    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.
    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.
    Installation - Steps 1-3
    1. Turn ignition off and pull key before installing. As an added safety it is good practice to disconnect one pole of the battery to avoid short circuits during installation! Open the hood and start by removing all screws around the two lids (1) and (2).
    2. Lift both lids up and remove all screws hoding down the plastic frame with the rubber seal. It needs to come out as well.
    3. The plastic tabs (1) that hold down the frame can all be bent sideways to release the parts they are holding down.
    Installation - Steps 4-6
    4. After removing screws (1) on both sides and unclipping the sensor box (2) the plastic frame should be free to be lifted up.
    5. Remove the entire frame to gain access to the white box in the left corner.
    6. Open the lid by sliding the locking lever towards the symbol of the opened lock.
    Installation - Steps 7-9
    7. Remove the cover to reveal the ECU and some relays.
    8. Everything needs to be removed from the holder. Disconnect plugs if necessary and pull the relays up, leaving them in their sockets.
    9. Lift the entire ECU carrier frame out of the box.
    Installation - Steps 10-12
    10. Turn the carrier over to cut two zip ties if desired, or move it to the side, with the wires still attached to it.
    11. Underneath there is a hole in the wall between engine compartment and passenger cabin. This is where the wiring harness to the piezo beeper has to be fed through.
    12. Go to the inside of the car and remove the two acrews (1) and (2) under the glove box. Then flip down the bottom piece and remove it.
    Installation - Steps 13-15
    13. Feed the wiring harness through from the engine compartment side. It will appear in the footwell.
    14. Pull the harness through so that the four pink plugs will reach all the way to the front of the control unit with the black and blue connector.
    15. Now route the module harness (1) through the hole by lifting up the grommet on the side of the ECU box. For better visibility the protective sleeves in this manual are WHITE, the shipped ones are dark grey or black.
    Installation - Steps 16-18
    16. Connect the speaker correctly, red wires and black wires with each other. Then use electrical tape if desired to secure the connections.
    17. Attach the beeper somewhere in the front in a protected spot (1) and run the wires through the wire-holder(2) so they run nicely alongside the existing wiring harness. This concludes the work in the front. Now everything in the engine compartment can be put back together the way it was. Install the ECU and all relays back in their positions, install the lids and plastic frame, making sure that all screws removed earlier are back where they belong.
    18. Back on the inside, install the separate module LED harness which needs to be run from under the glove box to the rearview mirror connector. Start by removing the cover over the screw in the top left corner of the A column.
    Installation - Steps 19-21
    19. Remove the screw underneath.
    20. Pull the rubber door seal out just enough so the side piece can be easily removed.
    21. Pull the side piece up and out to reveal an existing wiring harness.
    Installation - Steps 22-24
    22. Open the side of the dashboard to gain access to the inside.
    23. Use the supplied extra wiring harness and run it from under the glove box up to the rearview mirror. The end with the two metal pins goes to the mirror, the end with one metal pin and a pink plug goes under the glove box.
    24. Attach the harness to the existing one if desired. Again, for better visibility the module harness shown here is WHITE, whereas the shipped version is dark grey or black.
    Installation - Steps 25-27
    25. Take the plastic cover under the mirror off. It splits nicely apart in the middle when pulled in the directions of the arrows.
    26. Underneath it the rain sensor and the wiring from inside the mirror become visible.
    27. Grab the connector hidden inside the mirror holder and pull it out. Disconnect it pull the end coming from the ceiling towards you.
    Installation - Steps 28-30
    28. With a small screw driver open the locking latch as shown, to allow contact pin insertion and removal.
    29. Check the existing wires. There should always be a brown/black (ground) wire in slot 10. If there is NO wire in slot 9, install the grey/black wire from the module harness here. If there IS a wire installed in slot 9, remove its contact and replace it with the one from the module harness. If there is NO wire in slot 8 (+12V power), install the red wire from the module harness and use the pink plug later in step 30 to supply power to the LED in the mirror. If there IS already a power wire in slot 8, LEAVE IT in place and DO NOT use the red wire from the module harness as well as the pink plug in step 30. Use electrical tape to protect any unused contacts and put everything back together here.
    30. After running the wires nicely from the mirror down along the side, putting all covers and rubber seal back into place, take both module harnesses now located under the glove box and insert the contact pin with the grey/black wire (1) exactly opposite the grey/black wire coming from the module (marked with slot no. 5). If the red wire was used in the previous step, attach the supplied wire tap to the red/yellow (+12V) wire and attach the pink plug (3) to it. If the mirror already had a power wire going to it, there is no need to tap power here.
    Installation - Steps 31-33
    31. Remove the BLACK connector from the control unit under the glove box by first pushing in the locking latch, then moving the eject lever to the right. IMPORTANT: Always use the BLACK plug. On some cars the control box is mounted upside down so the black plug will be on the right.
    32. Slide the cap off the connector. it is held in place by tabs (1) on both sides. Use a small screw driver.
    33. Tap and connect the following wires: Brown (pin 6) for ground, red/blue (pin 3) for permanent 12V, orange/green (pin 10) for CAN Bus and green (pin 12) for CAN Bus. The CAN Bus wires should be a twisted pair, so pull them apart enough to attach the wire taps. Lastly, connect the four pink plugs from the module to the taps. Red/yellow is +12V and connects to red/blue, all others have matching colors. Make sure the metal contact blades actually slide INTO the slots (see "most common problem" section at beginning of this manual). Connect the remoteKEY module to the 16 pin plug on the harness, then put everything back together, connect the battery and tap the unlock button on the remote. The green LED on the module should blink to indicate a correct installation.
