Compare real wiring between your car and a donor — the exact pins to add, change or remove at the connector, with destinations, wire colours and disconnection safety. Pick any component or system from any same-generation BMW (F↔F, G↔G, E↔E). Every value from a real BMW wiring document.
Pick your chassis, then search for any component or system you want to add — from any same-generation BMW (F↔F, G↔G, E↔E). You get the real wiring delta between your car and the donor: the exact pins to add, change or remove at the connector, with destinations, wire colours and disconnection safety. Every value comes from a real BMW wiring document. No VIN required.
Load your car — optional, from SVT + FA
Drop your vehicle's SVT (system table) and FA (order) to scope the retrofit to your real configuration — chassis, build date, the factory options (SALAPA) you have, and the ECUs installed. Or skip this and search openly like today.

These are the admin-curated, evidence-grounded retrofit options for your chassis. Pick one to see the full impact report (what modules/wires/pins change).
No curated retrofit options for this series yet. An admin needs to configure the catalog in /admin/retrofit first.
Compare wiring
Search for any connector or system to open a pin-level comparison between two wiring documents (e.g. halogen vs LED on E5).
Type a component, connector code, or feature name to search.
