    Hi everyone, it's awhile lurking around here.
    A friend bought a 2015 Prius XVW 30 on an auction site from the USA, and shipped it to Lagos, Nigeria, where it was towed to my shop.
    On taking a physical check at the interior of the vehicle, it had signs of flooding, up to the seat levels.
    The owner told me he didn't know the vehicle was a flooded one, because I had to confront him to asked why he bought such a vehicle. He responded saying, he also didn't realise it was flooded. I find that information has to believe.
    By the way, he decided he wants to fix the car.
    I have done the following:
    1. Replaced all the modules under the passenger side pigeon hole (power management control, smart key module, etc), and also the driver side multiplex interior fusebox with used ones. I plan to reprogramme the HV ECU, when I am done repairing some of the dashboard interior wire harnesses, which I have completed.
    2. Engine side wire harnesses are perfect.
    3. Engine not hydrolocked, because I manually turned the engine full revolution.
    4. Gasoline in the tank, wasn't contaminated by the flood waters when they purchased it.
    Since I couldn't get the front left and right side floor body wiring harnesses, I decide to kinda attempt to repair the wires by joining them.

    CHALLENGE
    I am finding it difficult to connect some of the wires, for example, that came from the front end of the driver side front floor wiring harness connector, because almost all the pinouts have fallen off from the male and female connectors.

    Can anyone also help with the wiring diagram of this harness to the male connector, and it's female part?

    Here is the part number of the front left side floor wiring harness ( 82161-47B52). But I seem not to know, or have the part number of it's front end connector.

    Please can someone point me to the wiring diagram for the pinouts, so that I could just connect the wires straight away, without the connectors, since they are corroded?
