I need to relocate the Sirius antenna on my '15, it is blocked by the camper. It looks like the antenna is DC3Z-10E893-A, that has a short cable on it so I will need one of the extension cables. I am intending to mount it on the cowling just ahead of the windshield as I have seen others do. Does anyone know which cable assembly I would need? I assume the one going up from the drivers kick to the roof? Is that BC3Z-19A397-A?
