I bought a gauge from a friend of mine and i dont believe i have it installed correctly because its not reading the oil pressure correctly this is the unit it self

Google Image Result for http://www.steedatruck.com/products/ima ... 18_550.jpg

and this is the sending unit Google Image Result for http://static.summitracing.com/global/i ... 75_w_s.jpg

connect the gauge ground to a chassis ground.. or some metal surface.. the sending unit doensnt need a ground as it is grounded through the engine block.. i believe... correct me if im wrong

IIRC the positive should connect to the gauge. Then the "S" out from the gauge goes to the sender. The sender gives the gauge windings a variable ground path to change the magnetic field, that moves the needle.

There are more than pics on Summit's site. You can usually find instructions, etc there too.

EDIT: ^^^or that. Was getting there, lol

What connections do you have on the back of the gauge and what's connected to them?
