A wiring-harness includes an electrical-connector and a staging-device. The staging-device has a cavity defining a flexible-member in compressive contact with the electrical-connector. The flexible-member is configured to removably retain the electrical-connector within the cavity. The cavity locates the electrical-connector in a predetermined-position within the staging-device, such that the electrical-connector is presented to an assembler in the predetermined-position. The staging-device is particularly useful in automated, i.e. robotic, installation of the wiring-harness.
