Here is what I have found so far in playing with the failed lotus unit; pin 9 is battery +, pin 10 is battery -. Pins 2 and 6 are ground signals from the door lock switch. Using a 9 volt battery hitting 2 with ground triggers a momentary click of the relay further from the connector, hitting pin 6 does nothing leading me to believe that the closer relay has failed and that must be the one to unlock the doors. Pin 7 and 8 are signals to the door locks. What is interesting is that checking voltage off them with the negative probe they both show nine volts. Grounding pin two momentarily drops voltage from 7 but not 8. I would have to assume if pin six worked hitting that would drop from pin 8.
So.....to lock the doors it appears that pin 7 gets + and 8 gets -, it's reversed to unlock them. Now to just try it on the car. It always helps me to write these things out for me to sure it makes sense, then you guys can check it as well as use it as a reference if this ever happens to you
Edit: that plan works by the way, just tried it out. Now just going thru the Saab unit to figure out which pins to move to where. As long as this cdl module is not doa, should have fixed this for $12
