Where is the probe plugged in for diagnostics?

Aldo- If in doubt, the first place to look is under the steering wheel. According to Tom of the Newton Street Garage in Brighton, Massachusetts, your plug is just underneath the steering column. If you were looking at the steering wheel and straight down is six o'clock, your outlet is at 4:30. Often if a manufaturer puts the connection somewhere else they will leave a sticker telling you where to find it. Good luck from bovan.
