Well I thought I could see which wire I tapped for the APPS, but can't see it without removing the whole Bell Crank assembly. I taped and wired loomed it well. Don't have time tonight to do that. Still pretty sure it is the br/yl wire. I did not have any trouble programming the contoller for WOT with the tap. I did mount the controller on the inside kick panel so I could see the lights.
