...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!
