Question 1

Does the seat heater harness kit work with all years of the LX470 / 100 Series?

Accepted Answer

Not all years use the same floor harness connector. 2002 is a split year, meaning two different connector configurations were used during production. For any 2002, we need a photo of the floor harness connector to determine which version you have.

Question 2

Does the LX470 vs. the Toyota Land Cruiser 100 Series matter for fitment?

Accepted Answer

Yes. The LX470 came with powered seat position from the factory, which the Land Cruiser 100 Series did not. This difference affects the under-seat wiring configuration, so it is important to specify which vehicle you have when ordering.

Question 3

Is there a seat position sensor that affects airbag function?

Accepted Answer

Some years have a hall effect sensor on the driver seat rail. It connects via two wires to a black plug and runs from the floor to the sensor along the rail. Its function is to shut off the driver airbag when the seat is pushed all the way forward. If your truck has this sensor, we need photos of it to confirm we have the correct mounting plate. The passenger side does not have this sensor because the passenger occupant detection is handled separately by the pressure pad under the seat cushion.

Question 4

What does the driver proximity sensor do, and does it carry over?

Accepted Answer

The driver proximity sensor shuts off the airbag if the driver seat gets too close to the steering wheel. The entire gray harness on the driver side from the floor to the seat gets reused as-is, including this sensor and the seat belt buckle. Nothing needs to be cut or modified on that harness. The passenger side does not have this sensor. More info:

Question 5

What connectors are under the seats on a 2006 LX470?

Accepted Answer

On each side you will find a cream-color 10-pin connector, a gray 5-pin connector, and a 2-pin yellow connector. The 10-pin carries power to the seat motors and the seat heaters. The 5-pin connects to the seat belt buckle and the driver proximity sensor. The yellow connector is for the airbag..

Question 6

Is the 10-pin connector not available through Toyota or the aftermarket?

Accepted Answer

No. The 10-pin connector is not available through the aftermarket, the Japanese OEM manufacturer, or from Toyota directly. Only a few of its pins are actually needed for the new seat heaters. We handle this by using the seat-side portion of the connector sent in by the customer.

Question 7

For my 2006 Land Cruiser what exactly do you need from my existing harness?

Accepted Answer

We only need the 10-pin connector from the seat side, plus as much of those two small wires as you can get to. The yellow connector and the 5-pin gray connector are not cut for any reason. The entire gray harness from the floor through the proximity sensor and seat belt buckle is reused whole.

Question 8

Do I reuse my existing seat belt buckles?

Accepted Answer

Yes. The seat belt buckles and their harnesses are connected to the seat, and they carry over to the new seat.

Question 9

What is the passenger seat pressure sensor and why does it matter?

Accepted Answer

The pressure sensor is a printed circuit board encased in plastic, glued to the seat foam just under the leather. It tells the vehicle's airbag system when someone is in the passenger seat. There is no aftermarket replacement for this sensor in Toyota's system, so it must be removed from your factory seat and installed into the new scheel-mann seat.

Question 10

How is the passenger pressure sensor removed?

Accepted Answer

The sensor pad, its harness, and its connector all need to come out together. In practice, customers have been able to remove it without destroying the seat. We work with you on the process and can coordinate installation into the new seat before it ships.

Question 11

Are the scheel-mann seats motorized like the factory LX470 seats?

Accepted Answer

No. All position adjustments on the scheel-mann seats are fully manual. The motors in your 100 Series are internal and integral to the factory seat, and they do not carry over. The new seats adjust manually for fore/aft position and seatback angle, and lumbar support.

Question 12

Can the new seats use my existing seat heater switches on the center console?

Accepted Answer

Yes, that is the goal. Once we receive and process the 10-pin connector from your existing seat, we build the integration harness that allows your factory heater switches to control the heating function in the new scheel-mann seats.

Question 13

What is the Klima option and how is it controlled since I don't have factory seat cooling?

Accepted Answer

Klima is scheel-mann's seat ventilation (cooling) system. It is controlled through round switches included with the seat harness. One switch handles heating; one handles the Klima fan. Both run off a dedicated harness that requires a chassis ground and an ignition-switched 12V source so the fans cannot be left on and drain the battery.

Question 14

Where can the Klima switch be mounted?

Accepted Answer

There are a few options. One approach is drilling a hole in the center console near the existing seat heater switches, though there is a module directly behind that panel that limits depth. The area on the front left of the center console where the A/C Heat (ACH) switches used to be is another good candidate if that mount is available in your truck. Instagram user ben3dbuild specializes in 100 Series interior 3D scanning and fabrication and may have a blank panel for that area that can be drilled. Tolerance Stack also has its own switch mount solution available coming soon.

Question 15

Can't the motor power wires from the factory seat be reused to power the Klima fan?

Accepted Answer

No. Those wires are not ignition-switched, meaning they are always live and could drain the battery if the fans or heaters are left on. They could be converted to ignition-hot by adding a relay with a switch, but that is work done on the owner's end. The simpler approach is tapping into an existing ignition-switched circuit such as the 12V plug inside the center console. The Klima harness terminates in two bare wires: a red for ignition-hot and a black for ground.

Question 16

Does scheel-mann offer a color that matches the tan/ivory interior of the LX470?

Accepted Answer

The closest available option is the creme-beige, which is a built-to-order color sourced directly from Germany and is not stocked in the US. Lead time from Germany is typically a 12-14 weeks. Swatches of stocking colors are available on request. The grey cloth stocking option ships in approximately 3-5 business days from US inventory.

Question 17

Will the creme-beige match my aged factory leather perfectly?

Accepted Answer

Not perfectly. Factory leather on a 20-year-old vehicle dulls and darkens over time, so any new leather will appear brighter by comparison. scheel-mann also notes that lighter leather colors show wear faster and are more susceptible to dye transfer from dark clothing such as denim. They will build to your specification, but want customers to understand what to expect.

Question 18

Is the upholstery material available to purchase separately for other interior work?

Accepted Answer

Yes. The fabrics and leatherettes used in the scheel-mann seats are available by the yard. The grey cloth ships from Portland. Creme and other built-to-order materials ship from Germany or the Netherlands. See tolerance-stack.com/upholstery2 for the full selection.

Question 19

Can I use a custom leather color that is not in the core stocking range?

Accepted Answer

Yes. There is an expanded color selection available with an automotive-specific coating applied. Colors outside the core range do not carry the same durability guarantee as the stocking colors, though customers have used them without reported issues. We make this known upfront so you can make an informed choice.

Question 20

Where exactly is the passenger pressure pad located in the seat foam?

Accepted Answer

Placement can vary somewhat by seat. It's generally described as glued to the seat foam just under the leather, but at least one real-world teardown found the pad sitting in the middle of the foam rather than directly between the foam and leather.
Because of this variation, plan to feel/inspect carefully during removal rather than assuming a single fixed depth.

Question 21

Do JDM (Japan-market) 100 Series Land Cruisers use the same brackets as US-spec ones?

Accepted Answer

Not confirmed. The seat mounting feet appear to be the same despite JDM VX100 seats being different from US-spec 100 Series seats, but this hasn't been verified on an actual JDM vehicle.
No JDM 100 Series is currently known to be running these brackets, so treat this as unverified until confirmed on a real JDM truck.
