Yes, the pin numbers you listed are correct. I don't remember what mine was, but looking at the pigtail you bought I would say Black- grnd, Red- 5V and Yellow is your signal. There's no documentation or markings on the transducer?I actually have one of those EGR delete plugs in mine also. Do you remember which wires colors connect from the pigtail to the stock wiring?
Looking at your diagram it looks like wires 27,46,26. Would 27 be the signal, 46 ground and 26 5v?
