Typically you have to buy the senders separately.

On an Olds engine, the oil pressure sender goes in the small, 1/8" NPT port on the timing shelf behind the water pump. It's located on the drivers side of the engine, opposite of the oil fill tube.

The water temp sender will go in one of the NPT ports in the intake next to the thermostat housing. Depending on what size NPT thread your temp sender is, you may have to also run an adapter bushing.

As far as how to wire them up, most guages are setup the same way. You'll have a terminal on the back of the gauge for the sender wire, one for a switched 12v source, one for ground and another for the lights. You'll need to run a wire from the sender to the gauge if you really wanted to, you could just tap into the original sender wire under the dash instead of trying to find a way to pass a new wire through the firewall.
