First photo.

The T combo.
One of the two sensors is a pressure transducer which is used for oil pressure gauge while the other is an oil pressure switch which is used for idiot light. Take a close look at both - look for GM part numbers. The temp sensor on the right should be screwed into the driver side cylinder head. Remove car sensor and replace with truck version. IMHO, now is the time to get replacement sender as old ones can develop a leak.

Combo bracket - this bracket was mounted on a passenger side fender skirt (B- Body) and is used to support ESC module, ?, couple AC circuit relays and ECM fuse holder. Electronic spark control (ESC) module is used in conjunction with knock sensor (KS) to provides a voltage signal to ECM when engine knock is detected. ESC module is analog signal conditioner - filter. Depending on severity of detected knock it will pulse 9 volt output to ECM, indicating presence and persistence of engine knock.
