Heres a pinout diagram I found for a 944 S. I think the pinouts that djnolan referenced are correct for a N/A but different for a 944S. I think pin 1 and pin 2 are the equivalent to pin 1 and 5 on an NA (could also be pin 8?). That said, the advice remains the same. Check for signal coming from pin 2 and from pin 1. I assume if a signal comes in through 2, it should go out through 1. Im not sure if you need an oscilliscope or if a simple test light would work. I think the best way would be to back probe the pins
