How do you install a starter in a 2006 scion?

To install a starter in a 2006 Scion, first disconnect the negative battery terminal to ensure safety. Then, remove any components obstructing access to the starter, such as the air intake or battery. Unbolt the old starter from its mount and disconnect the wiring harness, then install the new starter by reversing the process: connect the wiring, secure it with bolts, and reassemble any removed components. Finally, reconnect the battery and test the starter to ensure proper operation.
