Is there a major difference between the wiring harness of early 240Z's versus say a later Carburated model??? I happen to have a spare wiring harness that is newer than the one in my '70 240Z but I have no clue if I'll be able to use it with this car or not. The spare is out of a '73 I believe.

Thanks for your replies-

Several of the things that plug into the harness are different, meaning that many of the plugs will not be correct, and the locations will have changed-also the '73 harness will have several connectors that a '70 has no use for.

You are better of to either find one for your year(verify part number on the existing harness first and foremost) or restoring your existing harness.

hls30 is correct. Some of the different electrical things that come to mind is the '73 has intermittant wipers, a lighted heater console and electric fuel pump.

I've been there on this one. A '73 harness is considerably different than any of the '70 harnesses. Of which there were several variations, I should add.

After all my research, I'd say that if you need to replace the wiring in a '70 and want to use as many of the original electrical components as possible, you want to use no later than a '71, say 8/71 build date. And you'll want the entire harness, all three of the main pieces. If you use one later than 1/71 build date, you'll need the matching short pigtail fusebox to go with it.

And if you are considering selling that -73 harness, then PM me.
