On the 2004-up minivans, interfacing with the PURPLE / brown wire does not seem to be necesary----everything works fine without it. At any rate, though, whatever connections you have made to the PURPLE / brown wire are probably incorrect-------most likely, you got the "crank" and "run" resistors backwards.
