The main audio harness is the same from 1998 through 2009, so for power/ground, front speakers, and hand controls, no wiring changes are needed. This means that if you’re installing on a 2 speaker bike without additional options, it’s a simple plug and play situation.
The auxiliary harness (also known as the overlay harness) is where the radical differences between 1998-2005 and 2006-2009 occur. If you plan to run rear speakers from the H/K radio, or utilize the Harman/Kardon XM or intercom modules (like Ultra Classics), then you'll need to buy and install the 2006-2009 overlay harness on your 2005 bike. It can be done, but it does involve some work. The best thing to do here is to obtain a copy of both factory wiring diagrams old and new, and locate the power/ground/speaker wire connection points that suit your particular needs best.
From a calibration/programming point of view, if you can find a Harman/Kardon radio out of a 2006-newer bike that’s already functioning, just plug it in, you’re done. New Harman/Kardon radios come blank from H-D however, and currently the dealers are the only ones who can calibrate/program them properly. Check with your local Harley-Davidson dealer to see if they are willing to help get your new radio programmed before you install it on your older bike.
