360 Magnum with stock EFI engine codes

I’ve been able to do a few trips into town and around to shake down any issues with the car. I just hooked up the scanner and I have 8 codes. I expected to have some, and I’m not overly. Concerned about it, but if anyone has fixes for any of these, I’m all ears.
First background for those who haven’t seen my threads. 67 Dart, was a slant six. Now has 1999 5.9 magnum out of half ton 4x4. Trans is 42rh out of 1993 2wd half ton. Computer and harness out of the same 99 truck. Currently using toggle switches for OD and torque converter lock up. Using electric fuel pump from the 99 half ton mounted in the stock dart tank.
1. P0500 vehicle speed sensor A
2. P0753 shift solenoid A electrical
3. P0132 O2 sensor circuit high voltage bank 1 sensor 1
4. P1899 P/N switch stuck in park or in gear
5. P1492 Ambient/battery temp sens volts too high
6. P1763 governor press switch bolts too high
7. P1765 trans 12 volt supply relay ctrl circuit
8. P0138 O2 sensor circuit high voltage bank 1 sensor 2

Solo PCM's in Florida can sell you a PCM with the correct things disabled for a reasonable price. They are who I used, but I also had the ECM reflashed for more performance several times as I made upgrades from a stock motor to a stroked motor with ported Eddie heads and bigger cam. This required the purchase of a hand held tuner and a remote tuning service, which was not inexpensive. It was definitely worth it for me though, as it made a major performance difference even on the stock motor.

My ECM used 4 O2 sensors including 2 pre-cat and 2 post cat. I am using an O2 signal generator on the post cat feeds to avoid codes. I am running the pre-cat O2 sensors though, which is kind of the point of running modern EFI, the self tuning feature.
