Did it
I step and unstep the mast on my 1980 Hunter 30 Tall Rig almost every year. About ten years ago, I installed spreader lights.On my boat there is one wire containing 4 leads for the steaming light and the anchor light. There is a connector plug which you disconnect, once the mast is lifted 4-6 inches above the mast step. There should be a quick connect, which can also be detached once the mast is unstepped.To install your wires for the new equipment in the mast, you need to slide out the mainsail sail track. It pulls out from the bottom of the mast. Behind that is a channel in which you can run some wires. It is not a very big channel, so try to bundle everything neatly or you will never be able to slide the sail track back in.Wrapping all wires in a bundle with tape is a good idea to eliminate chafe, vibration, or clanging.I would put a quick connect on any new wires that you put in so that you can unstep the mast in the future and reattach without having to crimp while the mast is hanging in the air. I use black tape to ensure that the connectors will not open and a little vaseline on the terminals to fight corrosion optimize conductivity.There is very little room for the wires to be packed back in between the bottom of the mast and the mast step, so wires have to be kept relatively short, and connectors should be as small as possible, packed into the mast step neatly when you re-step the mast. The mast is hanging in the air when you go to reconnect everything, so have everything ready, try to match the lengths of the wire coming out of the step and on the other side coming out of the mast, to the length of the existing wire, longer will have you scrambling to cut them down and reattach connectors, with the mast dangling from a crane. WATCH YOUR FINGERS when you restep the mast.Of course, while the mast is unstepped, its a good opportunity to change the steaming and anchor light bulbs. I also installed a Windex wind indicator as a backup to my electonics.Hope this is of some help.
