I am guessing you want to trip a factory limp mode. You could do a few different things but they are all going to trip a check engine light. The best scenario would be to ground all the coil wires. So Take all three ground sides on the coils and tap into them and commonly ground the wires when you want. This will act just like a rev limiter. You could also short out the tps sensor. You are going to have to reset by stopping and turning the car off and starting again. So I do not recommend these as it could be unsafe.
