Vintage Air system, blower will not shut off

[vstol]

I have just installed a Vintage heating and air system in my 71 Corvette and the darn blower will not shut off. I am working with their tech department and we have replaced the ECM and wire harness but the blower still runs. I have sync'd it 10 plus times according to their manual and nothing. I will contact them again on Monday but thought I would flip this over to you guys? Thanks

What did you connect the purple wire to?

The AC/Htr fuse on the American auto wire panel.

Does that turn off with the ignition off? I don't think it does but will double check tomorrow.

The purple wire needs to be unpowered when the ignition is off. A pink wire....

Thanks Don it does not turn off so I will try that today.

No effect and the blower stays on with the ign on only it will shut off with the power off.
