Install the compressor assembly onto the lower master cylinder stud and the two firewall studs with the previously installed Grimm OffRoad spacer.

Wrangler and Gladiator models will use different mounting bracket holes for the lower master cylinder stud.

The extra bolt holes provided in the top of the compressor bracket allow mounting of an ARB Manifold (Part # 171503), allowing the connection of multiple air lockers to a single compressor. Additional wiring is required.

Reinstall the OE nuts onto the firewall studs to secure the bottom of the Grimm OffRoad compressor mounting bracket. There is not much clearance, you will need to pull the compressor bracket away from the firewall about 1/4” to get the nuts on. Tighten with 10mm wrench.

Torque to 8 lb-ft [11 Nm].

Reinstall the lower master cylinder nut.

Torque to 13 lb-ft [18 Nm].

The ARB Twin Compressor comes with two wire harnesses. The large gauge harness with the fuse blocks is the main power harness and will be used to power the compressor. The other harness is the control harness and is replaced by the included Grimm OffRoad control harness.

Plug the supplied Grimm OffRoad wire harness into the smaller of the two ARB Air Compressor plugs.

Plug the ARB power harness into the matching plug on the ARB compressor, route the wire up over the brake booster, along the firewall to the battery. Use zip ties to anchor the wire harness along the firewall. Connecting the power terminals will be covered later.

Install the supplied filter relocation hoses onto the barb fittings on the compressor. The longer of the two hoses connect to the innermost fitting, the shorter connects to the outer fitting.

These lines simply press-on and do not need any additional clamps.

Route the air hoses up between the brake booster and the inner fender structure.

Install the 1/4” NPT x JIC4 90° elbow into the back of the bulkhead fitting on the controls plate using a 14mm wrench. Use thread sealant on the NPT threads and match the alignment of the fitting to the picture.

Install the ARB Compressor Filters on to the leg of the controls plate as shown.

Thread the two 90 degree female 1/4” NPT x barb fittings onto the ARB filter nipples and tighten by hand. Match the alignment of the barbed fittings as shown in picture above.

The ARB filter housing is plastic; the threads can strip out easily. DO NOT OVER-TIGHTEN!

This step pertains to the 2.0L eTorque engine only. Skip to Step 13 if you have any other engine.

The 2.0L eTorque engine has a mini fuse/relay box that needs to be relocated to make room for the Grimm OffRoad Controls Panel.

Remove the painted fender bolt and both bolts securing the fuse/relay box with a 10mm wrench/socket.

Relocate the fuse/relay box up above the brake booster and secure with the existing flanged nut and the M6 x 1.0 included flange nut.

Use a 10mm socket/wrench to torque hardware to 7 lb-ft [9 Nm].

The fuse/relay box mounting bracket may need to be bent down slightly to prevent any interference with the hood when closed.

Proceed to Step 13 and finish mounting the Grimm OffRoad Controls Panel.

The clip on the fender holding the washer line needs to be flipped upsidedown, to the other side of the bracket as shown.

The 3.6 V6 engine needs to have a wiring harness moved before installing the controls plate.

Using a 14mm wrench, install one end of the included Stainless Steel Pressure Hose on to the previously installed fitting on the compressor.

Install the other end of the included Stainless Steel Pressure Hose on to the brass bulkhead fitting on the Controls Plate.

The Stainless Steel Pressure Hose uses flared fittings and does not need any type of thread sealant.

Install 1/4" NPT male air chuck of preference (not included, we recommend ARB hose kit # ARB171302 which includes the ARB0740112 NPT air chuck). Make sure to use thread sealant on the NPT threads.

Place the sPOD gasket down first, then the Module, and tighten the mounting screws with a #2 phillips screwdriver.

Connect the power wires to the sPOD module, noting that the circuit breaker is installed at the battery end. Use a 3/8" socket or wrench to tighten.

To finish the install, connect the ARB compressor harness power leads directly to the battery according to the ARB Twin Compressor Installation Guide.

Three 6 gauge M8 stud size ring terminals are needed to connect the ARB Twin Compressor Harness to the battery terminal ends. M8 ring terminal ends are required and do not come with the ARB compressor harness.

Connect the sPOD leads directly to the battery according to the sPOD Installation Guide.

Run the compressor wire harness up through the gasket and connect to switch number of choice on the sPOD module. Black wire to GND, purple wire to SW.

Install the sPOD control panel in the Jeep, and install the control wire from the control panel to the module.

Connect any other accessories to the sPOD module.

After the sPOD install has been completed, turn on the compressor using the sPOD control panel.

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

Check to make sure there are no air leaks at any of the fittings.

Make sure to turn off the compressor when not in use.
