Connect to car fuse box

1. You will need a circuit tester or multimeter to test if a fuse is ignition switched or always on.

2. Make sure the key is removed from the ignition before installing hardwire kit.
   Using a fuse puller or a pair of pliers, gently remove the fuse you identified.

3. Install the fuse for the hardwire kit -to the fuse you identified and removed, inserting the power wire into the fuse with the correct orientation.

For ACC Box (Connect with Red Wire):

1. Turn off the car completely, and find the fuse that does not turn on when the car is off.
2. Restart the ignition with the key and test whether the interface is powered on when the car is started.

For BAT Box (Connect with Yellow Wire):
Please turn off the car and remove the key to see which fuse slots stays lit on.
PS: Requirements for BAT interface:

Please select the constant current interface
below 15A and no other equipment is using electricity.

For Ground the hardwire kit (Connect with Black Wire):
Find the negative connector (ground) and slide or screw the black wire under the metal bolt, not to the plastic part. (You will need to use a tool to fully loosen the nut or bolt of your choice of ground negative, then slide the black wire in and retighten. A loose ground can cause power problems with dash cam. )

Test your installation

1. Connect the three-core power cord of hardwire kit in the fuse box of the car.
2. The double-ended power cord: one end is connected to the output end (DC OUT) of radar, and the other end is connected to the recorder.
3. If everything was installed correctly, you can see dash cam turn on and begin recording!
4. At this point, you can go ahead and reinstall all interior panels that were removed.
5. After confirming no problem, hide the power cord along the car gap until to the middle of the windshield and the roof.

About connect Radar & Dash Cam

1. Please confirm the switch button face of radar must be facing the car.（it is the front side）
2. Select the location of the radar on the windshield. (try to avoid the black dot film on the original glass)
3. Double-ended cable: TYPE-C port to the DC OUT of radar. The other TYPE-C is connect to the power port on Dash cam.

Note: (Please follow these instructions strictly!)

1. Different power interface in different dash cam, please connect the wire according to the interface of dash cam.
2. Incorrect connection of the interface may lead to abnormal conditions of dash cam!

About Installation of Radar

1. The radar installation should avoid the black heat insulation spot on the top of the front window in the car.

2. Radar must not be obscured by rearview mirrors or anything else.
   (Because this is a double-sided radar induction, if the radar sensing surface is blocked, the sensing signal will not be able to be emitted and thus will not work effectively.）

3. The switch button face of radar must be facing the car.

4. Select the location where you want to place the radar, peel off the protective film from the 3M adhesive holder and stick it on the windshield of the car.

PS: Since the double-ended cable is 0.4m long,
please control the position between radar and
dash cam before pasting radar and dashcam.
(Avoid the double-ended cable is not long enough because the distance between radar and dashcam is too far.)
