How to connect: RADAR INTRUSION DETECTOR Is it possible to connect this to the Trans Am -99, factory alarm system?
I have got this unit:
RADAR INTRUSION DETECTOR
"This model emits a high-frequency energy field that immediately detects intrusions. Ideal for open cars, boats, etc."
http://www.velleman.be/ot/en/product/view/?id=2827
http://www.electronicsnmore.com/prod...oducts_id/1206
Perfect when leaving the car for a while with the t-tops off.
Here is how is should be connected according to the manual:
The best moutning is beween the driver and the passenger seats,
or in the centre of rear seat area.
RED WIRE
Connect the red wire to a constant +12VDC power source.
BLACK WIRE
Connect the black wire to the good chassis ground.
BLUE WIRE
The blue wire will provide a negative output when the sensor has been trigged.
Connect the blue wire to the alarm's negative input.
If more then one senor is installed, each senor's negative output (Blue Wire) must be isolated with a 1N4001 diode.
So, the blue wire, is it possible to connect this somewhere to the factory alarm?
Negative output....
Maybe to the shake-sensor (located over the the right backwheel)

Usually these sensors have two output wires - one for "warn away" and one for "full alarm". In your case there is only the one for full alarm. Mount the sensor as close to the center of the car as possible. Under the console on top of the airbag module is usually a good place. Connect your blue wire to the light green wire in the bottom row of the blue 32-pin connector at the BCM (bottom row when viewed with the connector locking tab on top). The light green wire is between an orange with black wire and a black wire. This is the full alarm signal wire from the factory shock sensor.
If you want to upgrade to a dual-zone proximity sensor, the DEI 508D is about $45. DEI is the company that makes Viper alarm systems.

Thank you!
Is there also a wire for "Warn away" on the BCM, which wire?
The unit needs +12 and ground, is there any wire that I can connect it to so it´s only ON when i have the alarm activated?

There is no "alarm active" signal wire on the factory alarm like there is on most aftermarket alarms. So no, you can't really hook up the sensor to only have power when the alarm is active. However, it draws so little power that you don't need to worry about using a battery feed unless you leave the car for weeks at a time. Also, even though it's always powered, it won't actually do anything unless the alarm is on.

The size of the field is adjustable. I have a dual-zone perimiter sensor that is adjusted so that the inner zone is entirely within the car's interior and the outer zone extends about 6 inches outside the car. The outer zone provides a warn away chirp of the alarm if someone brushes up against the car. The inner zone provides full alarm activation if someone reaches inside (say, when the t-tops are off).
A single zone sensor should be set with the zone entirely inside the car so that you don't get a lot of false alarms from people walking by in a parking lot.

Thank you WhiteBird00 for the answers.
And for jwhert
From the manual:
This sensor detects mass movment within the RF-protection area and responses to large objects such as human arm or leg.
This sensor is not disturbed by heat expansion, wind or falling leaves.

There are also infared detectors used for door openers, but I don't think that they are used for car alarms though, as they are not sensitive enough.
