I am replacing the tub on my '83 CJ7 and there is some electronics on the heater ductwork that I do understand. Just above the vent by the passenger floorboard there is a three wire plug that goes to a coil inside the ductwork. Could someone tell me what this is or it's function? Thanks, Dan.

resister block for fan speeds.
That is the fan speed resistor block.
While you are in there you could convert the heater to a big GM blower that will defrost 'all' the windows, literally cook your feet and allow you to drive at -25 with no gloves, boots, ski pants or parka on. All for about $25.00!
It puts out more on low than the stock one does on high and that is no exaggeration. It will _even_ de-ice that little triangle in the center of the windshield and the passenger mirror corner in a snow storm! I haven't needed to use full defrost yet to do that either which means the toes stay hot.
Here is a link on the job:

There are two blower motors some parts stores have on the shelf. The cheap regular one and a premium one. You want the cheaper one which is the one with the shorter shaft. The premium one has a shaft about 1/4" too long for the Jeep. Best is to take your old motor with you just to make sure.
You just need to make a slightly larger hole in the firewall to fit the larger motor, everything else is a direct fit. The Jeep squirrel cage fan fits right on. I used to have a link on an easy hole cut, but it doesn't work anymore.

You are welcome. Yup, heat is s good thing. My wife got a heated seat pad for xmas and she didn't even plug it in on our last 4 day run. No need.
