Plan

Battery-to-Lynx wiring schematic with the routing notes (keep away from exhaust and heat).

The plan

Follow the diagram, not a forum thread.

Every kit ships with a detailed wiring sheet: each wire labeled with size and length, each fuse rated, each terminal named, and an install order that matches. That is what keeps the phone quiet.

What you see here is the overview. The sheet in the box adds the wire schedule, fuse ratings, notes and code references.

Questions

Before you order

Why is the input cable so long?

The charger lives next to your house batteries; the other end goes to the vehicle battery. The wire is sized so the charger still sees enough voltage.

Can I route it near the exhaust?

Avoid it. If a section must pass heat, use a shield and high-temperature wire. The Wire & Sun calculator flags hot routes.
