1973 vs 1974 manual 620 wiring harness

[Jbone88 0]

I found a great wiring harness in a manual 1974 datsun 620 at pick n pull and was wondering if there would be any issues installing it into my manual 1973 datsun 620?  I took a look at both wiring diagrams and they look almost identical.  Has anyone tried this before?

I don't see why not. Usually the plastic plug ends are the big differences.
