You do need to keep the connector plugged in (with those two wires cut) to sucessfully do the mod. If you just unplug the connector, the TPWS light will immediately come on and will stay on until it is plugged back in.

Cutting those two wires fools the Tire Pressure Warning System into thinking that the car is not moving and the engine is not running. The TPWS will not report an error if it doesn't hear from the tire sensors as long as the car is not rolling and the engine is not running.

We have the light on and are happy to just disable the system by cutting the wires. Someone said it only works if no light is on which is not the case here.
Can someone suggest a way to get the idiot light off AND disable the TPWS system please?
