Need help with oil pressure gauge

[Deathmug]

I know this is a total n00b question, but that's why I'm posting it here.
Where do I plug in my oil pressure gauge line? I've looked all over, but I just can't seam to find a place to put it. It's a 97 Talon TSI eng.

what kind of gauge is it? Aftermarket? Is it mechanical or electric? What all came with it?

just pull off the stock unit and replace it with your own gauge if its mechanical..

i think the electrical can use the stock sensor. WRONG.
