    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!
    Installation - Steps 1-3
    1. Before beginning with the installation, fully open the convertible top, then start closing it and stop when the top lid is open as shown, right before the top itself comes up. Turn the ignition fully off.
    2. Remove the two T30 torx screws (1) and (2) from the center cover piece to be able to remove it. It has two more plastic snap-in retainers on the back.
    3. View from the back where the two plastic retainers need to be removed. Best way to remove them is by using a flat bladed screw driver or trim removal tool and pulling the center part out. Then carefully pull them straight out towards the back while wiggling.
    Installation - Steps 4-6
    4. Directly underneath the center cover is the top controller module. The rightmost plug (1) needs to be disconnected. Pull out on the red tab while pushing it down and wiggling the plug out of the socket.
    5. The grey plug fully removed from the top controller.
    6. Install the Mods4cars T-Harness by connecting the grey plug (1) from the harness to the top controller socket (2) and the original grey plug (3) to the matching socket (4) on the harness. Connect the SmartTOP module itself to the 16-way connector. Make sure all plugs latch securely into place.
    Installation - Steps 7-9
    7. Turn the ignition on and check the green DATA LED (1) on the module. It should blink to indicate a successful installation. We suggest connecting the USB cord as well and leaving it accessible (2) after re-installing the center cover plate. You can attach the SmartTOP module to the face of the top controller module with the supplied velcro sticker. Don't forget to configure the module according to our Operation and Programming manual.
    8. Plug the little OBD chip into the OBD socket under the steering wheel. This is important as this is the piece that allows the windows to close automatically.
    9. The OBD "Window Close Chip" (1) can be quickly removed when access to the OBD port is required. The SmartTOP will still work without it, but the windows can not close at the end of the top cycle. In cases where other logging equipment needs to be connected to the OBD as well, a Y-splitter cable can be used. REMEMBER TO ALWAYS PULL THE CHIP AND DISABLE THE SMARTTOP MODULE (Function 1 Setting 0) BEFORE TAKING THE CAR TO A DEALER FOR SERVICE!
