Install a roof-rack SS5 CrossLink lightbar

Fit the wind-deflector mounts, support the six- or seven-pod bar, route the matching harness and set the backlight.

Confirm the rack and prepare the parts

This is a rack-specific kit. A 2016–2023 Tacoma needs a compatible Prinsu or Sherpa rack already fitted; the truck model alone does not establish compatibility.

Rack / lightbar Required fit
Prinsu rack Wind deflector with a 40-inch lightbar cutout.
Sherpa rack Half-height wind deflector.
Six pods Rack width at least 41⅝ inches.
Seven pods Rack width at least 47⅞ inches.

Check the rack model, deflector and clearances before ordering. The supplied mounts keep the deflector in place after installation; it is temporarily removed and refitted during the mounting procedure.

The photos demonstrate the installation on a 4Runner roof rack; the bracket procedure applies to the compatible rack, including one fitted to a Tacoma. Use a T30 Torx driver for the Prinsu fasteners, 10mm and 13mm sockets, a 13mm wrench, a 5/32-inch Allen key and a tape measure. Have a second person help lift and centre the bar.

1. Remove the wind deflector

5. Assemble the CrossLink bar

Join the correct number of pods using the supplied CrossLinks and end mounts. Follow the instructions included with your bar and the linked CrossLink reference. The product specifies 5 ft-lb for the long-end bolts, with threadlocker; this value is not a torque specification for the rack fasteners.

6. Fit the support link mounts

For six pods, install one support-link mount on the centre CrossLink support. For seven pods, fit two mounts on the second and fifth CrossLink supports.

8. Centre and secure the bar

Centre the bar, then tighten the flange bolts with a 5/32-inch Allen key. Apply upward pressure so the CrossLink bracket sits against the wind-deflector panel before securing it.

9. Attach the support bracket

Slide the single T-nut into the top-forward channel of the rack’s first support crossbar. Attach the support bracket to the T-nut as shown. Repeat the required support arrangement for your bar.

16. Test and secure the wiring

Restore power as appropriate, check main-beam and backlight operation, then secure the wiring with the included zip ties. Recheck the mount, cable clearance and aim.

Lamp pins and whole-bar power are different concerns

The SS5 lamp connector uses red for main-beam power, black for ground and blue for backlight power. Use the complete kit’s matching fused relay and pod-connecting harnesses. Do not size a multi-pod bar circuit from a single-pod wire recommendation.

Choose a White-lens backlight colour

This procedure is for White-lens pods only. Yellow-lens pods have an Amber-only backlight. The setting never changes the main-beam colour.

  1. Start with backlight power off.
  2. Cycle the backlight on and off three times within three seconds, with each on action about one second apart.
  3. After the third cycle, continue at the same pace to scroll through White, Red, Blue, Green, Purple, Yellow, Amber and Teal.
  4. When the desired colour appears, leave the backlight on for five seconds to save it.
  5. Turn it off. The saved colour returns the next time backlight power is applied.

Synchronise White-lens backlights

  1. Enter programming with three on/off cycles at the same one-second pace.
  2. Continue through every colour twice—at least sixteen total power cycles.
  3. Once all colours have displayed twice, the connected lights reset to White.
  4. Leave the backlights on for five seconds to save, then select another colour if desired.
