What is in the B57 Defender wiring and ecu kit?
The B57 Defender wiring and ecu kit includes: B57D30 patch loom for the Defender 110 L663; ECU bridge connector; Immobiliser bypass or coded ECU; Sensor pinout sheet; Fuse and relay map.
It is made for the Defender 110 L663, Defender 90 L663 and Defender 130 L663 (2020–2026), and replaces the D250, D300 and P400. Gearbox set-ups we support are the ZF 8HP76.
This kit costs about 500 € to 820 €, depending on the exact listing. The engine is not included, so you can use your own B57D30 or buy one from our yard.
Shipping is a flat 249 € per order. It is added once at checkout and printed on the invoice, so there is no extra fee later. If you are not sure which kit you need, tell us your vehicle, its year and its current engine and gearbox. We help for free.
