Sorry, I leave work at 3:30. I only needed a jacket liner that was electric and not the pants (the pants I wore thin ski pants over my work pants since they have the big zipper at the bottom). Don't forget to flip the foot scoops in the winter too. Grips of course are high or low and are connected to the ignition so it won't kill the battery. As for the jacket, it is a Gerbing's. You buy a liner so it fits snug to you - minimal air gap. I simply remove the insulated layer from my riding jacket and everything fits great. I also wear a neck muffler pulled up to my chin (our Kohl's carries nice ones at the moment). I found that this configuration worked great for me.
I assembled a digital controller instead of buying one - it's just a digital motor speed controller that pulses the current so none is wasted. I used a 4-wire trailer connector, switch, and relay to hook everything up and put it in a small black box from Radio Shack Velcroed to a dash shelf I made. Fun little project - no soldering, just crimping. I could add 2 more in there but have never needed to. It all gets removed in the spring by the two screws holding the plate.
