I am trying to identify this connector. Looked on Shoebox's website and can't seem to find it anywhere.

It's the white connector hanging with black/white and brown wires circled yellow in the photo below

 

mine not hooked to anything dont know what it is

 

Several years ago GM went to a "single wire harness system". No matter which model you buy or options you get, all the main wiring connection are there. If you don't have an option "they" just leave the connector hanging.
The automatic has a trans. lock out on the brake pedal so you can't shift into drive until you've put your foot on the brake, it's not used on the stick.

 

Z28SORR,

Thanks for the confirmation. I thought I might have forgotten to plug something back in when installing the new motor.
