Hi, I have a van that has a factory alarm but i want to instal another with sensors in rear and louder siren.
Firstly if i instal new door pins for new alarm is it ok to have two alarms?
Secondly the alarm has the out put for the pins but does that go to them with no other cabling (pins look one terminal) so when pin (door) open it goes to ground and the alarm knows this from its wire connected? Or does pin some how need other wiring other than the output from alarm?
Thanks
