Most of the gauges are wired directly to sensors and not through the PCM, so there is no problem.. this includes oil pressure, fuel level, volts and coolant temp. The tach comes off the PCM, but it is feasible to connect another type of tach that runs off the coil. The speedo is the challange.... the only signal source is the PCM, or direct from the VSS (leaving the feed to the PCM in place also) so you need an electronic speedo, not an aftermarket mechanical unit. And you need an interface box to take the signal from your VSS sensor and translate it to the signal required by the aftermarket electronic speedo. Dakota Digital makes these interface boxes.
You will also have to incorporate the infamous SES light... if the PCM sees it is not connected.... it will set a code....
