PROBLEM TO BE SOLVED: To determine electrical connections easily without referring to circuit diagrams by identifying electrical circuits via electrical connectors having thereon a first indicia including a first indicium corresponding to an electrical system, a second indicium corresponding to a first electrical device and a third indicium corresponding to a second electrical device. SOLUTION: An electrical connector 34 having an identification code also has indicia identifying the electrical devices coupled thereby. In a first indicia 63 on the electrical connector 34, for example, the first alphanumeric character 'J' corresponds to a particular electrical system including the electrical connector 34, the second and third alphanumeric characters '4' and '3' correspond to electrical devices connected to the respective ends of the electrical connector 34, and the fourth alphanumeric character '0' corresponds to the function of discrimination from other electrical devices otherwise having like indicia. Another indicia 'T212' identifies a connection junction or a terminal strip number of one or more connection junctions interposed between the electrical devices.
