So an 16 sensor in the 16 engine, an 05 external portion of the sensor and 05 harness, and an 05 ECU is the current hardware situation right?
If that's the case, the internal portion is also different, a simple swap of the external sensor portion of the GPS system will not work. You'll need to swap out the internal portion as well.
Alternatively, you could install a GIPRO to trick the ECU into assuming it's in 3/4/5 all the time. This will at least keep it driving in the good ignition tables.

Problems with gipro and gear position sensor
Thanks ALL for your input.! I may have stumbled upon a fix but I won't know til I try it out. After a closer examination of my 05 gear position shaft, I noticed that there is a tiny spring recessed in the hole. I'm guessing that this spring is what makes contact with the contact pods in the original 05 GPS. With the 16, the GPS sensor has a protrusion rod that fits into this hole. Going to pull the GPS and install the spring into the shaft hole and see what happens.
