How to Install the KOSMOS LED Kit in Your PG Gundam Exia

Step-by-step guide covering all 4 zones, drive belt routing, App pairing, and troubleshooting — for both mid-build and completed models.

KOSMOS PG Exia LED Kit — the GN Drive Belt zone activates the translucent cable system built into the PG skeleton

⚠️ Before You Start

The KOSMOS LED kit is designed for installation during the build process — specifically at the skeleton stage, before external armor panels are attached. Installing mid-build is significantly easier than retrofitting a completed model.

If your PG Exia is already complete, you'll need to disassemble the relevant armor sections before accessing the LED positions. This guide covers both scenarios, with mid-build as the primary workflow.

What's in the Box

• ▸ LED components for all 4 zones (GN Drive / Head & Eyes / GN Capacitors / GN Drive Belt)
• ▸ Main controller board
• ▸ Infrared remote control
• ▸ Wiring harness
• ▸ Exclusive Exia metal nameplate

Tools Recommended

• Fine-tip tweezers (for LED placement in tight spaces)
• Plastic-safe masking tape (for temporarily securing wiring during test phases)
• USB-C power source or charged battery (for testing before armor-up)
• KOSMOS Universe App — download before starting (iOS App Store / Google Play)

The GN Drive LED unit is the first component to install because all other wiring routes away from it.

1. With the torso skeleton partially assembled (GN Drive bay accessible), locate the Zone 1 LED mounting position in the upper chest/back cavity
2. Seat the Zone 1 LED unit into the pre-formed mounting position — shaped to fit the GN Drive bay exactly
3. Route the lead wire along the interior cable channel toward the lower torso (where the controller will be positioned)
4. Secure the wire loosely with masking tape — do not finalize routing until all zones are installed

Note: Position the LED so it faces outward through the translucent GN Drive component — this produces the glow visible through both chest and back armor.

This is the most time-intensive stage and the one that most defines the finished effect. The drive belt runs through the skeletal structure from the torso outward along each limb.

1. Before assembling the arm and leg skeletons, lay the drive belt LED strips into the translucent cable housing channels built into the skeletal frame
2. The strips follow the physical path of the translucent cable elements — they are integrated into the visible structure, not hidden behind it
3. Route connecting wires back along the interior of each limb skeleton toward the torso
4. Do not fully close limb skeleton panels until drive belt routing is confirmed in Stage 5

Key tip: Work one limb at a time. Complete one arm's drive belt routing, verify the wire reaches the torso connection point, then move to the next limb.

The GN Capacitors are the cluster nodes at the shoulder, knee, and wrist positions — visible termination points of the drive belt system.

1. At each capacitor position, insert the Zone 3 LED components into the pre-formed mounting points in the skeleton
2. The capacitor LEDs connect to the drive belt zone wiring — follow the labeled connectors in the harness
3. Route any remaining wire back toward the central controller channel

Note: The shoulder capacitors are the most visible position on the finished model. Verify these are securely seated — loose placement will create uneven lighting across the shoulder area.

1. With the head skeleton assembled but not yet covered, install the Zone 2 LED unit into the eye/sensor position in the head assembly
2. The eye LED unit is designed to fit the monocular camera housing precisely
3. Route the lead wire down through the neck joint channel into the upper torso
4. Test fitting: partially close the head to verify the LED sits flush and the lens component is properly illuminated

Note: This is the smallest LED component in the kit. Use fine-tip tweezers for placement.

Before attaching any external armor, test all four zones.

1. Connect all four zone wiring leads to the main controller board — leads are labeled by zone, match them to the corresponding ports
2. Connect USB-C power or battery to the controller
3. Power on using the included remote
4. Verify each zone illuminates: cycle through zones individually using the remote to confirm all four are functional
5. Check drive belt continuity: all translucent cable sections should glow evenly. Uneven glow indicates a strip is not fully seated in the channel
6. Test articulation: gently move each joint and verify no wiring is catching or pulling

With all zones confirmed, proceed with standard armor panel attachment. Key consideration: wiring management.

• At each joint, leave a small loop of wire slack inside the joint structure — this prevents wire tension when the joint is articulated
• The lower torso / hip area houses the main controller — the PG Exia's rear waist section is designed to accept this
• Run the USB-C or battery connection to an accessible location — the rear waist, designed for a display stand connection, also accommodates the power cable

1. Download the KOSMOS Universe App (iOS or Android)
2. Power on the controller via the remote
3. In the app, select "Add Device" and follow the Bluetooth pairing prompt
4. Once paired, all four zones appear as independently controllable channels
