Install a Tacoma Stealth lightbar

Check the kit and prepare

This guide covers the 2016–2023 Tacoma factory bumper using the Diode Dynamics Stealth kit. The vehicle mounting procedure covers Classic and current SS30 kits; their lightbar wiring and features differ. Match the connector and supplied harness to your actual kit.

Have a 10 mm socket and wrench, 12 mm socket, trim tool and a cutting tool if you plan to trim the air deflectors. A second person helps position and aim the bar. Work with the engine off and the vehicle secured; disconnect power while making electrical connections.

1. Release the upper grille

Remove the two upper grille bolts with a 10 mm socket, then release the two push clips.

2. Remove the grille

Pull straight forward to release the remaining clips; set the grille aside safely.

3. Release the air deflectors

Remove one push clip from each air deflector behind the grille.

4. Remove the air deflectors

Rotate each deflector inward and pull it out.

5. Remove the crash-bar nuts

Remove two nuts per side with a 12 mm socket.

6. Fit the driver-side bracket loosely

Position the bracket on the crash bar and loosely refit its nuts. Leave it adjustable.

7. Position the lightbar

Feed the bar through the passenger-side fog-light opening with its harness toward the driver side. Lower it, then slide it toward the passenger side until centred.

8. Fit the passenger-side bracket

Place the passenger-side bracket and loosely start its nuts.

9. Attach the lightbar

Use the supplied hardware at the upper mounting holes. Keep the assembly loose for alignment; have another person support the bar.

10. Torque and aim

Tighten the crash-bar nuts to 43 ft-lb. Set the vertical aim, then tighten the lightbar mounting hardware with a 10 mm wrench. This torque is for the crash-bar nuts, not every bolt.

11. Route the pigtail

Bring the lightbar pigtail behind the headlight and up into the engine bay.

12. Trim the air deflectors if refitting

Optional: trim the deflectors as shown. The removed lower portions are not reused.

13. Refit the trimmed deflectors

If you chose to trim and reuse them, reinstall the retained deflectors in reverse removal order.

14. Connect the harness

Connect the matching lightbar and power harness. Route toward the battery, using the factory firewall grommet where needed for switch wiring. Follow the wiring section for the current SS30 Standard system.

15. Refit and inspect the grille

Reinstall the grille, clips and upper bolts. Check cable clearance, operation and aim before use.

Current SS30 Standard wiring

The new SS30 has a DTP connector on a lead from the side of the bar. Use the matched high-current harness. Locate the relay near the battery; connect the red input to battery positive and black to battery negative or a suitable factory ground.

The yellow trigger wire on that auxiliary pigtail is not a universal colour code for every lamp wire. Follow the diagram supplied with your exact harness. Keep cables away from heat and moving parts, protect firewall passages and secure connections.

These Standard kits have a fixed main-beam colour and an amber backlight. No SmartSelect programming is required. Classic bars use their own matching harness and do not gain the new bar’s backlight circuit.

For a custom circuit, have the wire gauge, fuse and switch/relay capacity sized for the actual bar current and cable length. Sport is 120 W and Pro is 165 W; do not choose a harness from a lower-power pod example.

SS30 reference dimensions and hardware

The universal bracket diagram is a component reference, not a replacement for the Tacoma mounting sequence. Classic dimensions and hardware differ.
