QUOTE from the seller at this afternoon's speedster auction on BaT: "the seats are both dual zone heated, the heater adjuster knob on the center tunnel is there just for looks, it can be hooked up however."
Can be hooked up, but it struck me that on a car with no heater boxes, no ducting, no floor vents, and no defroster vents, it might be cheaper to hook the knob up to cruise control or ground clearance than to heat.
