Gary,
I used the wire plug from the trunk and spliced it into the harness that came with the tailight. hard wired the new tailight into the exsisting wiring, (sorry no pics of that). I also went to Radio Shack and got a 4 pin plug for the rear speakers and spliced that into the speaker wires under the seat so I don't have to fool with going under the side cover and plugging and unplugging those OEM bullet plugs (first plug in picture).

I also did a different mod on the rails. I did and angled cut on Both holes, so I did not have to modify the front of the rails.

This way you can drop it right on, and when the nuts are on, you can barely tell its been cut. And the trunk will stay on even without the nuts tightened, the weight of the trunk alone will hold it on. nothing against the recommended mod, but this required less modification/cuts to the brackets. It wont come off even if you hit a good bump. I know because i forgot to tighten the bolts and didnt notice until 500 miles later, and only noticed when i slammed the lid. If you do this... make sure all the cuts are at the same angle!
I also ran with an small powered antenna that fits under the seat, but I hook up the regular antenna for touring, better reception and range.
In all , I can change from Super to regular in under 10 min... the only reason it takes that long is because I have a chrome rail that goes behind the seat when I run a standard seat.

Hope it helps.
Brad
