Reply to "Wiring ERR Chuff/Puff board new style to Cruise Commander 4.1"

That's not my board, that's the old ERR board that hasn't been made in years.

If you want real chuffing smoke, smoke at idle, and even Rule-17 LED headlight and automatic cab light control, consider my product. Super-Chuffer II.

Here's the instructions for the ERR board you have: ERR Smoke Fan Chuffer Install Notes.pdf

Here's the schematic of that board, as you can see, it's just a power supply and a couple of transistors to isolate the chuff switch from the fan.
