Anyone know if an impact sensor from an 05 will work with an 06? I see a lot of places advertising one that fits 04 up but the part numbers are different. The dealer says that its 77930-sec-a82. The 05 is 77930-sec-a814. some have a nukmber as 822 m1. Are they just changing the number each year? The dealer really couldn't tell me much.
