Can anyone tell me what this is? It is riveted to the blower motor box on our 1976 High Boy body. We are taking a '76 body and put it on a '73 frame. I can't find the those colored wires in any diagrams from '73-'79. I'm hoping someone here known what it is. We are also completely rewiring the truck, so I need to know what wires to connect where. The truck does have AC and the wires were cut by the person that removed the body from the old frame. At first we thought it was the blower resistor, but we found that on the inside of the truck.
So that is on top of the (a/c evaporative assembly) evaporator box in the engine compartment. I have never seen anything ever attached there that has elec wiring going to it. Hopefully someone has seen one and can tell us what it is.

Possible an aftermarket clutch cycling switch to keep the evaporator from icing up??
Well since we are guessing,
My guess is: Due to the size of the power bat and grd wires used possibly an electric heating element used to warm cab until the engine warms up used in real cold states...
MY GUESS..

I like that idea. My 2011 F350 PSD has the "rapid supplemental heat" option and it is exactly as you described, an electrical heating element next to heater core. I can start the truck cold in morning (below freezing), without block heater plugged in, and within a few blocks of driving I'll already have warm air coming from heater. I do know that option requires a bigger alternator when you add it and it sucks quite a bit of power from my understanding.
I'm not sure when they started offering that option from factory, but they had to get the idea for it from somewhere.
I was thinking some sort of either Ford or aftermarket add on that, would drop a heat element down in front of the blower fan, hole saw would make nice hole.
