Rally dash oil pressure gauge issue.

One thing I havent mentioned, I do not have the bulkhead connector that runs to the wiper motor and trans revers switch connected. Also the headlights and tail lights arent wired up. I dont know if this has anything to do with it, but I have thought that I should wire every thing up and see what I got going on. It seems like everything worked before in fact the car always amazed me because it didnt have any or many electrical issues. I have owned other Mopars where the wiring issues at the dash were atrocious. hat pulsing brake light kinda had me a little tense last night i was like "now WTF...":)
No, That 3rd connector in the bulkhead was called wiper connector for several years, only because there were no other wires/circuits in it. When the reverse lamp switch moved from inside the cabin to at the trans' the factory took advantage of previously unused ports of that connector.
Anyway... It shouldn't have any effect on gauge operation.
