Stock Components Removal
It is best to Google “how to remove bumper” for your particular trim
Driver Side Hole Location
The top shroud is integrated into the bumper and will come off as a single piece with the bumper. It is necessary to drill two ¼” holes into this shroud to install the Big Mouth but it is recommended to start with a pilot hole before using the ¼” drill bit.
Use the following references to locate the hole center. Start with the driver- side hole:
- (a) straight edge on the shroud
- (b) the edges that divide the inlet
- (c) the tape measure
- (d) bolt holes on the Big Mouth. This reference is particularly helpful for the driver-side hole.
Mark and drill the driver-side hole. Confirm this hole location is correct before locating the passenger side hole. An enlarged version of this image is available on the next slide and additional images are provided for locating the passenger side hole (slide 7).
Passenger Side Hole Location
Use the same references from slide 4 along with these images to locate the hole center for the passenger side hole. Mark and drill the passenger side hole.
Big Mouth Installation
Once the holes are drilled, install the Big Mouth using the provided M5 x 22mm button head screws and the M5 lock nuts. DO NOT OVERTORQUE.

Wiring Harness
Wiring Harness Schematic
There is an extra black wire in your kit, you can use it to ground the switch gold terminal if preferred, however not mandatory.
Controller Location
Clean the surface shown with a dry cloth and use the provided double-sided tape to adhere the Diode Dynamics controller to the shown location. Ensure the cables are facing passenger side. Connect the LED strip to one of the controller ports (line up the arrows on the connectors!). The other 3 ports can accept any Diode Dynamics lighting strip for underglow or underhood lighting (sold separately). Connect
Big Mouth Wiring
Connect the grey pigtail connector to the controller and fasten the ground
lugs to a point on the metal chassis. Follow the wiring harness schematic
(slide 11) to properly hook up the button switch.
Use the car battery to supply power to the Lit Kit. Undo the nut located on the positive terminal of the battery and fasten the power cable to it as shown. Take care to route the wire through the indicated channel to avoid damaging it when the terminal cover is reinstalled.
Make use of the provided zip ties and cable clips to bundle and organize the excess wire to avoid straining or damaging the wire.
Phone App
Download the Diode Dynamics app and connect via Bluetooth.
How to connect to the app:
- After installing the app from the app store, open the app on your device.
- Cycle the power to the Bluetooth controller by unplugging it and plugging it back in or flick the power switch and wait a few seconds, then turn it back on.
- Wait for the app to detect the controller, it will pop up on the app screen as a Bluetooth controller. If necessary, cycle the power once more to refresh the controller.
- Once the controller shows up on the app, click it and connect. You have 30 seconds to select the controller once it shows up on the app. After 30 second you will need to refresh again to detect the controller again.
- Note that if you mounted your controller behind a lot of metal components, this may degrade the signal and range.
Final Assembly Review
Review the install and make sure nothing is binding or causing any preload on any parts, loosen and retighten if adjustment is necessary.
Re-assemble the bumper the same way it was removed to complete installation.
