I am looking for a diagram that shows how to hookup two intermatic timers to the pool pump and the booster pump. Running 220volts

You will not find a diagram for what you are specifically doing.
The timers should have come with some generic diagrams, but the folks who typically install these systems don't need diagrams. Systems like this are field built/designed.

Basically from 240 Volt breakers to 240 volt timers Line In, Load is your 2 pumps, Set your On/Off Times. Intermatic make a nice Timer that has Battery Backup to keep timer in sync.
Correct Grounding, Conductors, and Protection must be observed as Electricity is Dangerous if not done correctly.
This is Intermatic's page on their timers, Select yours and others, you can download or view the Manual.
