If you didn't get the NUOH.... Non Ultra Overlay Harness.... you need it. $129 list. Just did this to my 2011 SESG2 and was looking at the wiring diagrams for your bike.... You need the overlay harness
I believe that the '09 SERG and the SESG1's and 2's use the same radio without all the XM, NAV and COM etc. All I bought was the iPod Interface Module from Jenni at 20% off and then when I found out I needed the 35-pin connector cheap kit, I ordered that from my local dealer as the shipping from Jenni would be more than the 20% discount and tax.
I used "just" the cheap 35-pin connector with the mini 2 wire harness and even with the reversed two wires in the 35-pin plug, the iPod worked the way it was supposed to. When I switched the two wires, the sound was now centered and both speakers worked just as though I had my iPod in the AUX jack.
There may be some difference between fixed and batwing fairing bikes, but if the radio options are the same, lack of anything but the radio, it "should" work with the mini 35-pin kit and without the $129 cable set.
I could be wrong, but it worked for me without an extra $100.00.
