I tagged this onto a previous post, but got no response. I thought it might do better standalone.
I have installed a license plate backup camera which is supported by the Alpine head unit I used to replace my CDR-220 but I can't see a way to get the cables through the firewall. All the cable bundles seem to disappear into the top of the fender well and I can't see the boot where they pass through the firewall. Does anyone know an easy route to get a cable from the rear trunk into the console where I have snaked the wiring from the head unit?
Thanks,
Al
