Hello, I have decided to add spreader lights to my S299 and am uncertain how to run the wiring down the mast? Presently there is the all round light, streamer light and a radio antenna on the mast top. There is a 3 or 4 wire plug that has been installed at the base of the mast and sealed up with some white sealant. My question is how do I get the wiring down the mast and where should I drill through to locate the spreader light wirin? There is a couple of aluminum fittingd that hold the spreaders in place. Thanks, Peter
