Default Stupid question about the neutral safety switch...

ok this is dumb but...where in the harness does the wires come from for the neutral safety switch on the side of the tranny? Doing a 4L80E swap and somehow I literally lost the wires/plugs that go into the switch...like I can't find them anywhere and I can't find any pictures that show where in the harness they are or where they should be coming from. FYI this was a complete engine/tranny pull out and rebuild so all of the harness was just hanging for a while...thanks folks.

If you have a puppy like mine, she chewed them off.
It has been a while, but I think they branched out of the harness with the big round trans plug.

i haven't been able to find it there, and the wiring harness pictures I have seen don't show it either, just the tranny plug, VSS, and rear O2 sensor plugs. there must be a separate harness somewhere with these in it...

Not sure if this will help, but here's a pinout from Holley's harness for the 4L__ got this from one of TruckDoug's awesome YouTube vids.
