I would think some smaller connectors would be in order with a smaller headlight. Not 100% sure because i haven't put a smaller headlight on but it is pretty tight in there.
As a side note, after I cut the hole in the headlight there are some sharp edges that, to my knowledge, wires are not very fond of. I simply filed the edges as best I could. Then I went to the local auto parts express and bought some of that sticky chrome edge door molding. You'll see some people have used this stuff on the lower edges of their tank. Cut it to length and then very very patiently bent it to fit around the edges of the new cut.
Here is a link to some of the photos all put together. Completely forgot I had done this for a previous thread. Pictures are a little cluttered but I think you'll get the idea. If you need anything more let me know and maybe I can meander out to the garage and add some more photos if that'll help.
