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...":)
