8man, sorry for the wait. I will admit, that I haven't got the handle forward to lock function working yet. I have it designed via another locking solenoid and cable push/pull system. I need to get the truck running and driving first, then I will finish the lock system.
But for now, I have the inside handle running a cable to the electric actuator and door lock. This way, when you manually open the door from the inside handle, it will unlock that door manually. This will trigger the electric lock and automatically unlock the other door. Both doors are locked and un-locked via an alarm system.
Using these actuators, you can wire all 4 in tandem. When one activates, all 4 will do the same. I don't think one will have enough power to move a door handle. Therefore I will use two on each handle in a push/pull configuration.
