I bought a car Suzuki Alto. The model is HA37S. Install the Changer F2S front and rear dashcam bought on Amazon. I’m checking up and down with a powerbank. Temporarily put the rear camera with duct tape. Peel off this pillar to power the forward camera. It’s a little bent, but I don’t care about it. I’m thinking of getting power from the car audio. Use a wiring guide like this. Put the wire in the gap at the top of the windshield. I haven’t installed the car audio yet. I will take power from the cigar socket. Next, wire the video signal to the rear camera. It will be embedded at the top of the window like this. Also use a wire guide to route a pillar. Go through the ceiling from here. Connect to the rear camera. Bundle up the excess wires and hide them in the ceiling. Attach the rear camera with double-sided tape Attach with the cable clip, the wiring is complete. This is an actual running video. This McDonald’s drive-thru parking is very dangerous. There is a traffic controller, but he is of no use. This dashcam has GPS, but GPS has never worked. I think it’s a problem.
