Jim, if by alternative light connector kit you are referring to the upgrade from the original RV-12 wing electrical connector ? the page in the RV-12 plans that show the new connectors and wing rib attachment is 16-04 Rev1.
The part numbers for the new blue floating connectors are ES-00077 (female) and ES-00078 (male) and they attach onto the wing?s inboard nose rib using two standoffs part number ES-00081 (two per connector). The screws are MS35206-215 (two per connector) and washer NAS1149FN416P (two per connector).
The floating connector pins are all the same ? part number ES-00079 (16-12 AWG) one per each wire to be connected onto each of the connectors.
Hope this helps you.
Happy building,
