Sure
The wiring colors and pin positions are the same for early and later turn signal switches. The old style has a half-round connector and the new style is flat. New replacement switches come with the flat to half-round adapter.
You can also splice in the pigtail end that I'm including. That updates your truck harness to the flat style connector.
I think you can buy the flat to round adapter separately.

The neutral/reverse switch wiring is similar. Splice it in as necessary. If you have an auto column already you can just swap the connector since it is slightly different. If it's a manual then you can use the pigtail to wire them in.
