yet another DC Controls question

[GregD]

I am also installing the DC controller and its almost done. (had to wait for new surge protector) My understanding is that if you hook the yellow wire to the ignition it guarantees the fan will shut off with the ignition off. I want mine to shut off with the ignition so I will be hooking my yellow wire up for sure. Hope that helps.

Adam, I'm in agreement with you that you need the yellow hooked to switched 12 volt if you want it to shutoff when you turn off the ignition. But do I need it wired to a constant 12 volt if I want the fan to continue to run after the ignition is off until it reaches the setpoint temp? Seems to do be doing what I want without the yellow wire but I want to make sure I am not damaging anything or causing other issues without it.
thx
