Default Under Dash Wiring Mystery

Greetings everyone!
So, I just recently finished my 16 month long complete rebuild/restoration of the 69 GTO that I picked up back in Jan of 2025. Now, just a couple little things to get straightened out after her shakedown.
No kickdown happening on the TH400. FYI, new sound deadening mat and new carpeting along with new carpeted floor mats. First thing I noticed was the carpeted mat preventing pedal from going to the floor, so I cut it to clear the pedal. I replaced the switch and I have power going into it and power coming out when depressed. No power at trans. I dis-connected the wire/boot off the trans and ran a hot jumper to the terminal and it clicks fine, so I know there's a break in the wire somewhere between the switch & the trans. When looking under the dash, the plug going into the switch has a green & a pink wire. These wires go a loom with another pink wire, a black wire, a couple orange wires in it. One of the orange wires has been cut and is not connected to anything. Anybody have an idea where this should go? I have the large laminated wiring layout that I bought for the car, but it is no help.
Thank You All!
