Bad news Tom, unless a PO has done it, the only connection you will find is a flat wire (trailer) connector for your mast lights) everything else is in the bilge. Your VHF, TV (if you have one), and wind instrument all connect in the bilge) The wind goes to a standard little black box with a terminal strip in it. On my boat the two coax cables were actually attached with wire nuts. (I replaced both with approved connectors and VHF range improved greatly as did my TV reception. Problem is I had to remove them to pull the mast this winter. Be prepared to pull a fish (tag) line when you pull the cables, and it’s a tight fit going up. I am thinking of adding connections at the base of the mast so that this becomes a quick disconnect, but don’t plan to pull my mast again for a number of years, and not sure if I want the connectors out of sight, out of mind that long. The bilge may not be the best place for them, but at least you can service them without pulling the mast if an issue comes up.
As for the rigging, mine is a 2001 and new to me this past summer. I brought the mast down this fall for inspection and to check the rigging. In fresh water with short sailing seasons like I have in Wisconsin they say 10 years is a good life. Shorter in salt water, longer seasons and how you sail the boat (stretch the rigging). Start with a good inspection full length of the wire, check for snags (meat hooks), and check each fitting for any sign of corrosion or cracking at the swage fitting. I found some cracks and that was enough for me to make replacements on my rigging. It is costing me more but I am also using the replaceable fittings rather than having them swaged on this time.
Hope this helps
