Wiring diagrams

This wiring documentation is for Burnt Toast, a 2008 Lagoon 420. Without any wiring diagrams from the manufacturer, we have drawn these ourselves as projects required them and have done our best to keep them accurate. Drawings are made using draw.io, updated and stored by Doug. Downloadable PDFs are below; filenames use an ISO date (YYYY-MM-DD) so you can match each file to the revision shown.
