Ls with 4wd wiring

Good morning all.
My LS swap is going on a 4x4 and am trying to figure the wiring for the 4low circuit.
The exam has a 4wd circuit and a axle switch. Pins 2 and 3

I can’t seem to find the schematic for a 2008 gen4 with e38 ECM/ 4l60e transfer case wiring.

Do they just need a ground? When in 4low? Not in 4low?
Do they need to have 12+?
Do I need both? Just 1? Which 1? Etc.

I have email Brendan at lt1swap but have not heard back.
What have you guys done?

Thanks
