David,
Its a different solenoid. Its the solenoid with two nipples facing up and a filter like thing in the back (rectangular box on the back of the solenoid). It actually looks VERY similar to purge control solenoid except the purge control solenoid doesn't have the little box thing in the back of the solenoid. If you use any other solenoid you WILL have issue with your sequential system.
The diagram is correct and you have to use the correct solenoid! The "E" solenoid is the same ones as the "F", "H", "I", and "J".
