What is in the B58 BMW wiring and ecu kit?

The B58 BMW wiring and ecu kit includes: B58B30 patch loom for the BMW E46; ECU bridge connector; Immobiliser bypass or coded ECU; Sensor pinout sheet; Fuse and relay map.

It is made for the BMW E46, BMW E36 and BMW E90 (1998–2013), and replaces the M54, N52 and N55. Gearbox set-ups we support are the ZF 8HP and ZF GS6-53.

This kit costs about 500 € to 820 €, depending on the exact listing. The engine is not included, so you can use your own B58B30 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.
