Default 4L60E neutral safety switch

2005 4L60E with the one connector neutral safety/range selector switch. Trying to get the 411 on how to get the only start in park and neutral and the reverse lights to function through the switch. I know it has to do with pins 9-12 but have no idea how they should be wired. Anyone have a wiring diagram or write-up they care to share? Car is a 67 Nova with stock column shift FWIW. TIA Darrin

I'll be going through this also, there is so much info on the older style nss switch with two plugs, but not a whole lot on the newer single plug switch. ......

Back up lights - pink wire pin11 is ignition power.
Gray wire pin 10 goes to the lights.

Neutral safety switch - pink wire pin 12 hooks to wire coming from ignition switch.
dark green wire pin 1 goes to the starter relay 85 then 86 will go to ground. 30 will be battery power, and 87 goes to the starter solenoid.

Does anyone know if the single plug is the same on the 60 & 80E? I have a 06 80E and was wondering that as well, and/or if it could just be changed to the 2 connector nss's.
