Occasionally the wires will cross. Injunction of 2 wires is usually indicated by black dot in the junction of 2 lines.
The megasquirt controller uses the throttle position sensor tps to determine when the engine is at or near full throttle to shut off feedback from the o2 sensor when the engine throttle is opening or closing rapidly and needing an accel decel enrichment and when the engine is flooded and needs to be cleared.
