Trailer harness not working - turn signals

Hey gang,

So I got the trailer wiring harness activated a couple days ago at the dealer. Mine is 2011 GC Laredo X. Tested it with a test light that plugs into the 7 blade socket and the turn signals don't work. Everything else works - lights, brake, backup, power but not the turns. I checked the wiring and the connections since I spliced in a new adapter and everything checks out. So assuming everything at the back end is good, any ideas as to what it could be? Are there separate fuses for the trailer turn signals? I have a brake controller hooked up. Although I wasn't actually hooked up to the trailer, but just using a testing light.

a little more info since it might be confusing. The pictures are showing where I spliced in a new 7 blade adapter/connecter because the factory one was all corroded. All of the splices are securely crimped and heat shrinked. I tested all of the wires before and after the splice and all are good, and I made sure I transferred the wires correctly from one to the other even though a couple of the wire colors are different.

I think the stop and turn signals are on the same wire, if the stop lamps work so should the turn.
