You might consider reworking the wires a little while you have it on the bench. There's a little too much copper showing outside those connectors, especially that green one on #1. If the green one touches the white one, hopefully, only a circuit breaker will trip.
Not sure what the wires from #7&8 are routed to in the second photo, is the black one clipped?
A basic question: Have you simply taken the hot/black and neutral/white wires inside the freezer, cut them, and inserted the stc1000. And except for the green wire, the wires are all pre-existing? If so that lower photo will not work if #7 has the green wire and #8 has the white wire. The first time the controller turns on, 120vac will be applied to the neutral buss of the freezer and hopefully that won't let any smoke out.
