Question
could you tell me if a nissan sunny chic 1994,is a negative or postive ground.thanks

Answer
Negative ground, they have not used positive ground systems since the 1960's to the best of my knowledge.
Positive ground cars always have a sticker identifying the car as positive ground car on the radiator support or the firewall.
