If it didn't already have a wind S/D transmitter at the mast top, then there may not be wind instrument cable running up to the deck under the mast. My wind inst. cable (on 1990 Hunter 33.5) runs down the mast in a wire 'chase', comes out of the mast thru a small in the side of the mast with a rubber grommet and goes down thru the deck thru a Blue Seas Cable Clam (it has a solid rubber center insert that you drill a hole thru for a tight fit to the cable). Cable then runs down the bulkhead next to the head door and is held in place with nylon cable clamps. It then runs thru the dry bilge under the sole, goes thru the port side of the engine compartment bulkhead, up the side of that and into the overhead across to the back of the wind display unit on the forward starboard side of the cockpit. For unstepping the mast I put a plastic junction box ("Project Box") in the dry bilge opposite the head area with a "Euro" terminal strip inside. Hope some of this helps.
