This is for the brand “safety trim”. It’s a controller that slows down the speed of the trim motor in faster flight. It also has runway protection etc. It’s wiring diagrams have a lot of the wires wired in parallel. So you would have two wires attach to the red and two to the black on the motor. And I’m not sure with a 18-22 butt splice if I can put two 20 gauge wires in One end.
