Gazelle Orange Innergy rebuild

There are two types of KT controller. One works with hall sensors, the other doesn't. Which one do you have?
The listing doesn't say anywhere that it's for sensorless motors. It looks like it's a normal one for sensored motors to me. Sensorless KT controllers are normally square wave ones.
KT sensorless controllers don't work with all motors when sensorless. If I wanted to run sensorless, I'd use a different brand. The cheaper brands don't have such nice control systems for the rider, but they seem to get on much better as far as keeping the motor in sync. The guy that made the original guide for repairing your bike used a KT square wave controller for sensorless motors, which worked, so you'll probably be OK with KT, but IMHO, it's an unnecesssary expense. Here's what he wrote:
"In spite of the article above, my Gazelle’s motor HUB has no HALL Sensors. So I had to find an ebike controller which is compatible with KT displays and can drive the motor without HALL sensors.
The naming of the product is very critical, it should be like controller for Dual mode or sensorless motors. Controllers named as sine wave motors are not able to control motors without HALL sensors — or motors faulty HALL sensors. E.g. I ordered the Dual Mode variant of the beautifully named LOLTRA E-Bike Controller Sine Wave/Dual Mode KT Controller for 36V/48V Electric Bicycle DC Hub Motor and KT Display."

Thanks for that; I’ve ordered that exact model of controller from Aliexpress. I’ll give that a go when it arrives next month. I have to tidy up the wiring in the meantime, can you recommend a method of joining these small wires without soldering, I was looking at these heat shrink connectors? Any other suggestions please?
