7-way Wiring Problem
Hey Guys, I purchased a new TV and now the 7-wire won't reach from the TT to the TV. So, I bought a new longer 7-way and proceeded to try to re-wire everything in the junction box under the T...

From the original chord the three dark blue/blue stripe/light blue were in a scotch lock. Same as the three different greens. Two reds were together. One single yellow and two browns.
I know I messed up when I removed the scotch locks.
Yes, they were the side and front marker lights that didn't come on.
I was able to confirm (Used a wire from the positive on the batter and touched the wires. I know I am still missing something. I changed from the original message based on what they told me at CequentGroup. Apparently they make the Bargman wire. They neglected to tell me that this particular model has a different wiring scheme. I have changed it so many times now I am confusing myself more.
Who knew that some 7-wire are different from the same manufacturer? They admitted the messed up.
Thanks!
I see now that your original picture shows what was there. Since there were 3 wires in the green connector, one must be the front markers, separate from the rear ones. Do you still have both of those trailer-side wires in the same connector, regardless of the color coming from the truck? It seems from your wiring description that the truck side is using brown for the tail/marker circuit.
Since you are able to connect power from the battery to each trailer wire, just figure them all out one by one. Then, pick one (like the front markers) and then connect it one by one to each wire on the 7-way. As you do, try the various truck functions (left/right/tail) to confirm. It seems like you're close if you have those 3 working for most of the trailer, though.
The reason for 3 blue wires is probably one from the truck, one to the brakes and one from the breakaway switch.
