Getting Started

Thank you for choosing Ecoological. This guide covers the roof visor when it is equipped with three center spotlights and two outer surface-mount pill-style chase / warning lights.
Complete almost all wiring on a workbench before the visor goes on the truck. Mounting is the last step.
This kit does not include wiring, fuses, or switches. Buy those separately. This is an example of a typical install, not a complete technical manual — change routing and switch locations as needed, but keep the light functions below.


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

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.

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.
• Digital Multimeter or Test Light: To verify 12V power sources.
• 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 Pill Light Power (Main Run): ~20 ft of 16 AWG (Red).
  For Grounding: ~10 ft of 12 or 14 AWG (Black).
• Signal/Control Wire (Standard Gauge):
  For Pattern Select (Run to Dash): ~20 ft of 18 AWG (Yellow).
  For Synchronization (Visor Jumper): ~2 ft of 18 AWG (Yellow). Connects the two outer pill lights together.
• Fuses & Holders:
  1x In-line Fuse Holder with 5A Fuse (for Pill Lights).
  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 Pill Light Main Power. 1x Momentary Push-Button Switch – For Pill Light Pattern Select.

Do not use an On/Off toggle for the yellow pattern-select wire. The yellow wire must only receive power when the momentary button is pressed.
Pill Light Wire Colors

• RED: Main power (+12V)
• BLACK: Ground
• YELLOW: Synchronization and pattern select
• WHITE: Not used. Cap and insulate each white wire separately. Do not connect the two white wires together.

These pill lights do not use a master/slave setup. Connecting the yellow wires together keeps both lights synchronized.
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 Pill Lights) 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.

1. 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.
2. Wire the Pill Lights (2):

• Main Power: Connect the RED wires from both outer lights together. Attach your 16 AWG main power wire here.
• Synchronization / Pattern Select: 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. Attach your long 18 AWG yellow pattern-select wire to this same connection. The yellow wires stay connected together so both lights remain synchronized and change patterns at the same time.
• White Wires: The WHITE wires are not used. Cap and insulate each white wire separately. Do not connect the two white wires together.

1. Loom & Secure: You should now have one bundle of wires (The "Harness") exiting the visor (Ground, Spot Power, Pill Light Power, Pattern Select). 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. Remove paint, rust, and dirt from the contact area so you have a clean metal-to-metal connection.

Phase 3: Final Connections
Connect the wires from your visor harness to your switches/power sources:
Spotlights
Battery positive → 20A fuse → Spotlight On/Off switch → 12 AWG spotlight power wire.
Pill Light Main Power
Battery positive → 5A fuse → Pill Light On/Off switch → 16 AWG red wire leading to both pill lights.
Install the 5A fuse as close to the power source as practical.
Pill Light Pattern Select
Use a normally open momentary push-button switch.

• Connect one terminal of the momentary switch to the switched +12V output of the pill light main power switch.
• Connect the other terminal of the momentary switch to the long YELLOW wire leading to the joined yellow wires on both pill lights.

The pattern switch must be connected after the main power switch. This keeps the pattern-select circuit from receiving power unless the pill lights are turned on. When the button is pressed, it temporarily applies switched +12V to the joined yellow wires.
Do not use an On/Off toggle switch for the yellow pattern-select circuit. The yellow wire must not remain continuously connected to positive power.

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

1. Reconnect the battery.
2. Check Spotlights: Turn on the spotlight switch. All 3 center lights should come on.
3. Check Pill Lights: Turn on Pill Light Main Power. Both outer lights should begin flashing in their currently stored pattern.
4. Check Sync: Press and release the momentary button. Both pill lights should advance to the next flash pattern at the same time.
5. Reset to Pattern 1: Press and hold the momentary button for approximately five seconds, then release it.
6. Confirm that both WHITE wires on the pill lights remain separately capped and insulated.

If the two outer lights are not synchronized, verify that both yellow wires are permanently connected together, both lights are receiving the same switched +12V power, and both black wires have a secure ground.

Phase 5: 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.
