It was subtle but noticeable to me and even more noticeable with the AC on. So after driving the car today, with the harness in still bypass, with the AC on in 96 degree heat it became more evident to me the relative sluggishness of the throttle was not present before the harness was installed.
So I reconnected the brown wires and confirmed the lock was working and went for a drive. I noticed immediately the throttle response was back to its quickness.
I'm not sure what's happening when the brown wire is open but it seems to be having a negative impact on the drivability of my 370Z AT/2011.

I do appreciate all the work put into this solution.
