You'd definitely have to add a temperature sensor and an oil pressure sensor to provide output for those gauges, as the engine doesn't have either in stock form. There's no temperature sensing ability at all in the bike as it was built and the oil pressure "sensing" for the warning light is a simple switch that opens or closes at a specific amount of pressure.
A temperature sensor is relatively easy to add, as you simply need to find a good location to stick a temperature probe on the outside of the engine. Perhaps on top of the valve cover or inside the valley for the spark plug holes.
The oil pressure sensor is a little more tricky. If you're retrofitting a fully digital gauge cluster that has a programmable oil warning light, you could perhaps replace the original oil pressure light switch with a sensor that had the same threads, and program the light to only come on below the typical oil pressure at idle. That's probably the easiest way to do it.
