12v ambient light power connection: take off the cover of the rear ceiling light and you will see two screws. When you unscrew it, the light will be taken off. Then, remove the B-pillar consisting of two baffles. Remove the bottom first, buckle it all, and then pull it down. Then, you will see two screws on the upper baffle. Unscrew it and pull hard. Then thread, find a suitable length of iron wire, and extend from the ceiling lamp to the B-pillar. Because there is an airbag above the B-pillar, it is soft and will block the wire. At this time, you can remove the soft strip of the B-pillar back door near the back door, let your hand reach into the ceiling, pull out the wire, fix it on the wire, pull it over, connect one section to the ceiling lamp, and then test whether it can be lit, and the other section will come down along the B-pillar. You go to the clutch, the lights are connected in series. Fix the light in the main driving position first, then follow the handbrake or under the foot pad, connect the left rear light, then connect the right rear light, and then go around to the co-pilot to connect the last one.

Wiring mode of indoor ambient light:

1. Ambient light can be embedded in a proper position in the car, cut into the hook line of the air outlet from the fog light and enter the lighting system;

2. Wiring is to connect the positive and negative levels to the lamp wire (that is, to the+-pole), and then put the connected wire harness into the original car lampshade after insulation treatment (it can also be attached to the car scratch bar seat). Note: Some models, such as fog lights, may need to disassemble the bumper in advance;

3. Although there is a lot of speculation about installing ambient lights in the car, don't blindly follow, because the line load used must be greater than the load.
