how do you install gauges in a car with idoit lights?

i want to install temp gauge oil pressure gauge in my car and it has idiot lights any tips would help. I bought a very cheap daily driver 88 chevy celebity (cheap on gas). 2.5 4 clynder

Most electrical gauges, like temp and oil pressure have 3 terminals on the back.
One is a positive terminal that you key hot ( only has current when the key is on) the second one is a ground, that you run to a chassis ground. And the remaining one is "S" for sender. That wire goes to either an oil pressure sender that you screw into an appropriate oil galley in the block, or if it is the water temp gauge, you install a temp sender in the engine coolant chamber somewhere. You will want to get matched senders and gauges, as the resistance varies from brand to brand.

cowboyjarman I don't guess I'm understanding your question. Are you wanting to make it look factory in the gauge cluster ? or wondering if you can just put them under the dash in a separate bezel plate ? OR are you asking about how to hook them up under the hood ?

just trying to understand what your looking for?
