After finding places on google I was surprised the sensors have a cable. Just curious but where does the end of the cable go? And why I'm at it, can I assume the sensor is inside the tire?

I'm really not up for what appears to be more than a pain in the ****, I'm getting my 2007 Ltd. coupe ready to put on BAT (Bring a Trailer). I want to be able to say everything is working. Thus the need.

How would you suggest I go about it to get it done the easiest way. But hopefully not dealer time/costs. One dealer had my car two weeks to replace the (recall) steering wheel air bag.

How do you test for the faulty wheels sensor?
