Thanks everyone,
i did some more digging around because my instructions said to connect the 2 terminals to the same thing lol.. or i just read it wrong.
Anyways, i grounded 1 terminal and the other went to the sensor wire on my gauge. All running good now
Last question, what is normal operating pressure? My gauge is digital reading in PSI. When i put my foot down whilst the car isn't in gear, it shoots to about 89 PSI, whilst on the stock oil pressure gauge in the dash, it only hits up to 5 which is converted to about 71 PSI.
When in idle, it's reading around 26-27 PSI. It's a few psi different from what it reads on the stock gauge, but i've also heard the stock one isn't too accurate.
