FAKRA (SMB) Connector Information and Specifications

FAKRA Connectors are designed for automotive applications and are based on the SMB connector interface and comply with the standard for a uniform connector system established by FAKRA (FACHARBEITSKREIS AUTOMOBIL – German group of experts from vehicle manufacturers and equipment suppliers). Due to their special standard locking system FAKRA connectors fulfill the high functional and safety requirements of today’s automotive industry and are specified for 6 GHz in 50 omh or 60 ohm. These connectors are commonly used in GPS antenna, Engine management system, Analog/Digital radio, Auxiliary heating, TV/Video-displays, Antenna, Distributor box, Accident data analysis, Mobile phone, Remote control keyless entry, Distance control, Air pressure control, and Navigation systems.

The connectors are equipped with a standardized coding system which permits easy and fast assembly using fourteen possible coding options. The locking system has primary and secondary locking to prevent inadvertent detachment.

The FAKRA standard is described today in the DIN 72594-1 / ISO 20860-1 and harmonized with the USCAR-17 standard and the goal is to transfer the DIN and USCAR standard into an international ISO standard. USCAR-17 is meanwhile replaced by ISO 20860-1 and the same will happen with DIN 72594-1.

Addition of extra circuits to the Volkswagen Golf / Jetta / Passat / EOS / Scirocco / Rabbit fuse box

Adding new circuits to your Volkswagen Golf / Jetta / Passat / EOS / Scirocco /Passat fuse box is reasonably straight forward, allow 2 hours for the first time and 1 hour for each time after that.

(Golf 1K1 /1K5, Golf Plus 5M1, Passat 3C2/3C5, Passat CC 357, EOS 1F7, Scirocco 137)

There are two sizes used in the interior fuse box, ATM and ATO size. These are commonly referred to as Mini and Standard. In the main fuse box there is an additional type called ATX but commonly referred to as Maxi.

Repair Wire or Terminals for additional circuits

To install new circuits you require either repair wire (two terminals on the end of one short cable, cut the cable in the middle and join the two cables to the new circuits) or terminals (not recommended see below for details).

The small fuses in the fusebox use the 2.8mm terminals. The terminals are the same size but the repair wires are different sizes. I used the 1.0mm wire size for this guide.

  • 000 979 021 (000979021): 0.5mm wire
  • 000 979 133 (000979133): 1.0mm wire (used for this guide)
  • 000 979 225 (000979225): 2.5mm wire

Crimp on pins are available as well but I recommend the repair wires unless you’re familiar with the crimping process:

  • N 906 844 05 (N90684405): for 1.0mm wire
  • N 906 845 05 (N90684505): for 2.5mm wire

The large fuses in the fusebox use the 4.8mm terminals. The terminals are the same size but the repair wires are different sizes. These were not installed in this guide but the process is identical.

  • 000 979 023 (000979023): 0.5mm wire
  • 000 979 135 (000979135): 1.0mm wire
  • 000 979 227 (000979227): 2.5mm wire
  • 000 979 306 (000979306): 4.0mm wire

Crimp on pins are available as well but I recommend the repair wires unless you’re familiar with the crimping process:

  • N 907 326 03 (N90732603): for 1.0mm wire
  • N 907 327 03 (N90732703): for 2.5mm wire
  • N 906 966 03 (N90696603): for 4.0mm wire
  • N 904 221 02 (N90422102): for 6.0mm wire

Fuses available and their colours are listed at the end of this guide.

Using repair wire to connect to your new circuits.

Cut the repair wire in two as shown, I recommend unequal length so the two soldering joints are not adjacent to one another.

volkswagen_fuse_box_repair_wire_1

Twist the connectors together and solder as shown keeping the joins as small as possible. Ensure that you have installed the heatshrink tubing on the cable before you solder!

volkswagen_fuse_box_repair_wire_2

The finished product should look like this.

Installation of new circuits

This guide is for RHD Volkswagen Golfs, the LHD fuse box removal is easier and does not require the removal of trim.

Important: Make sure all the doors are unlocked, the key is not in the ignition and disconnect the car battery.

Start by removing the cover over the fusebox,  a small notch is visible 2/3rds of the way down on the side where you can place the ignition key and lever this off. Once this has been removed you will see the fuse box.

volkswagen_fuse_box_before

Next remove the two clips as indicated, these can be pushed out from behind with your finger.

volkswagen_fuse_box_before_main

Remove the headlight switch by pushing the knob inwards when on Auto and turning it around to the off position.

volkswagen_fuse_box_trim_headlight_switch_1 volkswagen_fuse_box_trim_headlight_switch_3

This will allow the locking tab to withdraw.

volkswagen_fuse_box_trim_headlight_switch_2 volkswagen_fuse_box_trim_headlight_switch_4

Remove the screw at the rear top.

volkswagen_fuse_box_trim_headlight_switch_remove_screw

Remove the drivers side drawer by opening it and pressing the sides together at the back to release it and once open you can remove the drawer by unclipping the hinge. Remove the two screws at the bottom and the one at the top.

volkswagen_fuse_box_trim_storage_box_1 volkswagen_fuse_box_trim_storage_box_2

Pop the trim above the steering column by using a trim removal tool, be careful not to scratch the trip around the instruments as there is a metal clip on the rear of this trim.

volkswagen_fuse_box_trim_above_steering_column_1 volkswagen_fuse_box_trim_above_steering_column_2 volkswagen_fuse_box_trim_above_steering_column_3

Remove the screw and sit the trim back in place.

volkswagen_fuse_box_trim_above_steering_column_4

The trim panel can now be removed and the fuse box can be loosened by undoing the screw on the top and bottom of the fuse box.

volkswagen_fuse_box_before

The fuse box is now loose.

volkswagen_fuse_box_open_1

Pull the label forward (don’t remove it) to uncover one of the three sets of clips holding the cover on.

volkswagen_fuse_box_open_2

Gently unclip the three clips around the cover.

volkswagen_fuse_box_open_3

Remove the fuse box cover and expose the rear of the fuse box.

volkswagen_fuse_box_open_4

The next step requires removing all your fuses, as nearly every fuse box is different it is essential you document the fuse layout, at the very least take photos and even write them down.

volkswagen_fuse_box_open_5

These are the two locations where we will be installing our connectors and creating our new circuits.

volkswagen_fuse_box_open_6

Insert a small flat head screwdriver where indicated and move the carrier downwards as indicated to enable the connectors to be unlocked.

volkswagen_fuse_box_open_7

Insert the repair connectors as shown.

volkswagen_fuse_box_open_8

The carrier has been slid back into place to lock the connectors.

volkswagen_fuse_box_open_9

The new circuits have been run in along the same path as the factory loom.

volkswagen_fuse_box_open_10

Snap the cover back into place.

volkswagen_fuse_box_open_11

Refasten the fuse box into place.

volkswagen_fuse_box_open_12

Reinstall the fuses including the new fuse(s) if the circuits are connected or have been isolated.

volkswagen_fuse_box_open_13

Reinstall the trim following the removal instructions in reverse and place the cover back over the fuse box and reconnect the car battery.

Note! When used with a sound amplifier, the same pin assignments are used as line-in for the sound amplifier. To achieve this, the radio unit is programmed from “output stage power 26 dB” to “output stage line-out 12 dB” in the factory. Details on how to perform this can be found in Volkswagen RNS 510 coding when installing with a factory amplifier.

amplifier_pin_assignments_N91-0336

The sound system amplifier extends the sound range of the radio unit or radio navigation system.

It is available as optional equipment for appropriate radio units and radio navigation systems.

The amplifier is an 8-channel system.

The signal inputs on the amplifier are activated by the loudspeaker outputs of the radio unit or radio navigation system.

The amplifier is installed under the left front seat.
