Weight basis
Maker page/manual does not establish complete gross assembly or net vehicle-added weight. Cable trimming changes carried mass; weigh the finished wiring and all added hardware. Shipping mass is excluded.
Professional installation
3–5 hr · researched planning estimate
Installation scope
Researched professional wiring-task allowance3–5hours for protected front-to-rear routing, trim access, measuring/cutting, approved crimping/terminations, fuse-holder attachment and electrical checks using exact INST187-3guide. No manufacturer shop hours published. Shared with existing Alpha25 charger job: use maximum grouped allowance rather than adding wiring twice. New battery mounts/fabrication and source-system redesign extra.
Fitment / supporting work
Correct cable and fuse sizing protects a charging circuit. A universal wiring kit does not approve a particular LC250 hybrid electrical installation.

Why consider this?

Choose wiring by charger rating and measured route, not straight-line battery distance. Confirm Alpha25 architecture and have the shop quote the combined wiring/charger job.

Required equipment & checks

Planning requirements for this product. Your exact vehicle and complete build still need confirmation.
