This is a hard one because we don't have one single "signal" wire. There are two coils in our ignition. Black/blue stripe goes to coil 1 and the brown goes to coil 2. The center wire black/red stripe PIN 6 powers the coil from the ASD relay. If you look at the coil pack connector you will see these 3 wires. So in my mind it comes down to either the black/red stripe wire or the black/white stripe wire.

Yeah, in my conversations with him, I thought ignition wire that I use with MS (the black/white). But he only wants to shut down spark so the black/white won't work. The next obvious to me would be the black/red because that feeds power to the coils. But I'm not sure if there is any single wire that would feed this from the ECU. Therefore it would have to be picked up by the coil plug.
