Oh I see, I thought you were looking for the wires as they came out of the fuse block and to the respective flashers and such.
Are you sure that you're not getting power to the flasher? Check the grounds in the front turn signal sockets. Both of mine were bad when I bought the Jeep and the signals didn't work. Repaired te grounds and they've worked fine for years.
Anyway, the easiest thing to do is going to be just pull the fuse block, it's two screws, you can pull it and it will pull out about 6 inches. Enough to turn it around and gain acces to the fuse socket in question. If yours is anything like both o mine were you're goin to find a nasty mess behind the fuse block. I had success removing the terminals from the fuse block, cutting the wires back and replacing the terminals with spade connectors. You can stick it back into the fuse block and its good as new.
