    The rear diff breather is easily located. Can anyone tell me where the other 2 are? I’m thinking the tubes terminate in the engine bay. I assume there should be a black tube with a silver vent cap on the end for each component. So there should be 2 tubes unless they connect with a Y type (2 into 1) tube connection. Thanks

    I can’t find them? Attached pics. Anyone have a pic? How high up are they relative to fuse box?

    You got a 5th gen? Should be to the Left/Below the Relay/Fuse box -- here's a couple of pics

    Yea, I found them. The top of the silver caps were being partially blocked by the bottom of the fuse box. I was looking for your orange cables and realized you must have some power supply modifications. Thanks so much

    No worries -- glad to help out -- that's one of the things I love about this forum -- all the people willing to help me out with my OCD questions -- LOL

    BTW, no mods on my Runner other than tires.

    There are actually 4 breathers under the hood. The two shown by the fuse box, and two more behind the motor at about the same height of the first two.

    Captain Spalding, are the other 2 more easily seen from the passenger side of engine compartment? I’m guessing one is the ADD Actuator and one it transmission?

    I could only see the ones behind with a mirror. I think those are transmission and transfer case, and the ones by the fuse box are for the front diff and add. I’ve never actually chased them down to confirm which goes with which.

    I found then using mirror from passenger side. They are shown as silver caps in attached picture.

    This last pic actually has 3 breathers in it. I believe the white plastic cap looking thing next to the two metal capped breathers you are talking about is actually the transmission breather.
