I kept the plastic base. No need to "wrap" the leads, just bend one to touch the smaller spring and the other on the opposite side in a way that it touches the outer spring.
The smaller spring touches the battery lead at the positive end of the battery. The larger spring touches the body of the light to act as the ground.
One lead touches larger spring
Other lead touches smaller spring
This one is fugly, but another one turned out nice but leads could not be seen by the camera.

Agreed, I've never soldered one. Just bent the legs on the 5mm led, and pushed the SF springs back in place. Makes it easier to replace the LED when you accidentally grab that assembly and drop it into a 6P with two 123's in it. Ask me how I know... 
As an aside, the emitter did actually work for a minute as I sat there and wondered what was wrong with it...

"Hmmm, wonder why it's smoking like that?" "zzzt". lol
If I recall correct some folks were testing Yuji's to see how much and for how long they could go with various amounts of current, and how bright they got. I turned away from the computer screen as torture makes me squeemish.

Wow I'm really surprised how well this turned out. Even more surprised that just bending the led leads under the spring seats is working and holding up to multiple drops.
Interestingly the p60 reflector seems to be working very well with my yuji sample. Not 100 percent sure which beam profile this led is but looking at the pattern from the p60 it's developed a nice tight hotspot with broad, bright spill. And excellent task light and really lights up a room despite its low output running 2AA...
