"One person is not getting switched power, but rather constant power. My initial assumption is that the wrong black striped wire was used, my take from the other threads is that one of the black striped wires is constant and the other is switched. Again, any insight fellow members could give me will be helpful"

I actually have that problem... where I am getting constant power to my ESCORT PASSPORT... it doesn't turn off even when the ignition is off! Should the pins be going elsewhere? Please advise (2003 G35)

 

where did you get your power from?

if you take the black/red wire in the ignition harness that is switched 12v and is hot when the engine is cranking
if you take the white/black wire in the ignition harness that is switched 12v and is low when cranking.
if you take the white/blue wire in the ignition harness that is 12v all the time.
if you are taking power from the bcm and you have the white/red wire that is constant 12v

it all really depends where you are taking your power from.
