I think the previous owner tried to by-pass some things on it but I have no idea what these wires go to or why it was by-passed but I do know with it like this the bike runs just fine.the first picture is right before the cluster plug in and before the headlights or turn signals on sun harness and the second picture is right after the plugs for the sun harness. The 3d picture is what color the second pictures wires are! Any ideas?

 

03 CBR What?

 

03 CBR600RR according to other posts. This is the bike with no horn.

 

Stay on target! We're dealing with horn wiring here. Don't get distracted with anything else until you've traced wires from horn-button to other end so you can install and connect horn.

That other box is aftermarket flasher-relay. Depending upon how it's wired
into factory harness, it may or may not work properly with correct blinking rate. Your winker lights aren't even connected properly, so there's absolutely zero way to test flasher relay. Unless of course, you can trace factory flasher relays from dash and see where they go...
