The type of connector to attach to the ECM and pin locations in the connector will depend on the engine being tested. The connector and pin locations shown are those used on the ECMs of current production 3176B and 3406E Engines. For other engines, the parts manual and electrical schematic of the engine to be tested must be referenced to determine the correct connector part number and pin location. If you use the 9X9647 Throttle Position Sensor in your dyno test setup, it will work with all electronic engines.
