      2. Plug the SPADE into your truck using the OBD cable with the ignition on.
      3. Toggle over to Tuning Tool, press ✔️.
      4. Toggle down to Switch Tunes, press ✔️.
      5. Toggle to DSP4 and press ✔️.
      6. Toggle down to the tune number you wish to switch to and press ✔️.
        (This can also be done with the switch itself plugged in)

      If you get a Tune Switched Failed message reselect your tune and retry the tune loading operation.
