Yes we cut one wire, the signal wire from the upstream O2 sensor. The cut wire has two ends now. The end leading to the O2 gets connected to the O2 from simulator. The other end that leads to the DME gets connected to the DME wire from the simulator. We are only patching the simulator into one wire of the O2 sensor (the signal wire). When the SIM is off it connects the cut wire so the O2 operates normally like the wire was never cut. When the SIM turns on it disconnects the O2 and sends a false signal (200mv) to the DME to fool it into thinking the SAP is working. Call me at home if not clear, it is so much easier to explain over the phone, I don't mind calls at all. Best John S
