No one has said where in the tire or rim the TPMS should be mounted. It should be mounted 180 Degrees from the Valve stem so you will know the location to place your testing or programing device. Of course in many cases the TPMS is mounted in the place of the valve stem.
One major suggestion to check for tire leaks put about 2 Oz. of dish washing soap in some sort of extra spray bottle and fill it a little over 3/4 with water. Then make sure the tire to be checked has the correct air pressure and began spraying the leaking tire Even all over. If it is lousing air you will soon know where if you fine one place don't stop until you have wet the complete tire and rim don't forget to mark the leaks. Happy Hunting!

 

You can the straps at AutoZone or Advance auto supply they are not original but work fine.

 

I'm not reading the whole thread again, but yeah, you need to have the sensor 180 degrees from the stem. This is so the tire warehouse deck ape knows where to bust the bead with the machine. This is how come so many sensors were wrecked in the beginning of the TPMS era.
