I have an 03 grand am gt, there is only one way to check out the speed sensor, bring it to a garage and have them scan it for you... this will get it correct.
In front of the catalytic converter on the passenger side
bank 2 is the drivers side of the engine sensor 1 is somewhere in the exhaust before it enters the catalytic converter
Bank 2 is the drivers side of your Mustang engine Sensor 2 would be after the catalytic converter ( downstream )
