How do you check the codes on the computer on a 92 929?
 

My 92 929 is slowly and gradually falling apart , My check engine light comes on in the middle of my 1 hour trip to and from work every day I know there is a way to jumper the tester plug in and i know it's an OBD connector for the tester but i don't know where the tester connector is on that car. Also my interior lights came on yesterday and nothing i do short of pulling the fuse works to shut them off again. i tried testing all the door switches but they all seem to work as they should however the lights stil stay on. i think there is a short some where but i am not sure where to start on these either. can someone offer help???? it would be greatly appreciated.
