Added oil pressure gauge no idiot light doesn’t work.

Well I finally got back to check it out. Checked all connections and made sure all the connections were good and found no issues on the sensor or any of the grounding on the pipes. Checked the bulb since I installed it new when I pulled the dash last and saw the light flicker when I went to pull it. That’s right... the connection on the twist connected was gummed up. Cleaned up and re tightened... all better. Of course that is after I tested everything else. Thanks for all the updates and help!
