1) Coolant temp
2) Oil pressure
3) Fuel
4) Speedometer
You'll need a PCM to make this happen, and the appropriate sensor inputs to the PCM i.e. coolant temp, oil pressure(has to be correct type), modified fuel sender circuit, VSS.

Ok, just trying to help here, so I'll part with this. Aftermarket PCM's most likely will not have provisions for class 2 communication, unless they are a replacement for a C5.....so you'll need a C5 PCM. With regard to F-bodies, I know that as late as 1998, the oil pressure, and coolant temperature were direct from the sensor to the instrument.
Good luck
