Mustang GT-2015 I was very hesitant about installing it myself only needed one as I had to use an emergency tire pump. After using the liquid, you need to replace the sensor. The old one was easy to remove, just pull it out. Installing the new one was a tricky job, it required pulling the sensor off the stem (just a tiny star screw) to avoid damaging the sensor while trying to install the blowgun part. I had to use a "robot arm" and a rag to force it through the rim to place it (make sure you line it up the same as the original one you pulled out, the sensor will point one way threaded into the valve stem). Then I bought a TPMS19 8C2Z-1A203-A transmitter to sync the sensor. I was afraid that if the frequency is turned off? What if txmtr is not configured for my computer? Txmtr worked like a champ, you need to re-sync all four even if you only replaced one TPMS sensor. Hope this helps others!
