  1. have a 3 M38A1. No heater. Is there an installation guide available to look at? I need to see this before I order your heater. Do you draw the hot water from the jeep radiator? Is the heater core inside the cabin? Do I only have to pass the water hoses thru the fire wall? Do you have a video showing the installation?
