I was wondering if there was a way to instatll a shock , or radar senor with my Factory Nissan Alarm, it is in a 2003 Nissan Sentra SE-R Spec-V
any help would be greatly appreciated
Thanks

its possible by connecting output triggers of sensor to door triggers they absolutly have to be diode isolated
you will need a sensor that powers up with 12 volts not all do so research this before you buy one to make sure it takes 12 volt input to power up
i cant remember if that car has neg or pos door pins if pos you will need switching relays because the trigger output will be neg
Nice car, really should have aftemarket alarm.
Anyway.
wiring diagram
bulldogsecurity.com or any universal radar sensor will work with 12v in.
Personally I would connect in center console area and wire as follows:
radar unit:
positive - 12v constant
negative - to the e-brake switch or to IGN wire
output(1) - to pin 85 on relay.
output(2) prewarn - no connection
85 - to full alarm output on radar unit
86 - constant 12v
30 - ground
87 - to the door trigger wire (red or RED / white as per above)
87a - not connection
The radar unit has to be disabled or it will keep sending the output to the door wire 100% of the time.
Connecting negtive of radar to IGN wire, the IGN wire will have a ground (sort of) when it is not on. When the wire gets power ground will go away and radar will turn off. I like the e-brake switch better since it is a true ground, when the brake is up the radar is active. Brake down and radar is off.
prewarn could be hooked up to the horn BUT since it would go off the entire time you entered the vehicle it cannot be used.
Here's an alarm for $40 on ebay. Another $20-30 for radar and you have shock and radar plus siren, outputs for trunk release, windows up\down, and keyless entry
Viper look alike
