First: Disconnect The Ground Cable

Disconnect the negative ground cable from the battery before you begin. This cuts power to the vehicle's electrical system, preventing accidental shorts and protecting the wiring, seat belt sensors, and safety systems you will be working around.

Seat Belt Anchors and Spacers: Orientation and Placement

Each anchor and spacer carries a label specific to your application, noting where it mounts: Door Side or Inboard, and Driver Side or Passenger Side. Anchors shaped like a hockey stick mount with the tab pointing down. Anchors shaped like a U mount with the tabs pointing up.

Place the Anchors Under the Seat

Set each anchor between the underside of the seat and the sliding rails, with the tab pointing down as shown. Fasten the seat belt component to the anchor using the new bolts supplied in your kit.

Installing the Sliding Rails onto the Seat

The release handle has a slight bend. Lay it on a flat surface and you will see light beneath one side, as shown. When installing, orient the handle so the bend points away from the seat.

Release Handle Orientation

Note the slight bend in the handle. When installed, it curves downward, away from the bottom of the seat.

Lay Out the Rails and Release Handle

Before mounting, arrange both rails and the release handle as shown, following the arrow marked UP. Confirming the orientation now ensures each rail goes onto the seat correctly and the handle's bend faces away from the seat.

Mount both rails to the seat

The correct holes are reinforced with a second layer of steel as shown in the picture. (Note: there are three mounting holes on each rail and the hole in the middle does not have an extra layer of steel).

Begin With the Rear Mounting Bolt

Using the 5mm Allen wrench, start with the rear mounting bolt, along with its lock washer, from the hardware supplied with your seat. Thread it in and tighten most of the way, leaving it slightly loose. This gives you room to start the front mounting bolt.

Release the Slide to Reach the Front Mounting Holes

Gently slip a wide flat blade screwdriver between the seat and the release tab, then twist it to release the slide. This opens access to the front mounting hole. Install the front bolt and tighten it fully. 

Next, slide the rail forward, install the remaining rear bolt, and fully tighten both rear bolts. 

Once all six bolts are installed, torque each one to 18.4 lb-ft (25 Nm).

Install the Release Handle

With the rails bolted to the seat, flex the release handle slightly and guide it into position. The handle offers two sets of mounting holes. Either will work, with one set allowing the handle to extend farther out under your legs. Line up your chosen hole with the single tab sticking out of the slide on one side. Once in position, tap the handle with a soft mallet or small hammer to seat it fully into the slider.

Seat the Release Handle in the Groove

Using a soft mallet or small hammer, tap the handle gently until it sits fully in the groove of the slider. A fully seated handle should feel solid and release the slide smoothly.

Attach the Adapter Brackets to the Sliding Rails

Use the supplied hardware to attach the adapter bracket to the sliding rails. The bracket style depends on your vehicle.

On vans, the adapter is a pair of riser brackets. Mount them to the sliding rails before moving the seat into the vehicle, then use the factory bolts to attach the risers to the seat base.

On most cars and trucks, the adapter is a large plate with feet at the corners. It is easier to install the plate in the vehicle first, using the factory bolts to attach it to the floor, and then move the seat and sliding rails into position.

For every application, start all four bolts and leave them loose until each one is threaded. Once all four are started, tighten everything down. Finish by bolting the seat belt to the seat using the supplied bolts.

Connecting to Factory Seat Heating

If your vehicle has factory seat heating, you can run the seat heaters from the original factory switch. Identify the hot and ground wires in the factory seat heat connector, and confirm them against your vehicle's wiring diagram before connecting. Our seat harness uses a red wire for hot and a black wire for ground. Splice the factory connector onto the seat harness, matching hot to hot and ground to ground, then plug it into the factory wiring.

Note: On some vehicles, the seat heat controls run through the CAN bus system. Rather than switching power directly, the factory switch sends a digital message to a control module, which then powers the heaters. Because of this, the factory connector may not supply the simple 12-volt power and ground the seat heaters need. In these cases, the scheel-mann seat heat switches should be wired as a standalone system. This is outlined in the next step.

Allow Slack and Secure the Wiring

The driver's side seat includes a seat belt sensor wire, in addition to any seat heat wiring. For both, leave the wiring loose and long at first. Slide the seat through its full range of travel, and swivel it if applicable, watching closely to confirm the wiring between the seat and the seat mount or floor never pulls tight. Once you are sure the length is adequate, use zip ties to support the wiring high enough that it cannot catch on the sliding rails as the seat moves back and forth.

Locate the Armrest Mounting Points

The armrest mounts on the inboard side of the seat. If your seat was custom ordered with leather and an armrest, the factory will have cut holes in the upholstery at the mounting bolt locations, circled in red here. 

If the seat does not have an integrated seat belt, use the short bolts supplied with the armrest. The long bolts are for seats with an integrated seat belt.

Find the Mounting Bolts on Seats Without Precut Holes

If your seat does not have precut holes, press along the upholstery on the inboard side of the seat. You will feel two bolts beneath the material. The location is highlighted here.

Cut a Small Cross to Reach the Bolts

Using a razor blade or X-Acto knife, make a small cross-shaped incision in the upholstery directly over each bolt location. Keep the cuts as small as possible, just large enough to access the bolts beneath.

Trim the Tabs to Expose the Bolts

Fold back the corners of each incision, then use a pair of snips to trim off the tabs. This clears the opening so you have full access to the bolts beneath.

Remove the Upper Bolt and Prepare the Arm Rest Bolts

Find the black oxide coated countersunk bolts included with your arm rest. These new bolts will be used to mount the arm rest. Then, using a 6mm Allen wrench, remove just the upper original bolt, leaving the lower bolt in place for now.

Install the Arm Rest One Bolt at a Time

With the original upper bolt removed, position the arm rest and start a new black bolt in the upper hole. Once it is started, remove the original lower bolt and start the second new black bolt. These bolts secure the seat back to the reclining mechanism, so never remove both at the same time. If a new bolt does not thread in easily, look into the bolt hole to confirm everything is properly aligned. Once both bolts are started, tighten them fully.

Torque the Arm Rest Bolts

With the arm rest installed, confirm both bolts are fully tightened to 35.4 lb-ft (48 Nm).
