the pictures seem clear to me...?
-connect intake tube with the coupler to the intake mani
-connect the hose from the nipple of your intake tube to the nipple of the head at the top left corner.
-connect your IAT sensor in the rubber piece on your intake tube
-then reset your ecu
that's about it...
edit:
here's a pic of mine if it's any clearer... you can't really see the back where you would connect the IAT sensor but eh, you should get the idea.
