FACTORY ALARM DISARM

YELLOW/BLUE (-)

IN DRIVERS KICK PANEL, WHITE PLUG

To disarm the factory alarm you pulse this wire with the aftermarket keyless entry. You use the wire coming off your keyless entry that say factory disarm. If you don't have that wire, you need to split your unlock wire with 2 diodes(band facing module). 1 wire goes to your unlock wire the other goes to the disarm wire. Usually you will test this wire by turning the key in the drivers door. when you turn the key to unlock you will get a negative signal on that wire.

I am using a K9 Mundial SS there is no wire that specifically says anything for disarming the factory alarm is there any other wire I could use?

Thanks

the k9 should have a factory alarm disarm output. If not, use the unlock output and connect that to your factory disarm.

you will diode isolate the wires to prevent backfeed on any wires.

85 - constant 12v
86 - negative lock output
87 - ground
30 - to lock wire on car and to factory disarm wire.

put the diode inline with each wire (cathode) towards relay

Can I hook it up to any output wire?
