I want to connect a torque sensor to this controller

Do you know this ebike controller? Someone used it with a throttle only and cut all the other wires. I want to connect a BB torque sensor. Do you know how?

A picture of the label (if it has one) would be helpful.

It's probably easiest to start over with a new controller. Look for one that has compatible connectors.

Very few controllers, besides on factory ebikes, support torque sensing PAS. Affordable options include using open source firmware with KT controller, or adding a Cycle Analyst 3 that can accept the torque sensing PAS and convert it into a throttle signal.
