METHOD 2: Hard-wring to the fuse Box If you choose this power method

Above we have introduced the steps to plug-and-play to the rain sensor and separated install the single-channel and dual-channel recorders respectively. The following introduces the steps and methods for connecting power through a fuse box and installing single-channel and dual-channel recorders.
In fact, these two installation methods are basically the same. The only difference is the power connection method. Here we only introduce the method of connecting the fuse box with the S015 power cord. The remaining installation steps are the same as above.

Note: for the convenience of installation, the fuse box power wire is upgraded and optimized. The wire has  its own ACC converter. During installation, it is only necessary to onnect the constant power and ground wire to the fuse box near the glove box of the front door. When the car starts, the recorder  works normally, and when the car is turned off, the recorder is   turned off after a delay of 2 minutes.  

If you choose the method of wiring to the fuse box, continue the previous installation method from step 4.

The status of the fuse box power cord waiting to be connected to the fuse box slot is as shown in the figure below.

We used a pry tool to pry open the cover on the side of the passenger seat. Then let us use the multimeter to find out the BATT+ slot. Take out the multimeter and turn the dial of the multimeter clockwise to the 20V position.

We use the red pen and black pen of the multimeter to touch the constant power slot and negative positions respectively, and let other people help you start the car. If the multimeter shows that it can reach 13~14V, then the position measured by the red pen is the constant slot position of the fuse box. We connect the S015 yellow wire to the constant power slot position and the black wire to the grounding. Then the wiring of S015 has been completed.

The wiring of the power cord of the fuse box has been completed. For other installation steps, please refer to the above mentioned parts and will not be repeated again. This article is for reference only. It is recommended to seek professional installation or on-site guidance.
