(First of all, I'm brand new to the forum so please forgive if this is in the wrong section or not following the rules) Hey there all, I'm looking to install a train horn (yes, childish I know, but the stock beeper doesn't cut it anymore after almost being run off the road multiple times) and I wanted to mount the air compressor and tank in the trunk area somewhere, and mount the horns themselves underneath the car in the vast space under the trunk. But I don't want to have to drill any holes through my trunk floor to wire it if possible. So does anyone know of a way to wire something from the trunk to the underbody? (behind a panel or something??) Also to wire something from the trunk to the battery? Is there a way to wire it under some panels or the floor so you can't see the wires? Any help would be appreciated! Thanks!
