Traction Control Sensors

I am setting up a car that did not come with any wheel sensors for traction control. What type of sensors do i need to buy that will work with the Proefi 128?

I just pick up some Turck 3 wire porx sensors, they should give a nice square wave signal. I have notice on the Proefi 128 there are only two inputs for wheel sensors. J1 A01 for driven and J1 A12 for non-driven wheels. So I have purchase four wheel sensors and not sure how to connect all four to the Proefi or do i need only two sensors, one on a driven wheel and the other on a non-driven wheel? If only using two sensors, what side of the car would be best, left or right?

on most cars, proefi comes configured to read left front and left rear.

dunno about appropriate sensors though

You only need 1 driven and 1 non driven sensor. Digital square wave is fine.
