If this is an MT car, go out and look at where the wire for the oil 
pressure sender breaks out of the wiring harness. On later cars there 
is a red wire that was just used on AT cars and was cut off at the 
factory if the car ended up with a MT.

If you find the end of that wire in the engine compartment, the other 
end is under the dash and may be dangling or connected to the fuel 
pump relay. Either way, it's already there and not being used. Feel 
free to repurpose it.

If this is an AT car, or an earlier MT car, you'll just have to 
install another wire parallel to the main wiring harness. This varies 
a lot, depending on the year. It can be quite difficult, especially 
on earlier cars.
