I have a late 1974 260Z, and I need a dash wiring harness for it. I found a guy who has a 1975 280Z dash wiring harness.

If my memory serves me right, everything under the dash is the same? I searched the forums, and I didn't find anything on the differences yet.

Thanks for any help you can provide,

The late '74 is exactly the same. A few months later the 280z was introduced. Only diff was the bore size. Just make sure you mark both sides of each connection or you will have a possible nightmare. Change up the fuse box too with the correct size fuses. As the fuse box terminals got corroded and blew fuses the owners would put higher amp fuses and overload the system. See past related threads
