I went online to a used parts store and I found the Door Jamb Rubber Grommet. It seems there isn’t much space to run Speaker and Camera Wires through the Grommet Connector.
I still need to understand how to disconnect the Grommet connector shown in the picture. There is this slider, which I pull up just a bit in the previous picture of days ago. I think I should pull the slider up further.
I fear that if I’m wrong I will be causing water leaks when it rains.
If you have done similar work through a similar grommet. Is there a way to run Speaker Wire, and/or DashCam wires through the Grommet?
