I have a block out of an '80 280zx, but it's in a '77 280z. I need to get a new oil pressure sending switch, but I don't know if I should get one for the '80 or '77 because I'm not sure if they were wired differently in '80. I would assume they use the same fitting for the block, though. Anyways, the question is what year should I buy the sending unit for, '80 or '77? Thanks
My '77 mfg date is 12/76 and has a single round terminal . Went with the general advice on this item and went to Nissan. He ordered a couple different #s. I got the Nissan #25070-89972 and I works well although a little pricey(about $65)...even has a nice rubber boot! Of course a mechanical guage is always the most accurate but can have potential problems also. Good luck!
