progressive unlock

I currently have Viper 5902 in a 2010 Ford Escape. The door locks are controlled via the Power Lock/ Power Unlock which works fine but I have lost my ability for progressive unlocking. My RF control unlocks the Driver's door and then with the second input it unlocks the remaining doors. I would like to have my Viper do the same.

Studying the literature on the forum here it's still unclear how to implement this. The 2010 Ford Escape has a five wire system. A few clues from the experts on-line would be appreciated.

Thanks for all your help!

Seeing that your original fob has the feature i assume there would be a trigger wire tha would accomplis this, but i have no personal experience with that vehicle so i'll help you as best i can! I don't know how you have your locks currently wired so i'll go by my assumptions! Interrupt the driver's motor unlock wire and wire itwith a relay like this

Pin 87 and 86 - 12 constant

Pin 87@ - ground

Pin 85 - Unlock trigger from the onboard 451 unit

Pin 30 - Driver unlock motor leg

Then take the second unlock wire and connect it to where you had the first unlcok wire previously connected!

Thanks T&T tech.

With your suggestion I can now see how to do this.

As suggested, the unlock command I am now using will control the drivers door motor via relay logic only. Studying my 5902 install manual,  I can program any of my aux channels to be controlled by the second push of the unlock button which will now control the "all unlock" command.

Very simple.

Thanks for the help!

One update to this:

I would think 87A should connect to the BCM side of the driver's door motor not ground.

Ah yes i stand corrected, but in my defense, local ford vans on my side that won't matter seeing there's no internal rocker switch so no need for the drive motor to remain connected to it's original contact, unless you wanted the factory fob to remain intact, although it would be obsolete seeing an aftermarket system was being fitted, didn't i say i had no previous experience on that van!

Implemented this today and it works great.!

Thanks t&t
