On your boat it should run as follows: the halyard exits the pole through the block just in front of the main beam. It runs up the front of the mast in front of the spreaders, trap wires, and side stays on either side of the forestay (I prefer the starboard side) up throught the halyard block to the top of the spinnaker.
