Mechanical Oil Pressure Gauge...
 

were do i go about hooking it up to on the engine?

Got the instructions from the gauge? What engine?

You usually tap in at the same spot where stock sender is.

You may be able to get it in two places... I know with the 95 blocks there is the stock oil pressure sender behind the intake and a port around the driver side motor mount where yours is stock.

Not sure if the 93 blocks had the extra port behind the intake or not. Check there or just tap off the one around the motor mount.

isn't there a plug in the side of the oil filter mount?

Why not just tee where the stock sender is?

Well he may have too.. if there are two holes like the later blocks, then he has an option of where he wants the sender, but if there is only the oil sender one by the mount, then he will have to tee it there.

its a 93 LT1

This is where the stock oil pressure sensor is on the 93. http://shbox.com/1/aux_oil_port.jpg
