Getting Started

Thank you for choosing Ecoological. This guide walks you through the wiring and installation of your roof visor’s integrated lighting system.
Installation Strategy: To save time and ensure clean connections, you will perform the majority of the wiring on a workbench ("Bench Prep") before the visor is mounted to the vehicle. The final step will be securing the visor to the roof.

PLEASE REFER TO THE WIRING DIAGRAMS BELOW TO GUIDE YOUR CONSTRUCTION OF WIRING HARNESSES AND WIRING CONNECTIONS

Required Tools & Materials​

1. Required Tools & Materials:
Please Note: This kit does not include wiring, fuses, or switches. You must purchase these separately to match your specific vehicle configuration. Also note the following guide is intended solely as an example of a typical installation and does not constitute a complete technical manual. Customers should alter these steps as necessary to fit their specific vehicle, equipment, and preferences
Tools Required

• Wire Strippers & Crimpers: For cutting and securing wire connections.

• Heat Gun: For sealing heat-shrink connectors.
• Socket Wrench Set: For battery disconnection.
• Drill & Stepped Drill Bit: Required if you are installing aftermarket switches.
• Trim Removal Tools: To safely route wires behind the headliner and A-pillar.
• Zip Ties: To secure the wire loom.

Materials Needed (Purchase Separately)

• Primary Power Wire (Thicker Gauge):
  • For Spotlights (Main Run): ~20 ft of 12 AWG (Red or Green). Crucial for handling the 20A load.
  • For Flasher Power (Main Run): ~20 ft of 14 or 16 AWG (Red).
  • For Grounding: ~10 ft of 12 or 14 AWG (Black).
• Signal/Control Wire (Standard Gauge):
  • For Takedown & Pattern (Runs to Dash): ~20 ft each of 18 AWG (Blue (optional for takedown function), White).
  • For Synchronization (Visor Jumper): ~2 ft of 18 AWG (Yellow). Connects the two outer lights together.
• Fuses & Holders:
  • 1x In-line Fuse Holder with 5A Fuse (for HG2 Flashers).
  • 1x In-line Fuse Holder with 20A Fuse (for Spotlights).
• Switches:
  • Option A (Factory Aux Switches): Use if your Tacoma is equipped.
  • Option B (Aftermarket Switches):
    • 1x Toggle/Rocker Switch (On/Off) – For Spotlights (Must be rated for 20A or use a relay).
    • 1x Toggle/Rocker Switch (On/Off) – For HG2 Main Power.
    • 1x Toggle/Rocker Switch (On/Off) – For HG2 Takedowns.
    • 1x Momentary Push-Button Switch – For HG2 Pattern Select.

Step-by-Step Installation​

Phase 1: Bench Assembly (Wiring the Visor)Perform these steps with the visor placed on a stable workbench. Do not mount it to the truck yet.

1. Install Lights: Secure all 5 lights (3 Center Spotlights, 2 Outer Flashers) into the visor shell.
2. Create Common Ground:
   • Locate the thin BLACK wires from ALL 5 lights.
   • Splice them together into your single 12-14 AWG BLACK wire.
   • Leave this main ground wire long enough (~10 ft) to reach a chassis ground point on the truck later.
3. Wire the Spotlights (3):
   • Connect the RED wires from the three center spotlights together.
   • Attach your 12 AWG (Green/Red) main power wire to this bundle.
4. Wire the Flashers (2):
   • Main Power: Connect the RED wires from both outer lights together. Attach your 14/16 AWG main power wire here.
   • Takedowns: Connect the BLUE wires from both outer lights together. Attach your 18 AWG Takedown signal wire here.
   • Synchronization: Connect the YELLOW wire from the Driver side light directly to the YELLOW wire from the Passenger side light using the short 2 ft jumper. This wire stays in the visor and does not go to the truck.
   • Pattern Select: Attach your 18 AWG White signal wire to the WHITE wire of the Passenger light (Master). Cap off the white wire on the Driver side; it is not used.
5. Loom & Secure: You should now have one bundle of wires (The "Harness") exiting the visor (Ground, Spot Power, Flasher Power, Takedown, Pattern). Wrap these in wire loom/tape for protection. (You may choose to use either a black tape to match the windshield, or a body colored tape to make the wire more incognito.
   
   

Phase 2: Vehicle Routing & Switch Prep

1. Disconnect Battery: Remove the negative (-) terminal.
2. Install Switches: Mount your aftermarket switches in the cab (or identify your factory Aux switches).
3. Run the Harness:
   • Position the visor temporarily on the roof to check wire length (do not bolt down yet).
   • Route the harness you created in Phase 1 down the windshield channel or through the roof (depending on your specific install preference) and into the dashboard area.
   • Run the BLACK Ground wire to a solid metal bolt on the chassis/frame.

Phase 3: Final Connections
​Connect the wires from your visor harness to your switches/power sources:

​Phase 4: System TestTest the system BEFORE permanently mounting the visor to ensure all crimps are solid.

1. Reconnect the battery.
2. Check Spotlights: Turn on; ensure all 3 center lights fire.
3. Check Flashers: Turn on Main Power. Driver side should flash 2x (Master), Passenger side 1x (Slave).
4. Check Sync: Press the Momentary button. Ensure both flashers change patterns simultaneously.
5. Check Takedowns: Toggle the Takedown switch. Flashers should go solid white.

Final Mounting

1.) Dry-fit your Roof Visor by following the instructions below without removing the backing to the 3M double-sided tape. Ensure the part is centered and make note of its positioning for reference later. This will give you the opportunity to practice the installation without permanently installing the overlay on the truck. Centering this part during the dry fit is an essential step to know where you want to position your part before installing, do not skip this step.

​2.)  Ensure the roof is clean and free of debris where the 3m tape will be touching down. Use Isopropyl rubbing alcohol to free the surface of any chemicals or soap residue that may limit the effectiveness of the 3M tape.   

3.) Apply the adhesion promoter to the areas of the roof where the 3M tape will be touching down. (Read the instructions on the adhesion promoter tube to learn how to begin the flow of adhesion promoter.)

​4.) Before it is time to install the overlay, we must address the red backing tape. For all exterior/outside pieces of 3m, take the edges of tape and peel them back 1" to the front of the visor, securing them in place with masking tape. This will ensure we have access to the tape when we install them on the top. For the four interior strips, peel the backing tape completely off the part. Refer to the picture below for clarification.
​*Only If you have it* If you have protective film, peel back the edges about 1" for easy access to peel off post installation.​

5.) Position your Visor over the area of the roof you want to house it on before applying any pressure. Once you're in position, begin applying pressure to one side of the overlay and slowly continue with that pressure down the rest of the Visor. ​

6.) Remove the masking tape securing the 3m tape in place. Peel back the 3m tape from the visor on all remaining 3m pieces of tape. Apply pressure to the part as you remove the tape from one side to the other. 

*Only if you have it.* After all 3m tape is removed and pressure applied, remove the protective film from your visor.

7.) Wait 48 hours before taking your vehicle through automated car washes or driving on the highway.  Reapply pressure to all taped areas 24 hours after the initial installation.

Care for your Shellz™

Most Shellz colors will function much like paint.  They can be buffed, polished, taken through automated car washes, and whatever else you would normally do.  Some ABS colors can be sanded down and re-painted if ever you decide you want to change colors.  The only color that cannot be polished, and re-painted is the Textured Black TPO.
