autometer oil pressure gauge... sending unit?? where does it go?

[Formula Z]

sorry guys but another one for you. i purchased two auto meter gauges, one trans temp gauge which is basic and then an oil pressure gauge. where does the sending unit mount? am i going to have to buy more pieces to make it work with the ls1? want to get the wiring or running of lines figured out before the engine goes back in. thanks
