2018+ Jeep Wrangler JL/JLU & Gladiator JT 4XE Charge Port Air Chuck Conversion Kit Part Number 10593

Verify that all parts shown in the pictures are present.

Remove the plug from the center of the Charge Port housing and the tether attaching it.

The center of the charge port housing needs to be cut out to allow installation of the bulkhead bracket assembly and switch. Take your time trimming and just cut a little at a time. It doesn't have to be perfect, but you don't want to cut too much. You can always trim more later if needed.

Cut as shown with a sharp box knife or something similar.

The base plate will cover the section that was cut out, and make sure enough material was removed for the air coupling and switch holes to be clear.

A new mounting hole needs to be added to the lower left of the Charge Port Housing.

Use one of the provided M5x0.8 screws and nuts to secure the base plate via the right upper hole.

Using the Base Plate as a template, drill the new hole with a 1/4" drill bit.

The Bulkhead Bracket Assembly should come with the brass bulkhead fitting pre-installed.

Install the 1/4” NPT x JIC4 90° fitting into the back of the bulkhead fitting as shown using a 9/16" socket/wrench. Make sure the fitting is pointed down. Use thread sealant on the NPT threads.

Note that NPT fittings are tapered fittings and must not be overtightened. If you can't get the fittings to point the correct direction, it is recommended to remove, use a couple additional wraps of Teflon tape, then reinstall.

Note that a 1" open end wrench can be used on the opposite side to prevent the bulkhead fitting from spinning while installing the NPT fitting.

The air hose coupling can be installed into the bulkhead fitting at this time. We recommend using ARB's 0740112 Air Hose Coupling which is included in their 171302 Pump Up Kit.

With the Base Plate lined up on the front of the Charge Port Housing, align the Bulkhead Bracket Assembly on the back.

Insert the five M5x0.8 16mm Hex Drive Button Cap Screws through the Base Plate from the front and secure with the M5x0.8 Flanged Nylocks on the back.

Torque with a T25 Torx Driver and 8mm socket/wrench to 35 lb-in [4 Nm] (Note, this is pounds per inch, not foot! Don't overtighten!)

The assembly should look as shown.

Confirm the orientation of the JIC4 Fitting.

Push the ARB switch into the bracket until you hear it snap into place.

Be absolutely sure that you hook up this switch correctly according to the diagram in the first image. If wired incorrectly, you can short power directly to ground and damage the wiring in the compressor itself. ARB will not warranty your compressor if this happens.

Plug the wires from the Grimm OffRoad supplied switch wire harness into the back of the ARB compressor switch. The BLACK wire goes to the top terminal, the RED wire goes to the center terminal and the PURPLE wire goes to the lower terminal.

Attach the Stainless Steel Pressure Hose to the installed NPT fitting on the Bulkhead Bracket Assembly.

The Stainless Steel Pressure Hose uses flared fittings and thread sealant is not required.

Using a T40 torx driver remove the 4 bolts holding the cowl trim piece on the driver side.

Lift out and remove.

Install new provided left side Cowl Trim Panel.

Reinstall and torque all cowl trim hardware with a T40 Torx Driver to 10 lb-ft [13 Nm].

Route the wire harness and air hose from the Charge Port Housing Assembly through the Cowl Trim Panel and into the engine bay.

The Charge Port Housing Assembly will snap into place in the Cowl Trim Panel.

Connect the wire harness and air hose to the ARB Twin Compressor mounted with the GOR10013 Compressor Mounting Kit in your engine compartment.

If using a different ARB Twin Compressor mounting solution, a longer air hose may be needed and the included wire harness may need to be extended.

Toggle the compressor switch to the on position. The compressor should turn on for a short period of time then turn off.

The fan on the ARB Twin Compressor will continue to run until the switch is turned off.
