Ok I pulled my stock HK unit out of my 2010 RG and sold it to a guy and shipped it. Anyway he calls me last night and says that the unit does not work. He tells me that he is installing it into a 05 electra glide. He took it to a harley dealer and they told him they could not get it to work. Now the unit worked fine when I pulled it out, in fact if it did not work I could of gotten it covered under warranty. So here is the question will the 10 hk work in a 05????
