cab below the windshield, and provides a duct that supplies heated air to the cargo compartment. Kit two takes in cab air
through a duct behind the drivers seat and has two defroster ducts. a separate cab heat distributor and regulator valve, and a
separate duct to heat the drivers footwell. Kit three is identical to kit two except that there three is no regulator valve, and two
fans with individual ON-OFF switches circulate cab air to the defroster ducts. See Vehicle Compartment Heater Kit
