FORD BRONCO REAR CARGO COMPRESSOR MOUNT 2021+ Ford Bronco (4 door) Hard Top Only — Install Guide

Important Notes

Prior to beginning this installation, read these instructions and the compressor manufacturer's instructions to familiarize yourself with the required steps.

Electrical Note: Power wires will need to be run from the Bronco's battery or switch system back to the cargo compartment. Considering the distance of the wire run, for the Twin ARB we recommend 6 AWG for the ground and 8 AWG for the power. Reference the ARB Installation Guide, as Desert Does It is not a wiring expert.

Step 1 — Prepare the Vehicle

1. Park the vehicle on a level surface.
2. Set the parking brake.
3. Disconnect the battery terminals.
4. Reference the compressor installation instructions for wiring the compressor.

Step 2 — Remove the Trim Panel

1. Locate and remove the plastic trim panel on the passenger side underneath the roll bar.
2. This panel covers the soft-top mounting holes and should be removable by hand.
3. If necessary, use a small plastic pry tool to remove it.

Step 3 — Attach the Trim Cover

1. Using the two small stainless steel Flat Head bolts, attach the Desert Does It trim cover (13" x 2" plate) to the backside of the Desert Does It main plate.
2. Align the two small threaded holes on the edge of the trim cover with the corresponding countersunk holes on the main plate.
3. Position the trim cover with the DDI logo facing up.

Step 4 — Install the Spacers

1. Attach the spacers to the threaded holes where the soft top would be located.
2. Each spacer is different, so make sure each spacer is installed in the correct location.
3. The spacers are marked 1, 2, and 3:
   • #1 — Front Top: Medium length, 2.3" long
   • #2 — Back Top: Longest, 2.5" long
   • #3 — Bottom: Shortest, 1.75" long
4. Slide the appropriate bolt through the spacer.
5. Remove the backing from the adhesive tape.
6. Thread the bolt a couple of turns into the correct mounting location.
7. Slide the spacer against the body and press firmly so the spacer adheres securely.
8. Once the spacer is secure, remove the bolt.

Step 5 — Install the Bulkhead Fitting

1. Using thread seal tape, attach the Bulkhead Fitting to the Compressor Plate.
2. Using thread seal tape, attach one of the 90-degree fittings to the backside of the Bulkhead Fitting.
3. Attach the 1/4" airline to the fitting.

Step 6 — Install the Compressor Fitting

1. Using thread seal tape, attach the 90-degree fitting to the compressor.

Step 7 — Attach the Compressor Plate

1. Use the three provided bolts to attach the Compressor Plate to the three spacers.
2. Feed the wiring harness and airline through the open slot in the Compressor Plate.
3. Tighten the bolts securely.

Step 8 — Connect the Compressor

1. With the help of another person, lift the air compressor into position.
2. Connect the wiring harness and airline.
3. Cut the airline to the desired length.
4. Once connected, push any excess wiring and airline back inside the Compressor Plate.
5. Using the four provided Security Bolts and security bit driver, attach the compressor to the corresponding mounting holes on the mounting plate.

Step 9 — Mounting a Single ARB Compressor

1. Reference the ARB instructions and rotate the compressor head until it is horizontal and as low as possible.
2. On the Desert Does It Compressor Mount, use the four threaded holes for mounting the Single ARB compressor.
3. Using the provided hardware, bolt through the ARB bracket into the Desert Does It Compressor Mount.

Step 9 — Mounting a Twin ARB Compressor

1. On the Desert Does It Compressor Mount, use the four top through-holes to attach the ARB compressor.
2. Use the four provided Security Bolts and washers.
3. Install the bolts from the backside of the plate.
4. If desired, rotate the air outlet port on the compressor for additional clearance. Reference the ARB instructions for Orientating the Compressor Outlet.
5. For maximum clearance, rotate the outlet port toward the bottom of the compressor and feed the air hose underneath the compressor.

Step 10 — Optional Fitting Kit

1. Install one 90-degree 1/4 NPT fitting into the compressor.
2. Install the Bulkhead Fitting through the Desert Does It Compressor Mount.
3. Install the remaining 90-degree 1/4 NPT fitting into the Bulkhead Fitting.
4. Cut the airline to the desired length and install it into each push-to-connect fitting.
5. Be careful not to kink the airline.

Step 11 — Wire the Compressor

1. Wire the compressor according to the directions provided by the compressor manufacturer.

Step 12 — Installation Complete

Enjoy your onboard air!
