How do I run wires from the helm to the bow for the navigation lights? The wires are held in place with plastic cable clamps running along the starboard underdeck. I cannot reach to feed thru each cable clamp. Any ideas? Thanks
 
I have taken the cable tie mounting squares with the adhesive back, pull the paper off and put a dab of 4200 or 5200 and stick up there. When cured you can reach up and install wires and cable tie. Also a good ides to clean the fiberglass off with lacquer thinner first - nothing sticks to the resin film. I also install the wire tie and sometimes connect it but with a big loop - pull tight after you snake wire. I don't usually cut the tag ends off.

It depends on how involved you want to get. You might consider leaving the old wires in place and zip tieing the new ones to the old ones.

I second Dennis's recommendation.
 
Is the problem that the plastic cable clamps are too tight, or just that you can’t reach them?
If it was a question of reach, and I really needed a new wire, I would try to butt splice the new to the old, with a really good connection and then heat shrink and lube it. Pull the new wire in by pulling the old wire out. If the old wire pulls easily, I might try pulling both new wires with one old wire, in case I lost the connection, I would still have one more wire for a second chance.
 
Yes that is the problem the cable clamps are too tight. I can’t reach the wires and also too tight to pull thru.
