99' Bonneville. I need to test the wires connecting to the wheel sensor connector but I don't know how to use the multimeter I have. Could someone tell me what setting I need to put the meter on and what am I looking for? I don't know anything about the meter I have.

99 Pontiac Bonneville se .... has anyone ever re-soldered their own ABS control module? If so how exactly did you do it? I see YouTube videos on doing it yourself. Finally what is the make and model for my particular ABS module?

Have no idea why on the hwy. the car is wanting to pull to the right violently and the steering wheel is shaking big time. Tires appear fine. Would the motor mounts be involved and if so how do you check them and how many are there?
