    Does anyone know where I can find the wire that feeds electricity to the parking lights? I want to tap into it so I can add an Led windshield washer jets and have them turn on whenever the parking lights are on, but, I need to find a wire thats located inside the car, preferably within the dash, not under the hood. Is there such a wire? If not the parking lights, is there a wire I can tap into that feeds the fog lights that are within the dash? Thanks a lot to anyone who can help!

    All the tail/sidemarker light power leads are brown wires coming out of the driver junction box. There are several. There may be other brown wires for other purposes, so I suggest cheking with a voltmeter to ground. All the lights are serviced with a 10A fuse.

    so if i connected 12v LED to the brown wire from the junction box that connects to the parking lights, they will light up? I dont know anything about electronics, but will connecting an extra light like an LED to this wire cause a decrease in power to the parking lights?

    I'm having trouble understanding why you'd want to take a power
    tap for your snake-eyes from inside the cabin, because the
    firewall is rather difficult to find a path through.
    You'd probably be best off bringing a tap off one of the
    parking-light leads and following the squirter
    hose up to your nozzles. So in that case, one of
    the brown wires that go to the lights. Since there are
    a lot of brown wires in the under-hood harnesses, make sure
    it's the right lead.
    .
    If you really want illumination power from inside, the grey
    lead to the display-brightness rheostat comes from the
    7.5A "PANEL" fuse and should be plenty to power a couple of LEDs.
    .
    If you want to get more in-depth than that, I highly
    recommend having the electrical wiring diagram [EWD] at the
    very least, and the physical connector map. See
    techinfo.toyota.com...
