When using towing hook mounting, you can still use MD30EXTSET to mount the air temperature and humidity sensor HMP113 and surface temperature sensor MT10 elsewhere on the vehicle for optimum performance. In that case, install them last. See Mounting Temperature Sensors Separately Installation Guide.

  1. Remove the pre-installed mounting bracket (MD30BRACKET).
  2. Loosen the 8 screws (M4×10) that hold the temperature sensors HMP113 and MT10 in place and remove the sensors.

    Their cables can remain connected during the assembly.

  3. Assemble as shown using the provided brackets and M4×12 screws. Check carefully which way to mount the brackets.
