Aircraft electrical system

A computer program product comprising instructions which, when executed by a computing device comprising a processor and memory, causes the computing device to carry out a method of configuring an aircraft electrical system, wherein:

• the electrical system comprises a wiring harness and a plurality of electronic modules;
• the wiring harness comprises a plurality of connection points;
• a first electronic module in the plurality of electronic modules is connected to the wiring harness via a first connection point in the plurality of connection points;
• and
• the method comprises:
• transmitting by the first electronic module, a connection point identification request;
• in response to the transmitting, receiving at the first electronic module from the wiring harness, an identifier of the first connection point;
• on the basis of the received identifier, determining configuration data for the first electronic module, the configuration data being associated with the first connection point;
• and
• configuring the first electronic module to operate in accordance with the determined configuration data.
