So question on this, how does the fuel, oil pressure, and volt gauge work on this? My ECU is the MS2PNP unit that was drop in on the mustang so I didn't do any of the soldering.

Voltage is already an option in MS to be added as a gauge

Fuel Level and Oil Pressure will need to be added to your MS2PNP. The MS2PNP has (2) open inputs still available, and would need to be wired to your options port on your MS.

Fuel Level you will need to wire in a 240ohm resistor to give enough resolution on the guage. I can provide a wiring diagram for this as well, since Steve (@a91what) helped with this as well.

Oil Pressure you will need to purchase a 100 psi transducer, which typically includes a 3-wire pigtail. On my car I wired it to the stock MAP/BAP sensor, and then took the signal wire to the MS2PNP.

If you need more help on this please let me know.

Both inputs will be taken in through the options port, oil pressure to the knock input and fuel level to the external map pin. The fuel level requires a 5v pullup, this is supplied in the kit. The oil pressure can be achieved with a 3 wire transducer wired into the baro plug on the firewall with the wiring extended down to the sensor location. The baro wire will then need to be jumped over to the options port as it is not tied in to the ms2pnp. The case on the pnp will need to be opened and a few jumpers moved, the external map will also need a long jumper that we can provide in the kit.
These instructions will be provided as well. I can even try and get pictures.
