KUFATEC 40665 Complete Set Active Sound incl. Soundbooster
Liability Exclusion
Dear Customer,
our cable sets are developed according to the connection- and circuit diagrams
of the corresponding car manufacturer. Before the original production the
cable sets will be tested on an original car. Therefore, the integration into
the car electronics will be executed according to the instructions of the
manufacturer. Regarding the necessary pre-understanding and the accuracy of
the presentation of texts and pictures our mounting guidelines correspond to
the usual ones in car technology and car electronics. Practically, they have
been proved one’s worth a hundred times.
However, should there be any difficulties during the installation of our
products we will be at your disposal any time for support by phone or by mail.
Moreover, we offer you to execute the installation at our works in Bad
Segeberg.
Costs which may arise because a third person will execute the installation of
our products will not be supported by us in any case. Only if there is a
mistake caused by our product we will pay the proved costs of the installation
as well as the costs of the removal of the defective product. The refund of
expenses will be limited to gross EUR 110,- ; we reserve the right to check
the described mistake in our works in Bad Segeberg. In case of a proved
reclamation the costs for dispatch for the check in our factory will be
transferred to you.
According to our experience each specific factory which has the necessary
diagnostic device, diagnostic software and the circuit diagrams of the
manufacturer can find possible mistakes at our products within a short time.
So the installation and removal including diagnostic inspection can be
realised in at most 60 minutes.
We also made the experience that many specific factories cannot work with the
circuit diagrams of the manufacturer, and that they cannot read usual wiring
diagrams. Therefore, very easy installation works will take many hours. You
will understand that we neither take the risk to find a reliable specific
factory nor the financing of the training of the staff of your favoured
factory.
Costs which will arise because you buy missing parts or spare parts at other
suppliers will be refunded by us up to the amount of the costs which had been
arisen by additional supply (saved expenses). In this case, there would be no
right for refund according to the legal guarantee right as long as we have no
deadline for supplementary performance or a deadline for supplementary
performance has not expired.
So if you have any problems with the installation or operation of one of our
products please call us, send us an email, send us the product or take your
car to our factory in Bad Segeberg. We are sure to find an appropriate
solution for each concern.
With best regards
Your Kufatec GmbH & Co. KG Team

Remove the carpet in the passenger’s footwell as well as the trim panel below
the dashboard and of the a-pillar at the bottom (Fig. 1). For this, it is
necessary to remove the sill trim, Fig. 2.
Connect the Can wires with the white plug of the comfort control unit below
the dashboard at the a-pillar, fig. 3, as shown below. For this, loosen the
interlock of the plug and move it off. Remove the plug housing to be able to
read the Pin numeration and establish the connections as named below, fig. 4.
Can High (black/white) – Pin 36 (blue/red)
Can Low (black/yellow) – Pin 35 (red)
afterward insulate the wires with insulating tape.
Connect the ground cable (brown) afterwards. A suitable ground spot is located
in the passenger’s footwell, fig. 5 and 6. 
Connect the wire for ignition plus (red/white) with the yellow/green wire of
the cable harness at the fuse carrier in the trunk (below the covering), fig.
7. Loosen the fuse carrier to establish the connection at the back side
according to fig. 8. Insulate the connection point afterwards and protect the
wire with 7,5A. Check the correct connection to ignition plus with a
voltmeter! 
Install the two control units with suitable workshop material in the area of
the right a-pillar below the dashboard, fig. 9 and 10.
Route the cable on the passenger’s side under the sill trim and behind the
b-pillar, fig. 11 and 12. 
Afterwards route the wires below the rear seatback, fig. 13, along the rear
right wheel housing (use a pull through aid for this), into the trunk, fig.
14. 
Route the wires to the driver’s side below the trunk floor covering, fig. 15.
Afterwards route the cable behind the left side trim panel (use a pull through
aid for this), fig. 16. 
Now guide the cable behind the left side trim panel, through an existing
grommet, outwards, fig. 16 and 17. Ensure a
waterproofing.
Remove the trim panel of the underbody rear left, fig. 19, and make an opening
according to fig. 20. 
Install the sound generator at the hold point for the exhaust silencer
according to fig. 21 and orientate it before the tightening of the fixing
screw according to fig. 22. 
Connect the external sound generator with the just routed cable, fig. 23 and
24, and attach the cable with cable ties. 
As additional safety the delivered steel cable and the retaining clips have to
be tightened on the Sound Booster as well as at a suitable position in the
car. This safety cable is an additional security should the tightening screws
should be released by vibration.
Please use for the fixation of the Sound Booster suitable high tensile screws.
In order to avoid loosening of the screws by vibration please make the screws
safe with appropriate factory material e.g. thread lock. Please additionally
check the stability of the Sound Booster regularly and if necessary retighten
the screws.
In case of no consideration, we do not assume liability for possible damages.
Finally, you have to route the wire of the pushbutton for the switch of the
sound profiles. Use a pull-through aid for this and route the wire from the
passenger’s footwell behind the center console into the driver’s footwell,
fig. 25. We recommend the installation of the pushbutton below the dashboard,
at a non-visible position, fig. 26. 
The reassembly is made in reversed order. See to a can bus sleep mode of at
least 10 minutes (lock vehicle). Thereafter the installation is completed.
You can switch the sound profiles with the push button. You can choose between
6 sound profiles. In profiles 1-3 you hear a restrained sound, in profiles 4-6
it’s a powerful V6/V8 sound.
