Yes, Those are factory original connectors. Although they sure look like FD3S?? It is a better set up because you are grounding battery, chassis and motor with one wire. Better than just the two on the motor that are stock.
Just make sure both they and mount points are clean.
Use some electrical paste to help to keep corrosion from forming. I've been using Wurth CU 800 for years.
To test for cranking voltage just hook you meter up to the battery and watch it while you turn the key.
