I have a Rapid Velocity Performance chip. I am trying to install it on my 2007 Ford Focus ST. This is the 2.3 engine. I dont know where the IAT or CTS is located, (these are the two locations it can be installed). I would preferr the IAT install because that is where it is suggested to be installed. Can anyone help me out. A diagram would be great. If not, where its located and the wire colors will be fine. Please Help

Ok here's your installation instructions - 1/ walk over to bin 2/ lift lid and install chip 3/refit lid.
Unless it brand new in which case send it back. These things will have no effect on modern vehicles as the PCM will realter fuelling etc to compensate when it sees other sensors are not altering in line with whatever readings are being produced by this gadget.BTW the new Focus ST (same as mine) is a 2.5.
