Hi, okay, this sounds better. In generell you need four wires to connect the generator. At first you have to disconnect the old controller. At the old controller connect the blue cable comming from the dashboard with the black-red cable going to the generator. Take the brown cabel from the old controller and connect it to the ground. The black one is not longer needed.
Now go to the generator itself. The brown one is ground and goes to the generator housing. The black-red one is the controll light at the dashboard and is to be connected with the D+ port at the generator. The big red one is B+ and Port W, if needed, is for the speedometer. The black one is not to be connected with the generator any longer .
