TOYOTA TUNDRA UNDERSEAT COMPRESSOR MOUNT (2007-2021 Tundra) — Install Guide

Important Notes

• Prior to beginning this or any installation, read these instructions to familiarize yourself with the required steps and evaluate whether you are experienced and capable of performing these modifications.
• A factory service manual for the air compressor and vehicle should be used in conjunction with these installation instructions.
• WARNING: The seat weight sensor is extremely sensitive. Handle the seat very carefully. Do not drop the seat or sit in the seat while it is on the floor. If the sensor is damaged, replace the unit. Failure to do so may result in personal injury or death.

Step 1 — Prepare the Vehicle

1. Park the vehicle on a level surface.
2. Set the parking brake.
3. Disconnect the battery terminals.

Step 2 — Remove the Seat

1. On the driver seat, remove the plastic trim pieces to access the front and rear seat base bolts.
2. Remove all four factory seat base bolts using a 14mm socket.

Step 3 — Disconnect the Seat Wiring

1. Lift the front of the seat to gain access to the seat wiring.
2. Unclip and disconnect any wiring between the vehicle and the seat.
3. To gain access to the factory wire harness, either lift the front of the seat or remove the seat from the vehicle and place it upside down on a clean work surface.

Step 4 — Reroute the Factory Wire Harness

1. Using a small flathead screwdriver or small trim removal tool, remove all wire harness plugs from their mounts. See the installation photos with red square highlights.
2. Reroute the harnesses and reinstall the plugs on top of the seat rail. The plugs were previously installed on the bottom of the rail.

Step 5 — Mount the Compressor

1. Mount the compressor to the Desert Does It Under Seat Compressor Mount using the supplied stainless-steel hardware.

IMPORTANT — Twin ARB Compressor:
The Twin ARB compressor allows the outlet port to be rotated to best suit the installation position. For maximum clearance, rotate the outlet port toward the bottom of the compressor and route the air hose underneath the compressor. The outlet port is the tallest part of the compressor, so rotating it as low as possible provides the most clearance.

1. On the Desert Does It Compressor Mount, use the holes marked "B".
2. Using the provided hardware, bolt from the underside of the Desert Does It Compressor Mount through the compressor brackets.

Step 6 — Install the Compressor Mount

1. Place the assembled compressor mount into the vehicle.
2. Line up the mounting holes with the front and rear seat mounting locations.

Step 7 — Wire the Compressor

1. Wire the compressor according to the directions provided with the compressor.
2. Reroute the wires so they are free and clear of any hazards.

Step 8 — Reinstall the Seat

1. Place the seat back into the vehicle.
2. Reconnect all seat wiring.
3. Use the provided zip ties to secure all wires so they do not droop below the harness plugs.

Step 9 — Check Seat Movement

1. With the seat bolts snugged, confirm the seat has full movement.
2. The Twin ARB compressor may limit forward seat movement by approximately 3/4".
3. If necessary, remove the seat and correct any clearance or movement issues.

Step 10 — Final Torque

1. Torque all seat mounting bolts to 27ft-lbs or German Spec (good 'n tight).
2. Reconnect the battery.

Final Check

• Verify all seat mounting bolts are properly installed and torqued.
• Confirm all seat wiring is securely connected and routed away from hazards.
• Confirm the compressor and mount are securely fastened.
• Confirm the seat has the required range of movement.
• Confirm the battery is reconnected.
