I can never remember the colours but try this guide for wire colours:

One wire is oil pressure light and the other is oil pressure gauge. One goes to the plug and one goes on the pin, both go straight to the clocks.

If your car didnt have an oil gauge/sender as std, you will need to run a new wire to the terminal post from the clocks.

The other will be within the std car loom and controls the oil light.
