There are red, yellow, black, and pink wire colors.

– The red wire connects to the battery+ (it will always have power, regardless of whether the car is on or off).
– The black wire connects to the grounding-.
– The pink wire connects to the fuse box +.
– The yellow wire is for the LED strip and connects to the Left and right headlight turn signal wires..

You can connect the red wire and black wire to the car’s battery, then proceed to connect the other two wires to test. If the LED bars light up for the left and right, this wire connects to the left and right headlight turn signal wires.

There is an insect net included with the grille. We suggest you install the insect net because the gaps in the grille are larger, and the insect net can help prevent insects from getting through.

If you still have problems, please provide the details and send us a video. Then we can have our engineer assist you.
