I also tried disconnecting the both the lock and unlock wires and testing the voltage and got barely any, if any, readings. I tested the voltage in this case by connecting one probe to the output wire and the other probe to the body of the car to complete the circuit.

Could my unlock wire possibly not be brown with a red stripe?

Thanks again! This is baffling me.

You are looking for a ground signal, so the other probe would be connected to a 12V + (POSITIVE) source, not the body (which is ground).

Ok! Just back in from the outside - I've figured it out. My first mistake - I had 2 brown with red stripe wires. At least, that's what it looks like to me. Apparently, when I discovered the second brown with red stripe wire and cut it, I heard an unlocking sound. Bingo! Seems I found the right wire.

I played around for a bit with that and could get nothing to work.

I eventually discovered that connecting only one end (the side with the charge) of this new brown/red stripe wire to the unlock wire from the module did it finally work!

I've tried many times splicing the unlock wire to the brown/red stripe wire and it does not work.

Question is - I've now cut the brown/red stripe wire and one side is no longer connected to anything - Does this matter?
