7 Shock and motion sensor sensitivity adjustable /defeatable from remote
8 Double lock on arm (can't open doors inside or out without remote or key)
9 Tripped zone identification on disarm
10. Doors, radio, hood and trunk protected.

I installed the alarm in a 96 Z3 1.9L to my knowledge 1997 would be identical 1998-2000 
your choice on where to put LED and Valet switch, there is information on this in the 
archives. The CPU may not fit in the place I describe and you may 
have to alter your CPU location. I did this to help my fellow Z3 enthusiast 
use this information at your own risk, damage to your vehicle electrical 
system can occur.
