Neutral Safety Switch Wiring

[Mooseman]

First post here. I have a 96 tahoe and I putting in a transmission and engine. I had to cut the wires going to the 7 pin connector to the Neutral Safety Switch (MLPS). I was rewiring it today and there are two green wires. I thought there was some way to differentiate them but I used a light to shed more light and pulled out my calipers to see if there was a difference in diameter which it did not. I have tried to find a schematic so I could figure out if one wire would be a supply and the other is a pass through but have turned up nothing. Any help would be appreciated. FYI the wires are about 18 awg or so.
