It goes where the light's sender is now. The light's sender goes in a hole in the front side of the oil filter block that now has a plug in it.
You need to run wire to the gauge, you can get everything else from the other gauges (power, ground, power for the light).
Look at the wiring diagram for an early car and you can figure out which wire is which. They are online at:

Here's a great instructional by Mike Bouse from the Michigan FLU page

You can also get the part that bolts onto the motor from a model that has the oil pressure gauge in it. Then you will have the both senders one for the light and one for the gauge. I did that on my old 73 124 special. I installed the Spider gauges in it. Looked pretty cool for a little ol 4 door sedan back then!
