I can't figure out how to install the oil pressure gauge, Not sure what type it is all it says on the gauge is JDM and its like a glow light gauge, it's got one red wire, one black wire, and one green wire. I got the red and black wire hooked up but with the green i tried hooking it up to the oil pressure sensor on the back of the block next to the oil filter and the gauge doesn't read anything. How do i hook it up?

 

did it come with directions? if not you can T into the oil pressure sensor then run your wire off of that

 

it's a electronic oil pressure gauge, and i bought the car with the oil pressure gauge in it but not installed. Was the oil pressure gauge suppose to come with its own sensor or can i just run it off the stock oil pressure gauge?

 

if thats the stock sensor it's for the idiot light and won't run a pressure gauge you need a sending unit for that gauge.
