oil pressure guage install question

[farmer]

well as some of you know ive installed an rb26 into my litle 240sx, ive got the motor running and now im in the stage of hooking up aftermarket guages, i was goin to ask about doin the boost and oil pressure but i just saw the post on the boost guage and i figured that one out

So i guess i need help hooking up the oil pressure guage, if anybody has hooked one up to thier car and would like to share thier knowledge it would be greatly appreciated

thanks in advance
