Service manuals are your friends.
On the S13 subharness the Green/Blue and Green/White wires run to the reverse switch.
On the S14 plug, the Green and Green/White wires are the ones needed.
In both instances, the Green/White wire is what runs to the reverse lights, and the other wire (green or green/blue) are power supply wires to the switch.
This is assuming, of course, that you're putting this in a manual car. Autos require different procedures
