Good to see you got the sidecar Bob! Drilling that hole was a real scary part of the install, mostly due to it being in the most expensive part of the bike if you screw up! Really hard to un-drill it! When you do get your bike out of that snow bank and get started give me a call and I'll give you my pit falls to getting mine hooked up, there are a number of things I would do differently based on my experiences.
I've still got to get the lights wired up and do a proper test ride, just have to wait for the ice and snow to go away....
