hey new Harley owner here i recently purchased an 03 FLHTP police bike and i have a few questions. first is there a passenger seat that i can use in conjunction with the air ride seat that comes on a police edition bike or will i have to change the whole setup. second my bike has the front fairing on it with no radio, does anyone know if there is a wiring harness already there or will i have to run all my own wires? any help would be great
