Siemens MS42 / MS43 / MS45 / MSS54 DME (ECU) Connector Kit

The Siemens MS42 / MS43 / MS45 / MSS54 DME (ECU) are all unique with their own software and hardware but utilize the same case and PCB header. The pinout of the different DME versions will vary but they all use the same connectors and pins. These DMEs were found in various BMW chassis from E39, E46, E60, E53, Z3 and Z4; with M52TU, M54 and S54 engines. This connector kit will allow you to build out an entire new wire harness for any version of this DME.

The S54 may be the most popular engine swap and reason to use this kit, but the M54B30 still offers great performance at a much cheaper price, especially with the amount of open knowledge around the MS43 DME. Be sure to check out the MS4X Wiki.
