An electrical junction block as used in an automobile electrical system has a pair of ports for removably receiving two separate connectors into connection with circuit traces of a printed circuit board contained within the junction block. The first port is configured to receive a wiring harness connector associated with one or more electrical devices into normal operating connection with the junction block. The second port is configured to removably receive a connector from a continuity tester such that terminals of the connector contact the circuit traces so as to be in electrical contact with the wiring harness connector. Accordingly, inserting the tester connector into the second port after the wiring harness connector is operatively installed in the first port puts the tester in connection with the electrical system via the circuit traces and allows the tester to perform a continuity check of the device without disconnecting the wiring harness connector. Further, the tester is able to check the connection between the wiring harness connector and the junction block.
