Anyone with a service manual or otherwise know what the red/white wire anf the white/green wires are designated for on the newer MPI motors? I assume the red/white is power, and the white/greens are the signal?

The ignition coil has one red/white and two white/green wires. I am looking for the proper wire for my shift interrupter switch. It is a normally closed switch (opens or breaks the circuit when shifted)

Thanks in advance
