4L80e wiring help

[Liltroy]

I'm got my wait4me harness back today and I'm really confused about the wiring on my transmission.

First off, these are the only transmission connections on the harness



and this one yellow wire, mixed in with a bundle of unlabled wires. I dont know what to do with any of them....even the labeled one!!!



so that still leaves the plastic gear position thingy on the side of the trans to deal with. there are no wires in the engine harness that connect to it so what do I do about that? doesnt the ecu need to read that module to know what gear its in and things like that? I'm REALLY confused and would greatly appreciate any and all help!
