97 240sx automatic with oil and airbag light on when car is off
 

just picked up a 97 240sx automatic last friday and it does a few things i am worried about.
firstly the oil light comes on when i turn off the car. it is off while driving but as soon as i park it and turn the key to the off position the light comes on. yes it has oil in it.

secondly, also while the car is turned off, when you press the brake pedal the air bag light comes on. ( it is on while driving as well from what i was told the previous owner tried to replace the steering wheel and messed up the clock spring) i am worried that these 2 issues are wiring problems and am looking for a good place to start with diagnosing them.


any help is greatly appreciated. thank you.
