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. Please note the following:

• In the case of E34 chassis, please tell us your original engine/model
• This harness adapter will not work with M54 engines with the MS45 DME/ECU
• If you do not see you spec in the dropdown options, please contact us or leave a note on your order when checking out

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
