Comparing to OEM Starter...
The OEM starter is similar, the only real difference is that the one terminal on the solenoid closest to the starter that actually connects to the starter isn't the same design - one couldn't connect the battery cable to it if ya tried. The new starter, as you can see, uses the same type of terminal to connect the solenoid to the starter.
It's obvious now...sorry I didn't inspect it closer initially.
