The cam sensor is just down & to the rear of the water pump. Take a mirror & a flashlight down the right side of the engine. You should clearly see the connector just below & aft of the water pump.
Replaced mine (*/C 92) without removing any belts but it was REALLY difficult to get the O-ring to fully seat without damage. If I were doing it again I actually would have saved about 1/2 hour if I'd removed the outer belt first.
Be careful not to lose or damage the bolt. They want $16 for it. Can't understand that; doen't look like a special size, length, or anything.
