Please help me identify where these connectors plug into

The larger one is on the drivers side under the dash and the smaller on the passenger sider under the dash

 

Looking through the 00-05 Electrical Troubleshooting manual, my best guess is that the smaller
one is for the blower motor, and the blue one is C302 "connects left-side engine compartment wire
harness to dashboard wire harness B (left branch)"
