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).
