SUCCESS!!!
I got this working! I used the +12 volts to the starter solenoid to pull the relay down and used the driver's door lock signal to ground to lock the locks and it works great. You start the car and the locks lock while the starter motor is turning. When the engine starts, the starter motor stops turning then power to the relay is stopped and the relay opens. The relay is only held down while the starter motor is turning so not a long time with the relay held down. Relay and socket pigtail is $7.00 and is easily found at any auto parts store. The hard part is finding the correct wires to do this. The added ground wire is easy to connect. Just find a bolt and attach the ground wire to that. The door lock wire and the starter solenoid wire are buried behind the interior drivers fuse panel to the left of the dash. You need to take off the panel that the instrument dimmer switch is on and the fuse panel is right in front of you. The bad thing is that the starter solenoid relay is located on the relay panel behind that. To get access to that is the bear. It took me the better part of the day to access it. I removed the wires from the connectors and soldered my new wires onto the metal pins. Then the pins were re-inserted into the connector so no wires were cut. Cut wires always seem to come separated and cause all sorts of problems finding them. This way if anything happens to my new wires, the automatic door lock just does not function, the car stills starts and runs. The door locks will lock even with the doors open so be careful and not get locked out.
If you are contemplating this, get a copy of the wiring diagram for your model from the internet and I can give you what items to look for and find in the car.
I am really happy with how this works and the car should have come with this. So far I can see no problems with doing this, just be ready to disassembly that entire part of the car. Disconnect the battery before you start and know that when you first start it up again, it will take about 10 seconds of cranking before it starts. Don't know why, but it does. It also needs to relearn the fuel trims so the first 10-15 miles of driving are not the same as before but it comes back after that driving.
Be prepared to curse some as you are digging around those relays to get to where you need to be.
