Prior to any work being done, it is recommended to use collision tape or some other protective cover in area where
work will be done to minimize possibility of damage. Vipers are very compact vehicles, drivers compartment
especially. Working in the driver’s compartment area requires patience, special skills and tools.
STEP 1. Removing factory seat from car:
Slide the seat forward as far as possible and adjust the seatback forward as far
as possible. You will now have access to the electrical plug. Disconnect the plug then, remove aft nuts on the seat track.
STEP 2.
Remove the seat belt buckle from the side of the seat using a T50 male torx. Do not discard the buckle, it will be
used later.
STEP 3. Installing the floor harness mount (TKOSROD1289K):
You must remove the white sound deadening that is
under that carpet. As well as the sound deadening around the factory retractable seat belt area. YOU DO NOT HAVE TO
REMOVE THE CARPET COMPLETELTY TO DO THIS. Simply pull the carpet up, reach under and pull out the white
sound deadening. The sound deadening is glued in and should pull away from the underside of the carpet. Removing the
sound deadening allows better clearance when installing the lap belt mounting.
STEP 4.
At this time, you can install the shoulder belt harness. Behind the driver and passenger seats, you will see a
plastic cover on the back firewall approximately at driver or passenger shoulder height. Remove this cover and you will
see either two eyelets or metal eyes bolted down to the rear firewall upper crossmember. Remove the eyelets and/or the
metal eyes, as you will not need these for the installation of the shoulder harnesses. Now, install the red 2-bolt, ¼ inch
thick metal plate that was in your installation kit. The red ¼ inch metal plate is installed first and spaces off the firewall
crossmember. The red 2-bolt, ¼ inch thick spacer is installed so the shoulder harnesses don’t bind up and cause undo
wear. Use the 7/16 bolts included in your kit with Loctite blue 242 to install shoulder the harnesses.
STEP 5.
Now that you have removed the sound deadening (see STEP 3) and installed the shoulder harnesses (see STEP
4), you can now install the lap belt and sub harnesses onto the harness floor mount. Doing this on a bench outside of the
vehicle is much easier. Use the bolts and lock washers provided in the harness floor mount hardware kit.
STEP 6.
Now, install the factory seat back in car.
THIS IS JUST A TEST FITMENT SO YOU DO NOT HAVE TO
FINAL TORQUE ANY FASTENERS AT THIS TIME
. Now install the harness floor mount bracket. Make sure the
factory seat is fully forward so that you can gain access. With the harness floor mount installed temporarily, the harness
floor mount is equipped with (2) extra mounting holes that will require (2) .375” dia holes to be drilled. (2) holes are
located at rear of the harness floor mount; this is where you will drill through. With the seat installed in the vehicle and
the front mounting factory seat mount bolts snug, you can now drill the (2) 375” holes through floor pan (it will be
necessary to have access to the underbelly of the car to correctly install. ACR model Vipers: make sure to remove the
front bolts on the diffuser belly pan and pull away from the belly of the vehicle prior to drilling mounting holes. ACR
models require some clearance on the diffuser belly pan so that the secondary mounting bolts and washers can be
installed.)
