    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 www.mods4cars.com/usb. 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.
    IMPORTANT TROUBLESHOOTING TIPS

    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 green InstallAID™ LED signals a correct installation and shows the status of the module. On new modules this LED is labeled with DATA.

    LED OFF
  • Ignition OFF: CAN bus and module are in low-power standby mode. This is normal.
  • Ignition ON: Either power connection or CAN bus connection is interrupted. Check the two wire taps for power and ground as well as the CAN connectors. Also make sure the CAN polarity is correct.
    LED either dimly lit or flickering erratically
  • A dim or flickering LED is an indicator for interrupted or missing POWER or GROUND connections. The module will get some leakage current from the CAN bus which causes the LED to stay dimly lit or flicker erratically. See previous paragraph about wire taps if applicable!
    LED permanently ON
  • Module is connected to CAN and power, but does not receive the correct data. Recheck all connections thoroughly. A VERY COMMON source of problems is reversed polarity on the CAN wires. Double-check the POLARITY and wire-colors of all connections!
    LED blinks
  • CAN bus is active, the module is connected correctly and ready for use.
    • USE OF THE 3M WIRE TAPS
    This module is installed using the 3M wire taps very popular with 12V aftermarket industry for their reliability and durability. The most common problem during installation is a bad contact between the plugs from the supply wires and the wire taps. Please make absolutely sure that the metal blades of the plugs slide into the slots of the t-taps. It happens that the blade "misses" the slot and the connection looks correct, but doesn't make electrical contact!

    The T-taps come in RED (for thin wires), BLUE (for medium wires) and YELLOW (for thick wires).

    To test if you installed the module correctly after all wires are connected, turn the ignition fully on and watch the green LED on the module. It should blink (flash) to signal a correct installation. If the LED either does not turn on or stays on permanently, there is a bad contact or a missing connection! See detailed explanation of the DATA LED.
    USE OF TYCO AUTOMOTIVE CONNECTORS
    THE PHOTO IS A SAMPLE AND ONLY SHOWS WHERE TO FIND THE NUMBERS AND HOW TO INSERT THE PINS. SOME CARS REQUIRE THE RED AND BLACK WIRES REVERSED! PLEASE FOLLOW THE BELOW STEPS FOR CORRECT WIRE ASSIGNMENTS!!!
    The wiring kit for this module uses one or more of the TYCO connectors shown on the left. These are specialty automotive connectors designed for tight and secure electrical connections. In order to avoid reversing polarity, please pay attention to the small numbers embossed in the back of the plugs where the contacts are inserted. In case one of these plugs will need to be removed later, it can be done without any damage to the plastic cap or the crimp contacts. Please see our Knowledge Base article(s) regarding these plugs at http://mods4cars.com/support/knowledgebase.php?search=tyco.
    Installation - Steps 1-3
    1. IMPORTANT: Turn ignition off, and pull key from ignition lock before installing the module! Remove side carpet cover strip in passenger footwell. Pull the trip towards the back of the car, it is only snapped in place.
    2. Remove all 5 screws from the pastic cover underneath the glove box.
    3. Just behind the cover is a control unit with two large plugs connected to it. Remove any cable-ties if present.
    Installation - Steps 4-6
    4. Remove the left plug by pushing the white lever to the left.
    5. Pull the plug out all the way and remote the black cover from the white insert. There are latches (1) on both sides.
    6. Remove a good portion of the fabric tape to gain access to the individual wires going to the plug.
    Installation - Steps 7-9
    7. Attach the supplied wire taps to the thick red-yellow (1) and the thick brown (2) wire. Then remove the two contact pins for the yellow (3) and black (4) wires from the plug. Use a small screw driver or needle to push the metal latches in while carefully pulling on the corresponding wire.
    8. Replace the wires just removed from the plug with the ones from the module harness. Brown replaces Yellow and Orange replaces Black.
    9. Insert the yellow and black wires into the first one of the supplied caps (1). Insert Black in slot 1 and Yellow in slot 2 (numbers on rear of cap). Then insert the green and blue wires into the second cap (2). Green in slot 1 and blue in slot 2. These wires are not used in this installation and are protected this way.
    Installation - Steps 10-12
    10. Now connect the plug with the yellow and black wires to the counterpart from the module harness that carries the brown and orange wires. Brown faces Yellow and Orange faces Black.
    11. Connect the Module to the harness and the power connectors to the taps. Red (+12V) connects to Red-Yellow and Brown (ground) connects to Brown. Slide the black cap back over the plug and reinstall the plug on the control unit. Make sure the white lever clicks into place.
    12. Turn the ignition on and watch the LED (1) on the module: It must show a constant blinking pattern. See paragraph about InstallAID LED. Last, put everything back together in the reverse order of removal. Done.
