09 Altima Remote start/alarm

Check the last few pages of the install guide, there might be SOME DB-ALL 2 programming mods, or hardwire the lights. I can't see any way around carrying the fob, that makes two of us!

I have to check and see if there is a starter or shutdown feature incorporated into the dball. If so, i will just leave a key fob in the car somewhere to act as a workaround. Since the alarm will always be on even when the car is running. I could always use the siren or horn output to trigger a latching relay to interrupt the clock or data wires from the key port connector,(or the neutral safety wire) so if someone breaks into the car, the car will not remain running. If there is no starter incorporated in the dball, i will use a relay to only power up the factory fob when the ground-when-armed wire is off and the ground from the seat belt connected wire is grounded. That way you have to disarm the car, get in the car, attach your seat belt, then you can do take over. Not many car thieves would think to put on their seat belt before attempting to drive off. Off to design a circuit. I'll let you know how it works and what actually works.Lee Buxbaum

Good thinking reference the last line.

i used a micro relay, a button battery holder, and the factory key fob. Going out at lunch to locate the seat belt wire and test it out.Lee Buxbaum

unless the seatbelt is fastened, the circuit isnt operable.Lee Buxbaum

Just occurred to me, for heaven's sake use a DMM when you test that seat belt, the wiring might be data!

i looked up the wiring online. It's a grounding switch input to the cluster, but yeah my fluke meter is all i use.Lee Buxbaum
