You can set your unlock wire to only unlock the drivers door and then use an auxiliary output to unlock all the doors.
If you need a wire diagram just ask, or someone else can just post it. I am having a hard time finding one that I can post since the one I have is not showing up.

Yes, the above diagram is for normal systems that only have a single unlock and single lock wire.

I'm looking at the diagram and it shows that the 1st unlock pulse and 2nd unlock pulse is coming from two different places in the alarm module . i don't understand where the two different places are . The diagram i'm looking at is from the driver priority picture (in yellow). Please point out were the 1st and 2 nd pulse is coming fromon the alarm.. ------------- "I'm So Loud It Hertz"

For that diagram, you must use two channels as I mentioned in the first reply, and the other diagram I believe will only unlock the drivers door. I believe it is impossible to have two step unlock without this feature on your alarm. You can either use two channels or just unlock the drivers door. Someone should correct me if i am wrong?

Just as i thought . You will either have to use an aux. channel or have the feature in the alarm. I hope that Velocity Motrors or any one else can clear this up . ------------- "I'm So Loud It Hertz"

A recent post made me start thinking again about Drivers Priority Unlock. I do not offer this as a feature unless the customer specifically asks for it, or if they have this as a factory feature on their car and they select a unit which has outputs for it. I am starting this new thread because I do not completely understand this diagram. I can see how it will work if you grab the unlock wire that only goes to the drivers door actuator, but how do you know if you have the right wire? Do the wire databases always give the locations for this wire? This diagram will not work if you grab the wire any other place in the system it wont work as far as I know. I will continue to limit my installing of this feature to those cars which have this as a feature, and the selected unit has the outputs, which most do now anyway, unless someone can shatter my doubt that this diagram will work every time.

If you think about it, what you just said has to be right since the way an alarm with this feature works, is with one press of the unlock button the main unlock out put pulses, and with the second press within 3 seconds, a different wire pulses the rest of the doors. the only way to duplicate that is to use two seperate channels.
