    The connectors im holding with my hand, im not sure where they belong.

    I think the connectors in the first photo just need a ground. They're on the drivers side near the intake.

    The white connector in the second photo i have no idea in the slightest what it connects to. its on the passenger side near the intake. it for sure does not go to the throttle body.

    Peeps of prius chat, where do you think these go?

    Who is the ding dong who disconnected those wires?

    Did the car come back from the body shop?

    Are there are warning lights? Is there some equipment not working?

    Compare your car to another Gen 2, preferably same year and options. Track the unknown wires down, to see if the other Gen2 has those same wires and where the wires terminate.

    Next time label wiring ends and the corresponding attachment point.

    Mark the same number on each side w/ a sharpie.

    Make a note on a master sheet somewhere where the wire was nearby and what it connected to.

    Pictures too. This will serve as another backup source and visual clue. should ypuraster list get lost or tape should come off.

    Refer to Toyota’s Electrical Wiring Diagram book for the 2005 Prius (EWD599U), available from eBay sellers or by subscription to techinfo.toyota.com. For model year 2005, portions of the book are also available on the ChiltonLibrary service, to which your local public library might sponsor free access for its patrons.

    I found where they go. The white one is for the knock sensor and the ground cables mount to the passenger side of the head.
