Part No.: EA 12.1
Risk of serious injury or death!
Do not allow cargo or a folding rear seat to interfere with or
misdirect the harness belt tail straps.
This harness restraint is manufactured and approved in accordance to the
European Standard ECE-R 16.04 and/or FMVSS 209. This TAKATA asm harness
belt is only suitable for adults on front outboard seating positions.
Risk of severe injuries or death.
TAKATA harness belts will function properly only when installed in
vehicles equipped with seats having a headrest or backrests with
seatbelt openings in an integrated headrest. Otherwise the
shoulder belts will slide off occupant’s shoulders during an accident.

INSTALLATION
1 General Instructions
Only install DRIFT if rear seat occupation is not intended at any time. The
crossing shoulder straps restrict the rear seat capacity because the tail straps
cannot be released.
Risk of severe injuries or death. On 2-door vehicles the folding front
seat backrests will be restricted in their range of motion.
Evacuation or rescue of rear seat passenger can be restricted or
even impossible after an accident. Do not transport rear seat
passengers in 2-door vehicles while harness belt is installed.
1 2

Always leave original equipment seat belts in place and available for use.
Never install shoulder
belts directly to the
floor behind the seat!
Anchor Points, Bolts and Threads
These harness restraints are designed for installation to OEM stock anchor
points providing threads with the dimension of 7/16“ 20 UNF. Bolts supplied
match with this 7/16” 20 UNF thread size. Self-drilled holes may be too weak
or may be in an incorrect or dangerous geometrical location. TAKATA does not
take any responsibility for the adequate performance of such anchor points.
Always check for the proper length of bolts used, the stock thread must be
fully filled by the bolt. Tighten 7/16” bolts with a torque of 40 Nm [30 ft-lb].
Incorrect thread dimensions, using bolts that are too short or not
properly tightened bolts may result in belt failure during an
accident. Severe injuries or death may occur.
Lap Belt Anchor Points
1. Anchor points to the car centre/middle
They are either located to the centre tunnel or to the seat structure close
to the seat rail.
2. Outer/Outboard anchor points
They are either located to the door sill or to the seat structure close to the
seat rail. In case of a 2-door car with a lap belt slide-bar at the door sill, use
the front slide attachment point for harness restraint door side lap belt
installation.
Shoulder Belt Anchorages
1. Shoulder belt anchor points for harness restraints with 2 tail straps.
The rear seat lap belt anchor points [D & E] are available for installation.
Always install the shoulder belts [Drift II and Drift III] crossing over to
prevent the shoulder belts from slipping off the shoulders during normal
wear as well as during an accident.
Risk of severe head injury or death during
rebound phase of frontal collision!
Separate TAKATA asm harness belts are supplied for the left and
right sides. Install harness belts on the correct side of vehicle.
Left and right belts are not interchangeable! Make sure asm-label is
on inboard strap.
2. Other anchor points
Self-drilled anchor points or anchor points to a roll cage or harness bar
must meet the following requirements to provide adequate performance:
a) Strength: > 14.7 kN [3300 ft-lb] each
b) Geometry:
Route shoulder belts symmetrically to seat centre line backwards.
Use of improper attachment points will impair system performance.
Inappropriate or weak tail strap anchor points will not withstand the
forces in an accident and increase the risk of personal injury or death
in an accident.
Never attach the tail straps/shoulder belts to anchorages intended for
the fixation of child seats (ISOFIX, LUAS, LATCH, UCSSS or CANFIX),
which are found on the filler panels behind the rear seats of some
passenger cars or the luggage area of some hatchbacks or station
wagons. These child seat anchor points are not strong enough to
withstand the forces of an accident and are not intended for adult
safety belts.
Harness belt systems may only be installed at suitable anchor points
for seat belt systems as originally installed by the vehicle
manufacturer.
For suitable anchor points for make, model and model year of your
vehicle, see Certified Vehicle List (Vehicle Reference List). If in
doubt, ask your dealer to show you where these.

Installation of Brackets
1. Stainless Steel Bolt-on Bracket Installation
Risk of severe injuries or death.
Repeated bending could weaken the bracket and cause it to fail
when loaded in an accident.
Make sure the webbing is not damaged during bracket bending or
the webbing may fail during an accident.
Never bend the bracket back and forth several times.
2. Snap-on bracket with eye bolt Installation
Assemble eye bolt and spring washer as shown
in the sketch. Bolt in eye bolt and tighten
securely. The optimum torque setting is 40 Nm
[30 ft-lb]. Pull either screw driver or similar tool
through eye and turn clockwise to tighten the
bolt securely.
Make sure the eye’s ring is pointing in direction
of pull (stress direction) as shown in the
following drawing.
This position will reduce the risk of unintended loosening of the eye bolt by
torque forces applied by the harness during racing. If you cannot achieve this
position by further tightening or loosening the bolt by a maximum of ¼ turn,
dismount the eye bolt and use 2 spring washers achieve the recommended
position.
Splint pin must be used!
3. Bending Procedure
Brackets which are restricted in alignment to the direction of pull
may be damaged or cut during an accident causing complete or
partial belt failure during an accident.
Severe injuries or death may occur.
4. Wrap [3-Bar Adjuster] systems for roll cage Installation
Risk of severe injuries or death.
Follow all instructions for Wrap Systems. Avoid slack in the system.
3-bar slides incorrectly wrapped or wrapped too far away from the
roll cage bar may allow webbing to slide during an accident. Slippage
or elongation will occur which may reduce the effectiveness of the
harness belt. Shoulder belts will give extra travel allowing possible
head and chest impact into the steering wheel.
The webbing must be wrapped tightly!
Never install a lap belt directly to a roll cage using the wrap around
technique.
1. Slide the webbing through slot 1 and 2 as shown
2. Make sure the strap end protrudes at least 100 mm [4“] or even longer
from slot 2. If it is less than 100 mm [4”] disassemble and start over again.
If longer, roll in the strap end and fix it by a cable tie to the shoulder belt.

3. Check again for proper shoulder belt tilt lock adjuster positioning and for the 3-
bar slide to be as close as possible to the roll cage bar or end bracket.
OPERATING
1. Basic adjustment
This harness belt model comes with adjusters on each side of the lap belt and
on the shoulder / tail straps. FIRST - adjust the lap belt portion so the push
button of the buckle is centred on the front of the occupant when the
harness restraint is worn.
2. Operation of tilt lock adjusters
To lengthen the restraint
Lift [tilt] adjuster to approximately
90° and pull in direction of the
arrowhead.
To tighten the restraint
Pull at adjustment strap end until
the correct tightness is achieved.
3. Fastening the harness restraint
a) place each arm and upper torso into the shoulder-lap belt loop and make
sure, the shoulder belts are running flat over the shoulders, collarbones
and chest
b) position each lap belt portion well into the bend between the upper thighs
and the pelvic crest. If this cannot be achieved due to short shoulder belts,
lengthen shoulder belts first
c) insert buckle tongue into buckle until you hear a distinct “click” indicating
the tongue is properly engaged
d) FIRST tighten lap belt, ALWAYS tighten lap belt first!
e) tighten shoulder straps. Both shoulder straps must be tightened equally.
Never pull to tight. Shoulder straps must not pull up the lap belt upwards
from the intended position. Tighten harness so shoulder / tail straps do not
sag behind the seat!
Lap belts which are too loose or not tightly positioned in the bend
between the upper thighs and the pelvic crest will result in
submarining during a frontal impact.
Shoulder belts which are improperly adjusted may allow head
impact, particularly in vehicles not equipped with frontal airbags.
Severe injuries or death may occur.
In case of a driver/co-driver change pre-adjust the harness restraint for a
proper fit to the different occupant.
Make sure the head rest is properly adjusted as well. Follow the procedures
from the car owner’s manual.
4. Releasing / Removing the harness restraint
a) Lengthen shoulder belts first by 50 mm to 100 mm [2”-4”] [not required in
case of accident or emergency]. This eases the exit from the harness but
also helps to properly position the lap belt when fastening the harness
restraint again.
b) Press red button on the buckle to eject the latch from the buckle.
Improper use of any harness belt can cause serious personal injury
or death.
To help reduce the risk of serious injury in an accident:
Never use the harness belt system for persons which weigh less
than 40 kg (88 lbs.) or those who are less than 150 cm (4‘11“) tall,
regardless of age.
Never strap more than one person in place with each harness
belt.
Never use the lap belt portion of the harness belt without the
shoulder belts and the anti-submarining strap (if a 5- or 6 point
belt is installed).
All straps must permanently run through the slots of the bucket
seat.
Always make sure that no strap is twisted when worn.
Always wear the lap belt portion of the harness system low and
tight across the pelvis.
Never wear the belts over heavy clothing as it can interfere with
proper positioning and adjustment of the belts, reducing the
overall effectiveness of the system.
Never wear the belts over rigid or breakable objects in or on your
clothing, such as eye glasses, pens, jewellery, keys etc. as these
may cause injury.
Never allow straps to rub against sharp objects.
Never allow the belts to be damaged by becoming caught in door
or seat hardware.
CARE and MAINTENANCE
1. Inspection
Check the safety belt once a month for any damage. Cuts, tears and other
damage to the belt will greatly reduce its effectiveness. Replace the belt or
damaged parts immediately with original spare parts (see page Spare Parts on
www.takataracing.com). Never use a damaged harness belt, use the standard
3-point belts which remain available for use.
Make sure the buckles are free of any obstruction and lock securely.

manufacturer!
2 In case of an accident
Risk of severe injuries or death.
Always replace a harness belt used during an accident. It is unfit for
further use. The belt may otherwise fail in subsequent accident.
Replace it immediately.
In TAKATA asm®models a partly or fully ripped open TAKATA asm®
system indicates the need for immediate replacement of the racing
harness.
FIA and other sanctioning bodies require that inspectors cut the
racing harness, or cut the labels off the racing harness, after an
accident.
Always inspect all anchorages for damages such as deformations or
cracks, after an accident.
Strictly follow the recommendations of the vehicle or roll cage
manufacturer if a repair should be necessary.
Re-use a harness belt that has been in an accident of any type cause
serious injuries or death.
After an accident, in addition to replacing seatbelts which were in use, also ask
your car dealer to carefully check all seatbelts attachment points for
deformation or cracks. Always make sure the car manufacturer’s guidelines
are followed if a repair is necessary.
