The oil pressure is next to the distributor, the gauge temp is in the driver's side head and the coolant temp for the computer is in the intake near the thermostat.

Thanks.
Is the top one the temp gauge?

Is the right one for the oil pressure?

I dont need the other ones due to conversion to carbed engine.

In the top photo:
The top sensor is a knock sensor
The bottom sensor is a coolant temp sensor

In the bottom photo:
The sensor on the left is the oil sensor/switch
The sensor on the right is a knock sensor

The computer will not work the way it was designed without the sensors.
If you 1994 has an automatic transmission, it is shifted by the computer, and you will need sensors like the TPS and MAP.

We need to how the specifics of all the equipment you are switching over to, and what the truck has, to be able to give more exact advice.

Thanks Chevytech. I am putting in a carburated 5.7 liter and a turbo 400. I plan on rolling up all the excess wires and just use the oil,temp,alt, and fuel pressure regulator to keep the intank fuel pump.
