Race German Plug-and-Play Engine Harness Extension Kit

Note: Kits are made to order and can take 5-7 days.

Simplify your BMW engine swap with the Race German Plug-and-Play Engine Harness Extension Kit. Designed specifically for use with E46 engine harnesses, this extension allows you to relocate the engine harness to the factory DME (ECU) location without cutting, splicing, or permanently modifying your original wiring.

Many engine swaps traditionally use Z3, Z3 M, or E39 engine harnesses because their longer length makes routing to the factory DME compartment easier on left-hand-drive vehicles. This extension kit eliminates the need to source a different harness by allowing your existing E46 harness to reach the original DME location with a true plug-and-play installation.

Each harness is professionally assembled and continuity tested on every wire to ensure reliable electrical performance and OE-quality operation.
