is the mps mounted on the motor or somewhere inside the engine bay?
The MPS (Manifold Pressure Sensor) is typically mounted near the battery tray on a bracket welded onto the upper portion of the suspension console.
It is an aluminum can approximately the size of a coke can (but only about 3/4 as high as a coke can). It has a single hose attaching it to the intake plenum near the throttle valve.
The MPS and the ECU are matched together. (refer to Brad Anders info pages)
The 1.7 has a similar (but not interchangeable) MPS mounted in the same area (the outside appearance is identical).
