M52TU/M54/S54/S62 Wiring Loom Adapter (E30/E34/E36/Z3)


This wiring harness adapter was developed to allow the installation/swap of an E46 or E39 engine into an E36, E30, E34 or Z3 chassis.

The adapter loom is very easy to install. You only need to connect some plugs, power supply (+12 V) and ground. Instructions included – ECU simplification such as ABS and EWS removal will be required. Contact us as we can help with this, too.

This adapter loom was developed and tested to the following engines:

–       M52TUB20/25/28 with DME/ECU MS42 from E39 or E46

–       M54B22/25/30 with DME/ECU MS43 from E39 or E46

–       S54B32 with DME/ECU MSS54 from E46 M3

–       M62TUB or S62 from E39

This harness adapter will not work at M54 engine with MS45 DME/ECU
