What do you mean by "i have a wire from fuse box that states it goes to 49a"? What "states" where the wire comes from/goes to? In the Haynes manual and the diagram above, the wire from stalk terminal 49A goes to the flasher relay terminal 49A. Are you sure your wire goes to the fuse box? What colour is the wire?

As I said above, the diagrams are based on my car. If you're using a sierra loom, let me know and I'll tell you what the standard fuse numbers are.
