I've disconnected that little SOB on my '05 and on my '08, on a buddies '08 and, just today, on an '07. I forget where it was on the '05, but I know I didn't need to come in through the front. For the Gen II bikes, remove the two Right side panels (B and D?): three hex bolts and two quick release fasteners, plus the damn headlight adjustment cable. (Use a 17 mm socket for that one, after you've removed the tiny set screw in the knob.) Near the center of the bike you will find a big connector. That's not the one. Go futher inboard and slightly "behind" it -- that is, further towards the innards of the bike from where you are standing, but actually closer to the bike's front end -- and you will find a slightly smaller connector. Squeeze the far side of it and -- with a couple of cuss words -- it'll come apart. Like others have said, I've never seen a loop...just two separate parts of this connector. Turn on the key and move the windshield, turn off the key and see if it stays put. It did? Then you got the right connector! If not, put that one back together and keep trying.
BTW, I've never disconnected the battery for this and haven;t had a problem...so far. It is a GREAT mod!
