07 azera door lock problem

Recently I installed an Astro Start 4204 remote start/entry system into a 2007 Hyundai Azera.  Everything went smoothly except I cannot get the power locks to function with the Astro Start remote.  I have 3 different websites where I get wiring information and they all agreed (surprisingly) on 2 wires inside the driver's door, a BROWN / orange to lock and a pink to unlock.  However, when I attach to these 2 wires, the door locks will not operation.  If I lock the doors with the factory remote and then hit the 'lock' on the Astro Start remote, I can hear the actuators inside the doors trying to respond by locking the doors but when I hit 'unlock', absolutely nothing happens.  The same is true if the doors are unlocked and I try to lock them.  Also, if I lock the doors with the factory remote and then push the unlock button on the FACTORY remote, the driver's door will unlock.  If I then push the unlock button on the Astro Start remote, the remaining 3 doors will unlock.  Is there another wire somewhere that I have to pulse in order to make the locks respond when I use the Astro Start remote?  Nobody I've talked to has any idea why it doesn't work.  I'd really appreciate any help I can get.

Here is a link on how to wire it up. http://directechs.com/techtips/pdfs/resources/security/directed_techtips/1300.pdf.
