Description

The BMW E30 M50/S50/M52/S52 Engine Wiring Swap Harness is a complete Plug-and-Play solution designed for engine conversions into the E30 chassis. This wiring harness is modified to ensure a simple installation, comes fully labeled, and has undergone continuity testing on every wire.

Instruction sheets are included with the harness. The available cores are for manual transmissions only, with automatic transmission components removed. If sending in your original core for modification, you can specify if automatic components should be removed. This harness is compatible with E36, E34, Z3, and E39 engine harnesses.
