24V starter control relay cross-referenced under Isuzu 8980056311 and Nikko 0-25000-9061. Isuzu engine parts catalogs document the relay in 4HK1, 4JJ1 and 6HK1 electrical-control systems. Five exact owned photographs show the same relay, bracket, connectors and nameplate. This is a control relay, not a starter motor or starter-mounted solenoid.
