Handlebar conversion brake light issues

[Chewfried]

Hi all I'm new here. Just purchased a 2019 Vitpilen 401. The previous owner had installed riser bars to the bike and I wanted to convert back to the clip ons that originally come with the bike. I decided to skip watching a YouTube video for instructions and started taking it apart. I ended up ripping the electrical connection from the front brake light. After I reinstalled the original bars I started working on the turn signal connection. I got it all put back together and the connections to the right pins. When I went to test the bike I noticed the brake lights weren't working for Both the front and rear brakes. I have checked the corresponding fuse and all the others and have found none are blown. I don't know where to start with test connections throughout the wiring or what other next steps could be. Any Help would be awesome. Thanks!

Does the tail light (low-intensity red light) illuminate? If so, then the Blue wire (Brake) that goes to the tail light is broken somewhere between the tail light and the handlebars. Double-check your splicing of that wire.

If the tail light does not illuminate then check if the right-hand handlebar switch is backlit. If it’s not then the F6 fuse is likely blown.

Thank you! The tail light low-intensity does work and stays constant. I never touched the back brake and that one doesn't work either. Do you know where I would find the blue wire?

Is it these blue wires? when I took of the seat these connecters weren't plugged in anywhere.

No, those connectors are for a 12V accessory. If you look close that’s a blue-with-a-red-stripe wire, not solid blue.

The solid blue wire is the Brake light, and goes from the Front & Rear brake switches at the front of the bike to the tail light. The rear brake switch is on ABS module behind and above the radiator, and its wires (blue and brown) go into the large junction box behind the headlight. Another set of blue & brown wires go from the Front brake switch on the handlebars into this junction box. Somewhere this blue wire got disturbed near the switches up front.

Also, this info is from the 2022 wiring diagram, I’m not sure if wire colors were changed from your 2019 model.
