02 Accord remote start 2 step lock/unlock

Im installing an Audiovox APS996A in my 2002 Honda Accord EX V6.  I have been able to find everything except for 1 wire.  Any help would be apprecited.

I have the 2 step unlock from the factory.  With the car locked/armed, if you touch the factory unlock button on the remote once, the drivers door only will unlock and disarm the theft system.  Pressing the unlock a second time within 5 seconds will unlock the rest of the vehicle.  I have found the re;ay module in the passenger side fuse pannel with no problems and isolated the orange wire for unlock/disarm and Blk/Blu wire for lock/arm.  The problem is, this does all of the doors. 

I know there must be a way to isolate the ground input for the dirvers door only.  I mean, I can hear the same relay box click when I use factory remote for the 2 step locking.  Has anyone found the wire I can tap into so that I dont have to wire in a new set of relays?  The instructions with the audiovox unit show the wiring to put your own relays in but I would really like to use the factory ones.  There must be a way to use factory relay setup, I just cannot seem to isoalate it... I have been all over that fuse pannel an cannot find the darned thing.

This is exactly the method Im trying to avoid.

I dont understand why if the factory system has the relay inplace for this, there must be a way to tap into that????  I agree that your way would work but I really want to avoid adding a relay.

Am I wasting my time trying to figure this out, or do you agree that it must be possible?

Auex,

Thanks for the info.  As per our discussion, I cannot achieve this the way I want to do to the fact that the factory keyless entry module offers this 2-step unlock and there is no way to "tap in" to it.  I will use your recomended method above...>Thanks again.
