    Not my first time on here with wire issues. Last time was because of human screw up, this time because of a pest.

    This is a 2009, second generation Prius.

    Here's the part that got chewed through. If someone could identify the part I need, or the wire types I need to buy, I'd appreciate it. I have all the tools already for crimping and connecting wires from last time, at least, so that's one bonus lol.

    The hood latch also broke simultaneously which I imagine is going to be much more annoying to replace than this wire connection.

    In case anyone is wondering, the sensor is called a Prius Inverter Circuit Breaker Sensor. It's also called Circuit Breaker Sensor #1 by the official online Prius Parts Center. The part number is G4845-47020.

    I can't seem to find it anywhere except for Ebay and the official Toyota stores. I'd like to just drop in some local car shop but looks like that's a no-go.

    I don't see any sign that anything bad happened to the circuit-breaker sensor itself, only to the two wires connecting to it.

    If you're just going to use splicing materials you already have on hand to repair those wires, there may be no need to look up any parts.

    You could buy Toyota's repair terminals for the yellow connector, and if you wanted to do that, you could find the part numbers in the online wiring diagram, as this post describes.

    But I don't see any advantage to doing that here. The repair terminals come with short lengths of wire attached, which you still have to splice to your original wires; the usual lengths would put the splices just about where you could just splice what you've got already. I don't see any sign of damage nearer to the terminals or connector.
