1974 Brain Box saves the day.
Just did a little test run up on my '76 D100 Truck, checking the heat at the factory heat sinks. Tried multiple different modules all the same.
They run like 10° above outside temperature here idling a few minutes. Temp may go a little higher running them down the road.
I was surprised at the temp at the top terminals of the 4 post ballast resistor, got pretty warm like 180°, tried another ballast resistor and was the same.
Bottom terminals were cool. Guess they are supposed to run like that, just have never taken a heat test gun to them before.
