If you already own the Velossa Tech Civic SI BIG MOUTH, skip to slide 10 to see install and wiring instructions.

Driver Side Hole Location

Remove the stock shroud to allow for installation of the Big Mouth. Hold on to the pop-up retainer clips that retain the shroud. An OEM retainer clip will be used later to install the Big Mouth.

Remove Stock Components

Remove the indicated air intake assembly by undoing the indicated bolts and plastic push clip.

Loosen (no need to remove) the indicated bolts just enough to allow the section of frame to flex (left). Position the Big Mouth such that the round protrusion lines up with the hole in the section of frame (right).

Big Mouth Installation

Use the supplied M6 x 40mm cap screw and OEM retainer push clip to fasten the Big Mouth at the shown locations. DO NOT OVERTORQUE.

Use the supplied #8 screw and fender washer to fasten the Big Mouth from the top. DO NOT OVERTORQUE.

Once the Big Mouth has been fastened through all 3 points, re-attach the section of frame and stock air intake components that were removed/loosened prior to install. The Big Mouth should feel sturdy and free of any interference.

Wiring Harness

Wiring Harness Schematic

Big Mouth Wiring

Route the LED strip cable through the indicated opening.

Undo the indicated bolt to fasten both black ground wires to the ground location shown below.

Controller Location

Clean the surface with a dry cloth and use the provided double-sided tape to adhere the Diode Dynamics controller to the shown location. 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).

Big Mouth Wiring

Connect the grey pigtail connector to the controller. Route the red wire from the pigtail connector around the fuse box and towards the battery as shown. Bundle most of the red wire together using one of the supplied zip ties while reserving ~6″ of wire for the next connection.

Follow the wiring harness schematic (slide 12) to properly hook up the switch. Bundle the excess wire as shown and reserve ~12″ of red wire for the next connection.

Secure the switch to the wire loom using one of the supplied zip ties and conceal the bundles of wire in the crevice shown below. Be careful not to subject any wires or connectors to strain.

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 avoid damaging the wire when reinstalling the terminal cover. Use any leftover zip ties and cable clips to organize and conceal any excess wire.

Phone App

Download the Diode Dynamics app and connect via Bluetooth.

How to connect to the app:

1. After installing the app from the app store, open the app on your device.
2. 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.
3. 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.
4. 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.
5. Note that if you mounted your controller behind a lot of metal components, this may degrade the signal and range.

Final Assembly Review
