I'm trying to convert a 2010 Electra Glide Ultra Limited to a Road Glide so I ordered a new fairing interconnect wiring harness from a 2010 FLTRX. The only problem is it's on back order until March, and I ordered it in December. The 09 harness is a different part number than the 10, and I don't know about the 11. Does anyone know what changed on the harness in these years? I wouldn't think there was any major changes, but they do have different part numbers. I'm hoping I can order a different year harness and make it work.
