1970 wire harness

Refreshing my 1970 240Z and replacing the engine wire harness, it has seen better days. I have a nice one from a 1971, the part number supercedes by one from mine.

The only difference that I see is that 2 main power connectors, one that plugs into the dash harness, the other into the body harness, have spade connectors on the '70 harness, while the '71 has a plug connector. I am assuming that if I simply change the connector, everything will work fine.

Have any of you been here, done that?

Thanks all.
