What is the best way to install a new Throttle Position Sensor on my car?

I have a 1996 Chevy Monte Carlo Z34 with a 3.4 engine. I want to install a new Throttle Position Sensor on it. It looks like it will be a real pain to do. Does anyone know any tricks of the trade that might make it easier to do.I think everything on this car is designed to drive you crazy. No room to work on anything under the hood.
