How do you change the camshaft sensor on a 1996 Chevy Tahoe?

its in the distributor 2 screws hold the cap on then pull the rotor again 2 screws the electrical connection going into the distributor is the cam position sensor, its held in with 2 more screws. turn the engine over until it lines up so u can get it out and ur done! about a 20 minute job.
