Hello, I am new to this forum and have a 2015 Optima EX. I purchased the NikoMaku AS4 max and planning to hardwire the power adapter. I have looked all over on the net and youtube and nothing for this model Kia. So I am planning to run the wire for the camera along the left headliner down to the back seat. But this is where I get into the weeds. What is the best way from there to run it into the trunk. I currently have an Auto Vox wireless cam but not happy with the performance of it. Thanks in advance for any advice you can give me.
