I'm trying to figure out how to hook up some carb heaters for use with my motorycle (2xCVK30s). This is the electric heater retrofit kit for several Prairie ATVs which I'm trying to adapt so I can ride without icing in the winter.

I'd *love* to get my hands on the schematics for these guys. Otherwise, I'd like to know what's on the following wires:

Auxilliary Power Connector -- is black/yellow ground? If not, is it switched through the ignition?
Rear brake light switch -- is brown hot? Is it switched through the ignition? Does it come on it park, or just on? (Do ATVs have a park position?)
Ignition Coil (most important one!) - Is green/white hot or ground? Do you know if it's "always on", or does it pulse?

Any info would be very much appreciated! These look like good little kits (99995-1422, 99995-1378.. I think only the instruction sheet is different), you use some of the extra holes in the bottom of the carbs for a heater and a sensor which get glued in with high-temp silicone.

Hell, if anybody knows why it taps the ignition coil wires, I'd be interested. I'm suspecting it's so that it doesn't come on until the motor runs, sort of like the headlight on a motorcycle. My bike has a relay which feeds itself for the headlight which is triggered by either the ignition coil or the pickup coil (can't remember which). That way, you still have lots of juice for the starter to crank over the motor.
