Rather than drop $100 for the non-Ultra overlay harness (which is a huge harness with many connectors you won't use, e.g. rider and passenger headset, tour pak speakers and controls, etc.), get the harness HD offers for the NIM and Ipod modules for under $20 and make-up the connector and wiring you need--easy to do with a parts book and wiring diagram.

HD did NIM and Ipod module buyers a favor buy not requiring them to buy the NUOH and offered the 69200033 harness for $20 for use on the SG, EG Classic, etc.

Whatever you choose to do, good luck with your project.
