This adapter is intended for use to replace ageing MBE ECUs in the Nobel M12 and M400 cars.
This maintains all the OEM functionality, including the water temperature gauge on the later cars.
NOTE: The factory wiring harness is slightly different between 975B ECU and 975D ECU equipped cars. B cars need an additional wire adding in to enable this adaptor to work.
