Hello

I read a topic on this about passlock doing a search, and it was metnioned that if your remote start does not have this connection i cna still use my passlock bypass module, but i need some relays to make it work. I need to know the info on how to wire this up in my 2000 grand am. I got everything else, just not a wire on my remote start that would provide a - when on.

Thanks

hmm.... lets see, you could do some polarity floppin with a relay... i guess take an ignition wire to pin 86 on a relay, then ground 85 and 87 together, then take 30 to the wire you need the (-) for.

the ign will be the trigger to activate the relay and ground will go from 87 to 30.  pretty simple.

just go out and use a 555l, hook it up and it learns the resistance by itself saving you the pain of hooking up two relays.

i already have the bypass module for passlock, kinda same thing as the 555L, i just don't have a Negative when running wire on my actual remote start...that would be the wire that would activate the bypass when remote starting.

So if i hook it up like posted with that relay, it will burn on the bypass and then it would attempt to start correct? Thanks

You can not do this because the relay will not shut off current to the bypass module when the driver takes over remote start after they hit the brake. This means that there will be two Passlock signals going to the Passlock computer whenever ignition is on. You have to wire in a switch  in line of the ground( to pin 30 ) or ignition power ( at pin 86 ) to break the current after you insert the key into the cylinder. As you press the brake pedal, turn off the switch. This is a manual way of doing it, if you want an automatic way of doing this you will need to wire in more relays that will cut current from pin 30 of the first relay and have it triggered by the brake pedal or e-brake.

would you mind explaining how to wire these relays together? a diagram would be awsome. Not very good with relays and how they work, good with wireing them together though :)

Only problem with this wire is that the module will always be on when the system is armed. This means that the Passlock is disabled when the alarm is armed and when it is set off, the wire is still (-) so someone can still steal the vehicle because the passlock bypass system is still engaged.

I know on like the omega systems they have a 3rd ign. output that is like a (-) pulse.

but it will still remote start right? just would go without having passlock protection..i can live with that :)
