There are new versions of the Chapter 40 (Lighting) than the one that came with my lighting kit and it was a little confusing because the instructions for installing the eyeball cockpit light have you wiring up a potentiometer and a housing for it. I didn't get that. Browing around Van's website, it seems clear that it's either included in newer kits OR available as an option for $110. Since I'll be flying under light sport/sport pilot rules, I can't fly at night so I don't need to spend $110 to dim a light I'm not going to use in the first place. I also traced various wiring up around the cockpit rollbar that doesn't exactly match my instructions. There is a two wire lead coming out of the connector at the canopy latch unit and I THINK that's designed to be wired to the eyeball light; it appears to be a common ground, which makes sense. I found a bag with two ES-00141s -- butt splices for 22-26 gauge wire. But my standard crimpers won't crimp a butt splice that small -- it's a tiny wire. So I'll have to come up with something (a pair of pliers?). So, anyway, all I got done besides shoveling more snow at the hangar was riveting on the eyeball light bracket.
