Default Oil Pressure Gauge

I just dropped a used engine into my poor bonneville. My oil pressure is not reading right it reads full preassure The engine i put in was from a 1989 Oldsmobile 98' are the sensors different? Anyone ever heard of this happening.

My radio is also locked out and i have to use my mute button on my steering wheel controls to unlock it but the controls dont work anyone know of a way to bypass this problem?

It might be the sensor, then again it may be the wiring in the cluster. My gage read somwhat high when the weather is cold but never full pressure.

Electronics and gages are such a PITA when cars age

Default Gotta be the sensor

I dont believe its the wiring cluster because i used the one from my old engine and it worked fine before changing engines. I'm gonna try changing the sensor hope that gets it working.
