I need help with two problems.

I need help finding the gasket for where the transmission meets the drive shaft

and where does this loose wire plug go?

 

2WD? Output shaft seal, just remove the driveshaft and replace it.

See here for a picture of connector functions:

Thanks! And yes 2Wd

 

Still unable to figure out where the plug belongs

 

I don't see any plugs missing on your transmission. Was that a 4WD converted to 2WD?

 

This is what the build sheet said.
"4-Speed Automatic AW4 Transmission"

 

Can't say for sure, but I'd guess it's for the 4WD switch/light on the transfer case. That's the only connector that would be in that area that isn't accounted for. You don't have a transfer case, but I bet the same wire harness is used either way.
