I have searched high and low on this transmission for the plug for the two. Did some auto trans come w/o NSS and if so where is the back up light connection?
Thanks!

You need a NSS to have the back up light switch yours dont have one. So you need to get one and install it on the shoft linkage in your second pic

Thats the brake warning switch connector it goes on the H block or proportioning valve depending on what year of bronco you have. basically 76-77 have a prop valve all others a H block

I believe that's the brake light warning pigtail,(my guess) goes on the H-block or proportioning valve, located on the frame, below the brake master.
The NSS looks like this. It goes over the shift rod and bolts to the trans. like broncnaz said.
