1991 Thunderbird SC low oil pressure/low temp readings

I have a 91 SC with low oil pressure reading and low temp reading. Have replaced both sending units but problem persists. I have checked the oil pressure with external gauge and it's fine. Same with temp, checked with infra red gun and reads about 190 deg at the base of sending unit. Engine runs fine with no issues or noise. Fuel gauge reads full no matter what. Cluster malfunctioning?

It was the circutboard to the right of the cluster that was not entirely in place and the wire from the oil pressure sending unit that was faulty. Replaced it with a new wire and everyting works fine.
