I did not finish the rear dash cam yet. I am waiting for experienced veterans to solve my problems

but I think for the Honda Jazz Mk4 we need to lead the cable through the rubber cable retainer tube at point
A so it can enter the car's hatch door. Then there is a problem because in the MK4 there is no visible opening to lead the cable to the rear window.
As far as I know now we need to use the "
tailgate trim". The tailgate trim is the plastic piece at point B. So the rear camera cable needs to go through the rubber cable retainer tube at A to the hatch door. Then it is inside the hatch door where we need it. Then we need to lead the cable to point B. This is the "tailgate trim". The plastic trim needs to be taken off to be able to use a "cable guide" to bring the cable from point A to point B. Inside that plastic trim we can then drill a small hole and use a rubber seal and pull the cable through to the window and mount the camera plus attach the cable.
I have not done this yet because I am waiting for people who have done this before I have or have alternative solution. Else I will discuss it first with my Honda dealer.
