SEAT HEATER KIT
AUTHR2000
Introduction
Your new Autoloc® seat heater kit can
transform nearly any automobile, boat,
truck, or RV seat into a comfortable throne
of warmth. No longer will cold weather be
so uncomfortable. Installation of the
AUTHR2000 Seat Heater Kit can be
performed with the simplest of household
tools by even the ‘weekend’ mechanic in
the seats of your choice for use with any
12 volt system capable of supplying 10
amps continuously. Please read the
following notes before beginning
installation.
• All instructions MUST be followed closely. Inability to do so will void warranty and could
cause damage to seats, vehicle or people.
• The width of the heating elements must not be changed by cutting or folding. Seats must have
a minimum of 11 inches of width between bolsters.
• The wiring harness must allow for full range of motion of the vehicle’s seat adjustment and
must not intrude with either driver or passenger leg & foot space.
• Great care must be taken on cars with side airbags. Only attach heating element to center of
seat, and NEVER connect power to any airbag connections during seat heater installation.
• Only wiring harnesses and components that came with the AUTHR2000 should be used. Do
not substitute any parts.
• Before installation in your seat, connect power to seat heater elements for 45 minutes to
allow for material outgassing. A slight odor will be noticeable, and may be noticeable for the
first few times the heaters are used after installation. This is normal and will subside.

Installation
Remove entirely from the vehicle the seat in which the AUTHR2000 will be installed after you
have disconnected the negative battery cable. Make sure your work space is free of debris
or obstructions and remove the outer seat cover from your vehicle’s seat, exposing the foam
padding underneath.
Separate bottom seat cushion from seat back at the seat’s hinge (the point at which it
reclines). Remove and dispose of all upholstery clips and unhook all other connections
using a screwdriver or other tool depending on your particular seat. Make sure there is no
loose metal parts and clean the foam of any debris.
Lay the AUTHR2000 seat heating elements on the bottom seat cushion and on the seat back
to check for placement with the label side facing up. Make sure that there is a minimum of
11” of space between the seat side bolsters, as the heating elements must not be fitted into
any channels running from front to back on the seat. See illustration below for fitment sample.
The electrical supply wires can be fitted into the back so they are not seen in the finished
seat. Fit the heating element into any channels without folding any of the areas covered by
adhesive tape- only the 1” wide textile edge can be folded into lateral (front to back, top
to bottom) channels. Areas with adhesive tape must be adhered to a flat surface. Only the
length is variable and in most cases it is not necessary to cut the heater element.

The heating element will be
shortened (lengthwise) to fit within
the seat back, which gets narrow
towards the back. Shown as
example, your seats may differ.

In order to enable the seat’s cover to be re-installed on the seat, holes must be cut into the
heating element, BUT NOT ON THE ADHESIVE.
Lay the heating element onto the seat and use a light marker to mark where the channel will be
under the heating element. Remove the heating element and lay it on a flat surface. Between the
adhesive sides, cut out 1 to 5 evenly spaced holes about 1” in diameter according to locations
in which the seat’s cover will attach through the channel to the seat’s frame.
5.
Now that you have your circles cut, cover the front and back of the holes with the enclosed
adhesive tape, and then punch holes 1/2” in diameter in the center of the original holes. This
way, the heating element is completely enclosed in tape and secure from touching any metal on
the seat’s frame.
Repeat this process for the seat bottom cushion as well if it also has horizontal channels.
5a.
Now lay the heating element back on the seat foam, this time with the printed side facing the
foam. Remove the backing on the adhesive and fully adhere the element to the foam. The
connection wire can be run through a convenient slot you make in the foam that prevents it from
interfering with the various seat joints.
6.
Re-assemble the seat and fit the seat cushion cover back onto the seat itself. Do not use any
metal fasteners or upholstery clips to re-attach it. Use the enclosed cable ties. Be sure to not
crush any of the wires, and make sure that in the process of re-attaching the cover you do not
create any folds in the heating element.
7.
If your seats have no horizontal channels, skip to step six.

While routing the wire harness, be sure that it will not be pinched, squeezed, chafed or in any
other way compromised. Attach it to the seat frame securely in a way that allows for normal
seat operation and adjustment. Re-install the seat into the vehicle and plug the open connectors
of the harness into the open wires on the heating element.
8.
Run the wire harness to the dashboard, center console or side seat shield (if your seats have
one) and cut a 20mm hole where you want the seat heater activation switch to live. Pull the wire
out of the hole, plug into the switch, and then push the switch into the hole securely.
9.
Connect the remaining open wires to your vehicle’s 12v electrical system. Refer to your vehicle’s
wiring diagram to find a 12v source that is capable of handling a 10-amp continuous source
that will only work when the ignition/accessory is on to prevent the seats from draining your
battery when you leave the vehicle if you forget and leave them on. The seats consume about 70
watts per seat, which would drain the battery considerably without the engine running.
10.
Start your vehicle’s engine and turn on the seat heaters. Make sure there are no abnormally hot
spots or overheating due to folded heating elements. Now, enjoy your toasty seats!
