Sure thing, let’s keep this neat. First, map every wire in a simple graph—use red for power, blue for ground, green for signal, yellow for the “mysterious” data bus. Give each relay a nickname like “Pumpkin” for the starter relay, so you can refer to it without pulling up a whole list. Then, when you trim the dashboard, drop any non‑essential connectors; a single “ghost” wire is fine, just hide it in the panel. Keep the actual wire mesh under 1k verts by grouping runs into bundles—think of each bundle as a single vertex in your model. Finally, test with a multimeter before you commit; diagnostics tend to lie when I’m too sure of my gut. And don’t forget, that coffee of mine is probably in the fuse box—good luck!
