How to Install 2014-2019 5th Gen Toyota 4Runner Stealth Lightbar Kit | Diode Dynamics. Video loads only when selected.

1. Remove the upper trim panel

Push the centres down and remove the thirteen push rivets holding the core-support trim. Reset each rivet by pushing its centre back through the top.

2. Release the top of the grille

Remove the six additional plastic push rivets shown. Remove the centre screw with a 10 mm socket.

3. Disconnect the factory fog lamps

Remove the six screws across the underside of the bumper with a 10 mm socket. Reach underneath and disconnect the fog-lamp connectors.

4. Remove the wheel-well screws

Remove the three screws securing the bumper edge inside each wheel well.

5. Release the bumper corners

Use a trim tool to release the upper snap. Slide the lower screw clips off the bumper and carefully pull the corner away from the fender. Repeat on the other side.

6. Lift the bumper away

With a second person supporting it, pull the bumper straight forward to release the remaining snaps around the headlights. Set it down safely.

7. Release the air-dam rivets

Remove the two plastic air-dam push rivets shown. Leave the air dams in place.

8. Loosen the bracket mounting bolt

Use a 14 mm wrench to loosen the bumper-bar bolt identified in the photo: the second bolt in from the outer end.

9. Slide the brackets into position

Pass each bracket’s open slot beneath the air dam and under the loosened bolt.

10. Loosely secure the air-dam mount

Fit the supplied M6 screw, washer and nut to the air-dam mounting point. Leave the adjustment loose for now.

11. Install one or two bars

Use the supplied flanged M6 hardware to mount the SS30 bars. For two bars, the guide suggests the first and sixth, or first and seventh, slots from the top. Tighten the mounting hardware after aligning the assembly.

Wiring diagram

12. Locate the relay

Choose a secure relay mounting point near the battery or main power terminal. Use the fused harness supplied with the selected package.

13. Connect power and ground

Connect the red power lead to battery positive or the main positive terminal. Connect black to battery negative or a factory grounding point. All power sources must be fused.

14. Choose the switch arrangement

For a compatible auxiliary switch, unplug the switch lead at the white connector, insert the supplied pigtail and crimp its yellow wire to the auxiliary-switch lead. This lead controls the relay; lamp power comes from the battery. If no suitable switch bank is fitted, use the included toggle-switch adapter.

15. Connect the lightbars

Route the output wires clear of heat and moving parts, then connect them to the bars.

16. Check bumper clearance

Loosely refit the bumper before final assembly. If it touches a bar, move that bar farther rearward in the slots and recheck.

17. Reassemble and test

Reverse the bumper-removal sequence. Reconnect the factory lights and confirm the auxiliary lights operate as intended before use.
