I have a 94 and I don't have a temp. gauge either :eek: . Maybe it was an option or standard on uplevel models? I know GM was big into optional dashboards in the 1980s and 1990s.

I think it can be programmed through the DIC but I forget how. It should be in the FSM if you have one.

hey just curious is there any way to rig up external oil, temp, volt gauge cluster or even a tach just to bolt on to the console? if so how?
i wasn't sure due to the digital dash and its wiring

Of course you can install aftermarket gauges. Remove oil pressure sending unit near the oil filter and with the proper fittings you could use a mechanical or electric oil pressure gauge. Volts is simple, just find a wire that has power with the key on and tap into that. Temp gauge same as oil pressure, remove factory sending unit and install aftermarket sending unit in it's place.

Ok,

See this thread I posted some time back to "upgrade" your 95/95 Deville digital IPC to show Coolant (engine) temp, Engine RPM's and Battery Voltage.

This isn't too difficult and it works great. I did it several months ago, and a number of other members of the forum have done this mod as well.

Basically, the IPC programming procedure adds these 3 missing parameters to your DIC display.

This will also save you the hassle of adding aftermarket gauges, unless you really want to.
