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!), making sure to route the cables behind the “legs” of the stock intake duct. The other 3 ports can accept any Diode Dynamics lighting strip for underflow or underhood lighting (sold separately). Connect the grey pigtail connector .

BIG MOUTH Wiring

• Follow the wiring harness schematic (slide 8) to properly hook up the switch. Ground both black wires at the bolt that secures the horn.
• Bundle the excess wire as shown and reserve ~30” of red wire for the next connection to the battery. Use zip ties to secure the toggle switch in an accessible area that you see fit.
• 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.

Final Overview

Use the remaining zip ties and cable clips to keep the wiring tidy and free from strain.
