A question about oil pressure guage wiring

[gwilson09]

I recently acquired a gauge cluster with an oil pressure gauge instead of a dummy light. My truck has an oil pressure sending unit for a light, not a gauge, so I know I have to replace my sending unit. My question is about how to wire the new gauge. There are two posts on the back of the OP gauge. What wire goes on each post? Once I get this taken care of I'll have a complete set of working gauges.

Nevermind...Found what I needed after doing a very thorough search of the forum posts.
