Not sure where to put this but basically I have some led panels that I'd like to mount on the rear window. Two panels for the left and right turn signals and there's one panel that I'd like to have illuminate when the brakes are applied. I know that one of the most obvious ways would be to splice them into the rear bulb wires but my confusion comes from knowing what the easiest and best way to run the wires from the trunk all the way to the cabin would be? What ways are there besides using the grommets in the actual engine bay? Or would there be wires in the cabin i.e. under the drivers side panel that I could splice the lights into instead? If there are, I'd much prefer to do it that way rather than extending thin long wires all the way from the trunk. I tried searching for some relevant information but couldn't find much so TIA!
