    This module comes with our USB Field Upgrade and Configuration Port! We recommend connecting it to a computer BEFORE YOU INSTALL and using our support app "m4cconnect" to do a quick firmware update check. M4cconnect as well as all other information regarding USB update and configuration can be found at You can even configure and activate your favorite module functions and settings on screen before the module is installed in the car! It is a good idea to permanently install the USB cable with the module in the car, leaving the computer plug in an easily accessible spot for later use with a Wifi/3G/4G connected laptop.

    If the top does not work properly or at all after installing the module, these tips can be very helpful:

    1) Turn Function 1 (Main Switch) off (Setting 0). The module will be completely passive. If the problem still persists and the top won't work, check all connections. Please also check the green DATA LED on the module!

    2) Function 2 now has a valet mode (Setting 2) on many modules. Valet mode completely disables opening of the top. Check the setting for function 2 and make sure the module is NOT in valet mode!

    IMPORTANT: Not all modules have the valet mode! Please check the Operation and Programming Manual!

    The DATA LED shows the module status and helps troubleshooting issues during installation:

    When the ignition is ON: The LED should BLINK (flash) in a regular pattern (about 1x per second). This indicates that the module is receiving data and should work OK.

    When the ignition is OFF: The LED should BLINK (flash) as long as the data bus is still active and turn off after a while (max 5 min) indicating that the car has entered stand-by (sleep) mode.

    If the LED is permanently lit with the ignition ON, the module is NOT receiving data from the top controller and all connectors should be checked.

    If the LED does NOT light up at all when turning the ignition ON, the module is either not getting power or not receiving ANY data. All connectors should be checked.
    Installation - Steps 1-3
    1. Fully open the top, then start closing it and stop when it is in the exact position as shown (service position). Move both seats all the way forward. Turn the ignition fully off.
    2. On both sides of the car remove the three screws (1), (2) and (3). Make sure to not drop and lose the little washer under screw #1.
    3. Grab under the rear "wall" cover on both sides behind each seat and pull forward hard. The cover is snapped into place in multiple spots.
    Installation - Steps 4-6
    4. Shown here are some of the mounting clips that hold the cover in place.
    5. Once the cover is unclipped far enough, the frame around the CD drive can easily be removed as well.
    6. Move the entire cover further forward. Shown here are a multitude of mounting clips.
    Installation - Steps 7-9
    7. Lean the cover all the way up agains the backs of the seats or (two man job!) lift it up and carefully lay it down on top of the folded roof. Make sure the seat belts don't get tangled.
    8. Directly above the CD drive is a wiring harness (1) which goes to an area under the carpeted cover. Follow this harness to find the convertible top controller (2) tucked underneath.
    9. There is a row of plugs on the bottom of the top controller. The red plug (1) and the black plug (2) need to be removed. Push the locking levers in while wiggling the plugs out. In case of problems inspect the corresponding plugs on the harness in order to understand the locking mechanisms.
    Installation - Steps 10-12
    10. Shown here the bottom edge of the top controller with both plugs removed.
    11. Connect the matching plugs from the module harness to the top controller, making sure they latch into place securely. In the foreground the module harness sockets can be seen.
    12. Connect the original plug (1) with the socket (2), then connect the plug (3) with the socket (4). Again make sure they latch into place.
    Installation - Steps 13-15
    13. Shown here the original plugs connected to the sockets on the harness.
    14. Connect the module with the harness and tap the unlock button on the remote once. The green DATA LED should blink to indicate a successful installation. Put everything back together and configure the module according to our Operation and Programming Manual.
    15. We recommend connecting the supplied USB cord to the module and running it into the center console through a gap (see arrow). That way the module can later be updated or easily be configured via a laptop without the need to take everything apart again.
