Documentation¶

Parts Used¶

Rack System: - Gobi Toyota Land Cruiser 100 Stealth Rack (No Sunroof, 2 Cross Bars, Rear Ladder) - Model: LC100-STEALTH-4 - Product: https://gobiracks.com/product/gobi-toyota-landcruiser-100-stealth-rack-4/

Storage: - 2x Roam 95L Rugged Case - Product: https://www.roamadventureco.com/products/95l-the-rugged-case - Total capacity: 190L waterproof storage

Lighting: - Rigid Industries Adapt 40" LED Light Bar (SKU 240413) - Product: https://www.rigidindustries.com/adapt-40-240413.html - Power: 30A circuit (Interior Fuse Block Circuit 5) - 2x Rigid Industries Ignite Spot Pod (SKU 20511) - Product: https://www.rigidindustries.com/ignite-spot-black-surface-mount-20511.html - Power: 20A each (Engine Bay SPOD 1 Circuits 1-2)

Communication: - Starlink Mini Roof Mount (custom) - Power: 10A circuit (Interior SPOD Circuit 5)

Wiring Requirements¶

Rigid Adapt 40": Power from Interior Fuse Block → roof penetration → front of rack
Rigid Ignite Pods (2x): Power from Engine Bay SPOD 1 → roof penetration → sides of rack
Starlink Mini: Power + Ethernet from Interior SPOD → roof penetration → center of rack
All roof penetrations require waterproof grommets and proper sealing
Wire gauge: 10 AWG for 30A circuit, 12 AWG for 20A circuits (see wire gauge chart)

Installation Notes¶

Gobi rack mounts to factory roof rails
Roof penetrations must be planned carefully to avoid leaks (headliner routing)
Consider running all wiring through a single penetration point if possible
Use marine-grade heat shrink and waterproof connectors for all roof connections
Test all lights before final rack installation
Load capacity: Verify Gobi specs for max static/dynamic load with cases

Date Completed: [In Progress]¶

Cost: $[TBD - track as installed]¶

Notes:¶

Wiring is pending - see ELECTRICAL_CIRCUITS.md for complete routing plan
Roof penetration location needs to be determined (recommend A-pillar area)
Consider installing wire loom/conduit for clean routing inside headliner
Starlink mount may need custom fabrication or adapter for Gobi cross bars

Electrical Modifications¶

Status: 📋 Planned¶

Modifications Overview¶

Dual battery system with Redarc charger (installed)
2x BantamX units mounted on PowerTray (installed)
"Big 3" electrical upgrade (alternator, battery, ground)
Engine Bay SPOD 1 - Lighting & Ambience (8 circuits, 100A) - using BantamX units
Engine Bay SPOD 2 - Driving, Recovery & Utility (8 circuits, 100-150A) - using BantamX units
Interior SPOD - Power, Communications & Gear (8 circuits, 100A)
Interior Fuse Block - Switched/Always-On Power (8 circuits, 60A)
Interior MSD Relay Block - High-current switching (4 relays)

System Architecture¶

Engine Bay SPOD 1 (Lighting & Ambience): 1. Roof Floodlights - Right (20A) 2. Roof Floodlights - Left (20A) 3. Roof Floodlights - Rear (20A) 4. Roof Chase Light (10A) 5. Rock Lights (10A) 6. Exterior Courtesy Lights (10A) 7. Halos (5A) 8. Projector Backlighting (5A)

Engine Bay SPOD 2 (Driving, Recovery & Utility): 1. Round Bumper Lights - Adapt mode (30A) 2. Round Bumper Lights - All On (30A) 3. Amber Fog Lights (15A) 4. White Fog Lights (15A) 5. Reverse Lights (10A) 6. Winch Relay control (5A) 7. Air Compressor (30A) 8. [Spare Slot]

Interior SPOD (Power, Comms & Gear): 1. Interior Ambient Lights (5A) 2. Ham Radio 1 (10A) 3. Ham Radio 2 - Power Pole (10A) 4. 400W Inverter (15A) 5. Roof Power for Starlink (10A) 6-8. [Spare Slots]

Interior Fuse Block: 1. Front Driver Seat Power (15-20A) 2. Front Passenger Seat Power (15-20A) 3. Rear Seat Heater - Right (10-15A) 4. Rear Seat Heater - Left (10-15A) 5. Roof Light Bar - Rigid Adapt 40" (30A) 6-8. [Spare Slots]

Wire Routing Strategy¶

Critical Junction: "Behind 2nd Row" - Most wire runs converge at this location - Engine bay connections to interior - Overhead console connections - Door-mounted circuits - Seat heater controls - Communication equipment routing

Major Cable Runs: - Engine bay → Interior (firewall grommet) - Roof penetrations (headliner routes) - Door-mounted circuits (4 doors) - Center console power/controls - Rear antenna/bumper connections
