Also do you require vin number when ordering as I heard rumors that the frequency got change by 0.1 during 2010 manufacturing year causing intermittent problems with connection cutting in & out. thanks

Hello
When just sitting around they are in a "sleep mode" so there really is not battery draw until they are woken up via movement. As for frequency they are really only 2 variations a US and foreign version other than that there are not different frequencies that would require an different sensor
