    I then if you open the rear engine cover, it shows the vacuum lines and where they go on a label.

    how does the air injection work in the second drawing? It's not forced air like the US models but just sucks from the atmosphere?

    Yes, that's the air pumpless "pulse" air injection where the exhaust pulse draws in atmospheric air to the exhaust stream -- it was used on the circa 87~88 CH (Swiss) version TR. All US TR have the air pump style air injection system shown in Post #5.

    Hi
    Special thanks goes to you Gent's
    By the way, i cancelled the Catalyst system.I removed the whole exhaust US system and installed Koeing mufflers.And also cancelled the air injection with all its accessorizes.
    I found both MAP sensors.not connected with vacuum hoses.That is why i am looking for proper drawing.I Think Shamile send that vacuum sticker that attached to engine hood.
    Will come back to you .
    Thanks
