Safety:
PLEASE READ BEFORE INSTALLING HEATING ELEMENT ASSEMBLIES!
Do not modify this product.
Do not connect this product to factory seat heater parts
Check Corporation wire heating element assemblies are specific to each seat and are not to
be cut. They are designed to fit specific vehicle seats according to the model and production
year of the vehicle. For a full list of vehicles that your kit is compatible with, please call
customer service at 877-607-8941.
 Some front passenger seats are outfitted with occupant detection sensors which are not
compatible with any after-market seat heater. Consult with Check Corporation to determine
the appropriate heating element assembly for each specific vehicle.
 Heating elements should NEVER be installed onto foam where an occupant detection
sensor is visible on the Top surface of the foam, even if the heating element would not touch
the sensor. Heating elements are to be placed onto foam bun only. The heating elements
may adversely affect or cause the sensors or airbag system to not function correctly, thereby
causing severe injury or death.
 The heating elements must be connected to switched or keyed ignition power only, to
prevent battery drain when vehicle is off.
 Check and determine that the heating elements will fit under the seat trim covers in the
desired areas. The listing channels or the Velcro hold-downs should line up with the cutouts in
the heating elements. This is not important if the heating elements do not cross over a listing
channel or Velcro hold-down. See figure 1
 BONDED SEATS (UPHOLSTERY GLUED TO FOAM BUN)
Never remove the cover of a bonded seat. The cover of a bonded seat cannot be installed
again once it has been removed. If installation of a heating element assembly is to be
attempted in this kind of seat, cut an opening in the foam bun large enough for the element to
fit ½″underneath the cover. A professional should only attempt this, as mistakes often result in
the replacement of the seat foam and cover.
 CLOTH UPHOLSTERY
If your upholstery is thin, and does not have at least 1/4” of foam sewn onto the backside of the
upholstery, it is recommended that you apply a 1/4” to 1/2” thick layer of foam or headliner
fabric to the entire insert area between the heating element and the upholstery. This will
eliminate read-through and make sure the temperature is at an appropriate level.

Page 8 Installation Instructions
IF THESE SAFETY CONDITIONS CANNOT BE MET, DO NOT ATTEMPT INSTALLATION
To prevent OVERHEATING AND/OR A FIRE follow these instructions carefully:
 Remove paper adhesive liner from the cushion and back heating elements before
installing them onto the foam bun. This is mandatory as the heating pattern is
maintained by the adhesion of the heating elements to the foam bun of the seat. If the
heating elements are not secured they could develop hot spots.
 The paper liner is combustible and is not intended to be installed with the heating
elements.
 The Heating elements must NOT be folded into seat listing channels except where
cutouts were designed into the element. Do not fold the heating elements against
themselves.
 Cushion and back heating elements are wired to operate in series only. Do not change
the wiring to power the heating elements in parallel.
IN THE EVENT THAT THESE WARNINGS ARE DISREGARDED, THE CUSTOMER
SUPPORT AND WARRANTY BECOMES NULL AND VOID. MISUSE OF THIS PRODUCT
MAY CAUSE SERIOUS INJURY TO PERSON OR PROPERTY.

Installation
1. Pre-wire all components on your workbench and test with a multi-meter
for continuity. Do NOT use a battery charger as a power source. Use a 12V D.C.
power source. If there are any problems, see the troubleshooting page. IF THE
KIT HAS A CUSHION AND BACK HEATING ELEMENT THEN BOTH MUST BE
USED. NEVER OPERATE CUSHION OR BACK ELEMENT SEPARATELY.
SINGLE ELEMENT HEATERS AVAILABLE IF NEEDED.
2. Locate vehicle fuse panel and determine routing of power harness.
Each seat heater needs a separate 7.5A inline fuse (included) with a switched
ignition 12V power source.
3. Install the ground wire ring terminal, from the power harness, to the fuse
box ground screw. Clean terminals and grounding point of paint, grease, and dirt to
ensure a good electrical connection. NEVER DRILL THROUGH THE FLOOR.
4. Disconnect and isolate the negative (ground) battery cable.
5. Discharge latent electricity - pump the brakes a few times, and wait five
minutes for the system to discharge. It is important to do this before disconnecting
any airbag connectors.
6. Remove Seat(s) from vehicle. Care should be taken, as the sharp
edges of the seat frame will scratch the interior trim. Use duct tape or padding to
cover sharp areas before removing seat.
7. Remove the seat covers and verify that the heating elements fit.
HEATING ELEMENT ASSEMBLIES SHOULD NEVER BE INSTALLED ONTO
FOAM WHERE AN OCCUPANT DETECTION SENSOR IS VISIBLE ON THE TOP
SURFACE OF THE FOAM. EVEN IF THE HEATING ELEMENT WOULD NOT
TOUCH THE SENSOR.
8. Determine a location for mounting the switch. Cut a hole
according to the dimensions shown in the wiring diagram. Connect switch harness
to the back of the switch as shown in the wiring diagram (by wire color).
9. Locate area for heating elements by tracing element outline onto
foam bun. Be sure that the cushion element is placed on the cushion bun, and that
the back element is placed on the back bun.

Page 10 Installation Instructions
10.Remove the adhesive release paper. This paper must be removed, as IT
WILL BURN.
11.Attach the heating elements to the foam bun (not the seat cover) by pushing
down on the pads causing the adhesive to stick completely to the foam bun. NOTE:
Element may be hard to handle if you tear the release paper off all at once. Paper can be
peeled away in increments as you apply the element to the foam bun. Apply cushion
element rear to front and back element bottom to top. RELEASE PAPER MUST BE
COMPLETELY REMOVED. FAILING TO COMPLETELY REMOVE PAPER IS A FIRE
HAZARD AND NULLIFIES AND VOIDS WARRANTY.
12.Re-install seat trim covers. Do not install hog rings through the heating
element. THE SEAT LISTING WIRES SHOULD NOT LIE DIRECTLY ON TOP OF THE
HEATING ELEMENTS. IF THE LISTING WIRES MUST CROSS THE PADS IN THE
CHANNELS, ADD SOME FOAM FOR PROTECTION.
13.Install the seat into the vehicle
14.Reconnect airbag connectors
15.Reconnect the ground of the battery
16.Connect the extension harnesses to the controller as shown in the wiring
diagram.
17.Mate all remaining connectors (as shown in the wiring diagram). SECURE
THE WIRE WITH THE TIES PROVIDED. CHECK THAT THE RECLINING OF THE
SEATS, OR THE MOVEMENT OF THE SEAT FRAME DOES NOT PULL, FRAY, OR
CUT THE WIRES
18.
TEST SEAT FUNCTIONS; RECLINE, FORWARD, REVERSE, UP, DOWN,
ETC. ENSURING THAT NO STRAIN IS PLACED ON ANY OF THE SYSTEM’S WIRES.
Ensure all of the anchor bolts are tight to the manufacturer’s specification.
Using the Seat Heater for the First Time (before you deliver to your customer)
OPERATION OF THE HEATED SEATS:
After turning the system on high setting, you must sit in the seat and should be able to feel
heat within 1-5 minutes depending on the thickness of the trim cover material over the
element.
The thicker the trim cover, the longer it takes to feel the heat.

Figure 2: Automotive seat
1. General Seat Construction
A typical automotive seat will have a seat cover (cloth or leather), base foam and a frame.
Typically, j-clips connect the seat cover to the seat frame (see Figure 2). When the j-clips
are unfastened, the seat will still be connected to the base foam through the listing
channel. The following are some examples of methods used to secure the seat cover in
the listing channel. A) plastic bar w/ hog rings B) metal rod w/ hog rings C) Velcro ™ D)
clips (see Figure 3).

3. Cutting your carbon fiber heating elements
 DO NOT make any cuts within 4.75 inches from the entire edge (wire harness edge)
 DO NOT make vertical cuts
 You can shorten the entire heating element
 You can make horizontal cuts between the buss bars

Page 14 Installation Instructions
4. Mark opening across a trench. The minimum distance from edge of element to opening is
40mm (1 9/16”). Tuck pad into seam as shown.
5. Cut out opening. Cover borders of cutout with tape trips provided on heating element if any
electrical conductive part is used in the channel, such as hog-ring or metal bar. If Velcro or
plastic clip used in the channel, then the boarders don’t need to be covered.
6. Peel off paper adhesive liner prior to installation. Push down on the pads causing the
adhesive to stick completely to the foam bun.

Troubleshooting the heating elements
 Set the multi-meter to ohms. For a cushion element, touch the red and black probes
to the red and yellow pins. For a back element, touch the red and black probes to
the red and black pins. The meter should show that there is continuity through the
wires. A normal reading for either a cushion element or a back element is
approximately 5.0 to 7.0 ohm’s without any cutout in the element; 1 cutout of 2.5”
will increase the resistance to approximately 6.0-8.0 ohm’s; 2 cutouts of 2.5” will
increase the resistance to approximately 7.3-10.0 ohm’s. if the meter reads an open
(Mega ohm’s), there is a break in the circuit.
 A test light will NOT work to test the continuity

Page 16 Installation Instructions
Using fuse-taps
If you are using fuse taps, it is important to draw from the
correct side of the fuse
When connecting the red wire on the power
harness
connect it to the cold side of the fuse.
Red = Cold Side
Using Optional Add-A-Fuse Accessory (Purchased Separately)
This adaptor is rated to handle up to 10 amps on the accessory fuse.
Prong indicated in photo below must go to the DC +12V hot side of the fuse
receptacle. In the example photo, the 7.5 amp fuse runs the seat heater
accessory; the 10 amp fuse is the original amperage fuse from the fuse box.
The 7.5 amp fuse is in line with the red wire for connection to the DC +12V seat
heater wire.

Troubleshooting of the electrical system
If the system does not heat up, check the following:
To test the unit you must sit in it for at least a 5-minute period in which the heat has
time to reach the seat surface.
 Check the fuse utilized during the installation.
 Ensure that all connections are properly mated and that the 12V DC and
ground wires are properly installed. (See seat heater wiring diagram)
 A break in the heating element circuit. To check for this, pull on the wires at all
connectors to verify they are properly seated in the connector. Don’t forget the
connector on the back element. Also check for continuity at the 4 pin connector. The
cushion and back elements must be connected and use a multi-meter set to ohms.
See Figure 1
 A low voltage condition on the controller input from the fuse box. To verify the
voltage input, use a multi-meter set to volts, across red AND black wires at controller
module (it should read 11-15V).
If the heating elements, switch, and seat harness test OK, then a power problem
exists, check the following:
 Using a multi-meter or a test light, start at the power connection and trace back
through all of the connectors and the switch to determine where the power loss is
occurring. Repair as necessary.
If the fuse continues to fail, check the following:
 Each pair of heating elements that are installed in the vehicle must have their
own fuse.
 A poor ground connection. Check connections or try another grounding point.
Another possible cause is the fuse used for power is computer controlled (try another
fuse location).
