Transfer case wiring

I'm trying to figure out how to wire a transfer case into my 2wd nissan titan, part of a conversion project and turning out to be the tricky part. Is there a schematic or wiring diagram out there anywhere, or has anyone found a way to wire it as a stand alone unit without tying to the factory ECU?

I was told before I would only need to purchase the TCU to control the transfer case and it is plug and play to my factory ecu, but I can't find the plug behind the glovebox where the TCU mounts from the factory...

so I'm looking for a way to wire it up without tying it to the rest of the truck I'm not worried about dash lights not working and whatnot.

Thanks
