Trailer harness problem. (MOPAR part)

Bought a brand new MOPAR trailer harness from the dealer. It was supposed to be totally plug-n'-play. The connections matched up and I DO have pwer, but......

Back up lights and parking lights on the trailer harness work well.....but no turn signals or brake lights. No power in those sockets, but they still work on the Jeep. The plug-in trailer harness flasher units are cycling properly, but no power to them at the plug in for the trailer socket. (the center two pin sockets) So,..........

- Stumped.

Anyone else? Advice?
 
Are they on a fuse? Just had this problem with a work truck, blown fuse for the trailer blinker. It was a seperate fuse from the truck's lights, so it had us stumped until I dug out the owners manual.
