Not to risk crossing the 'Great Rooska', but...
...if your 28.5 is anything like mine, the wire runs within the pulpit and exits just before it meets the toe rail. This wire penetrates the non-skid nearby (you can see the exit and entrance points to the left in the attached picture).
From there, you'll need to open the forward access in the V-berth and play contortionist to follow the wires back to the panel.
It's manageable, especially if you can use the exiting wire as a messenger line to string new wire (if needed).

PS - And for those thinking it, no it wasn't me that chopped the toe rail 'beaver style' to complete the bow cleat installation!
