The connector is for the temperature sender.
It's not important what the application, the connector can be robbed from other Honda's in a salvage yard. Or you can try Cycleterminal.com, but crimping connectors require more tools. Much easier to just get a used connector and use generic butt connectors and crimps.
And the other is a vacuum hose, available at any auto parts store....but if you are already in a salvage yard, just get a length of matching hose in good condition from the donor car.
Your best bet it to get a matching connector with a length of wire attached, the hose, and take the car to an auto electrical place...they'll have you connected up in a few minutes with some waterproof connectors.
