Thanks. Yeah, I'm still debating with myself on whether or not I want to add the bags or keep it naked. I like it the way it is, but I would like to be able to take some longer trips on it. My plan would be to just go through the trouble of installing the bags when I wanted to journey - then I realized I'd probably need fairings to deal with the wind. The two hook was kind of a bonus.
Is your advice about checking the wires general or related to installing fairings and bags?
Edit to add: One thing I am not yet clear on is whether I'll need to replace the seat to get the trunk on. I thought I read somewhere that the seats on the naked were a bit bigger or farther back, making it harder to mount the trunk. But I also can't remember if I read that about the difference between the '81 the '83 - don't know if you'd know.
