5V regulator
Converts the vehicle’s 12V supply to the 5V required by these LEDs. Use the regulator specified for your kit.
INSTALLATION GUIDES / INTERIOR LIGHTING
Flow Series Dash Trim Installation Guide
Install your Lighting Trendz Flow Series interior dash trim lights with wiring references, fitting and cutting tips, and setup instructions for your controller.
How do you install Flow Series dash trim lights?
Connect the 5V regulator, the correct Flow Series controller, and the trim strips. Test every strip, plan the wire routes, then fit the strips into the interior trim gaps and cut the free ends to length. Finish by setting up the app or remote for your controller.
Identify your controller first: standard Bluetooth/SP105E and handheld controllers use the 4-output harness layout. Bluetooth Pro uses its own controller-output layout and the MotoAuto app.

1. Parts & Preparation
The base dash trim kit uses four 43-inch strips. Additional strips and footwell lighting depend on your selected options. Check your order and lay out all parts before starting.
4-output harness
Used with the standard Bluetooth/SP105E or handheld controller. Bluetooth Pro uses a different wiring layout.
Flow Series controller
Check which controller you have before wiring or downloading an app. A controller is required; it is included only when selected with the kit.
43-inch dash trim strips
Flexible light strips fit into suitable gaps in dashboard and door trim. Vehicle fit varies.
6-foot JST extensions
Route each strip back to the matching harness or controller output.
Have scissors and a plastic trim tool or squeegee ready. Plan a power connection and wire route appropriate for your vehicle. Keep wiring clear of pedals, moving parts, and airbag deployment areas.
2. Connect & Test Before Installing
Disconnect power before making or changing connections. These are 5V LEDs: never connect a trim strip directly to the vehicle’s 12V supply. Check polarity and align connectors without forcing them.
Standard Bluetooth/SP105E or handheld controller
- Connect the 4-output harness to the regulator using the supplied DT plug.
- Connect the controller to the harness’s single female connection.
- Connect the trim strips to the remaining harness outputs, using extensions as needed.
- Connect the regulator’s positive and negative input leads to the appropriate power source for your vehicle, then power on to test every strip.
Bluetooth Pro 2.0 controller
Connect the regulator to the Bluetooth Pro controller, then connect the strips to the controller’s LED outputs. Match the gray regulator/controller connectors. Follow the labels on your controller for any optional signal inputs.

Confirm that every strip lights and responds correctly before mounting or cutting. Turn power off again before continuing.
3. Fit the Trim Strips & Route Wires
- Choose suitable gaps or splits along the dashboard and door trim. Check the fit before pushing the full strip into place.
- Gently push the strip’s mounting edge into the gap. A plastic squeegee or trim tool can help with a snug fit.
- The strips bend in one direction. Follow the natural bend and avoid forcing tight corners. Some bends or gaps may need additional adhesive.
- Route the strip wires and extensions behind the trim panels toward the harness or controller. Leave enough slack for moving doors and secure the wiring away from pinch points.
Trim gaps vary by vehicle. If a strip will not seat without force, reassess the location rather than damaging the trim.
4. Cut the Dash Trim Strips to Length
With power off, measure the fitted length before cutting. The dash trim strips covered by this guide can be trimmed with household scissors before or after an LED.
Cut only from the free end, away from the attached wire. Do not cut off the wired end. If a strip flickers after a cut passes through an LED, turn power off and trim a little farther back to remove the damaged LED. Reconnect and test before closing the panels.
5. Set Up Your Controller
Bluetooth Pro 2.0: MotoAuto
Use MotoAuto for Bluetooth Pro. Power on the system, enable Bluetooth on your phone, and connect through the app.
Standard Bluetooth/SP105E: Magic LED
Download Magic LED using the QR code supplied with the SP105E controller. Power on the system, enable your phone’s Bluetooth, then open Magic LED and select SP105E inside the app.
If colors or effects are incorrect, use color order GRB and LED type SK6812-RGBW. These settings apply to the SP105E controller.
Handheld remote
Use the supplied handheld remote and the instructions for your selected controller. An app is not required for the handheld-only option.

See the strip fitting and installation process. Use the controller instructions above if your kit has a different controller from the one in the video.
Troubleshooting
No lights
Turn power off. Check the regulator input, polarity, connector alignment, and the wiring layout for your controller. Confirm the LED side receives the specified 5V supply.
Only some strips work
With power off, inspect the affected strip’s extension and output connection. Check any freshly cut end for damage, then retest.
Wrong colors or effects
For SP105E, confirm GRB and SK6812-RGBW in Magic LED. For Bluetooth Pro, follow its MotoAuto settings and controller instructions.
Controller does not appear in the app
Check that the lighting system has power and phone Bluetooth is enabled. Use MotoAuto for Bluetooth Pro or Magic LED for SP105E, and connect inside the correct app.
Common Questions
Can I connect dash trim lights directly to 12V?
No. These Flow Series dash trim LEDs require 5V. Use the correct regulator between the vehicle’s supply and the LED system.
Which app does my Flow Series controller use?
Bluetooth Pro 2.0 uses MotoAuto. Standard Bluetooth/SP105E uses Magic LED. The handheld-only option uses its remote.
Can I cut the dash trim strips?
Yes. With power off, trim the free end away from the attached wire. Measure first and keep the wired end intact.
Will the strips fit every dashboard or door panel?
Fit depends on the vehicle’s trim gaps and bends. Test the fit and the lights before cutting or securing the strips.
Is a controller included with the kit?
A controller is required, but is included only when selected with your order. The “No Controller Needed” option is for customers who already have a compatible controller.
