Posted July 20, 201212 yr comment_396261 I'm in the process of swapping my 77 280z to a 79 280zx harness/ECU. I have this plug and I'm not sure where it goes or what it's for? Any ideas and advice for the swap? Link to comment https://www.classiczcars.com/forums/topic/43863-name-that-plug/ Share on other sites More sharing options...
