Galind, yes did this a while back on my ‘84 H31 when changing my bow light to a LED version. There is an obstruction in the bow pulpit. It does not allow fishing the wire upwards along the top rail and then down. I removed the bow pulpit from the boat and tried to get new wire fished thru with string, washers and magnet along the top rail and downwards with no luck. Existing wire runs downwards and exits outside the pulpit. Will be at the boat tomorrow and will send u a photo of where we had to exit for new light wire.
