Wiring Help

[Nomnomnom]

Hello! This may be a long shot, but I was wondering if anyone could help me.

I want to wire a circupool edge 40 to the same intermatic pool timer that my pump is wired to. How do you go about wiring them to the same timer?

I attached a picture of the pool timer. Sorry I couldn't find a model number or brand

It's an Intermatic timer. Probably a T104.
Is it laying on the ground? What is that debris inside the timer enclosure? Mounting off the ground and cleaning out the enclosure should be the first priority from a safety standpoint. If the rusting is extensive, the entire enclosure and timer mechanism should be replaced. Also inspect the conduit and wiring for issues. Looks like a good portion of the wire insulation is fried.
