I have A 2001 honda civic ex. Im attempting To install A water temp. guage and A oil pressure guage. The Oil Pressure guage is mechanical and i cant seem to find the Where It connets to the block. My Temp guage Neither ? I Bought the iquus guages from oriellys.

 

I think you would have to remove OE oil pressure switch and install "T" there to supply pressure to OE switch and the new gauge you are installing. The store you bought the gauges from, don't they have "Tech Support"?

I have not done the work so this is from my head. Let experts come in on this so they can point you in right direction.

 

If you got it from oreilly's then it's probably universal so yes, you probably have to buy more parts to make it work, google is your friend

 

alright thanks yeah i got the temp guage right. And The Guy Up THere told me a little bit about the oil guage.
