Not to sound dumb but connect what to what lol.
I dont think its a bad ground though because i have my battery ground run to my water temp gauge then i have a wire from the ground on my water temp gauge over to my oil pressure ground so if my ground was bad my water temp gauge would show it first.
One thing i noticed today is that when i started it up this morning it showed around 80-85 psi and stays around the 70 psi mark all the way to work (23 miles). When i get to town( about the 21 miles mark) my temp creeps up to the 190-200 range and sometimes 210 range and when that happens my oil pressure drops to 35 psi at idle and 60 psi at 3000 rpms which seemd about right. from the time i leave the house untill I get to town my car never goes over 180 degrees, then like i said around the 190 mark the oil pressure seems to be right
Is the fact that my car only gets to 180 going down the road the reason why my oil pressure doesn't drop?
I also forgot to mention the oil i used was mobil 1 high mileage full syn. 5w-30
I wonder if the high mileage oil has anything to do with it?

Just connect the red lead to the place you think is a grounding point and the black lead the the negative battery post, which is the "mother of all grounds". The reading should be 0.0V, however any resistance (bad connections mostly) in the path between the "grounding point" and the negative battery post will cause a voltage drop--the meter will read this and it will be an indication of the quality of the "grounding point".
Unless you have an after market thermostat the engine should always be around 210° once it reaches full operating temperature--that's what the thermostat does...

As a semi-retired mechanical/electronic engineer I am not sure I have any other words explaining how to perform a voltage drop test. The good news is it's easy...

I did my heater core at the same time and it honestly was more of a pain in the butt installing those gauges than putting a heatercore in, that part was really easy for some reason.
P.S I hate wiring stuff.

Here you go.
night time, with green cover. They come with a green and red bulb cover but I think a blue would match the rest of the interior much better
and day time
