Okay, so, it is only the high beam on that side that is out, the low beam still works. That means it's not the fuse or relay. Instead, it is either the orange wire that provides power or the light blue wire that provides the ground. That wire couples to the ground for both high beam lights. Testing should be easy. Get a test light and use it to probe the lights socket. With it connected to ground the light should come on when touched to the A pin with the orange wire. With it connected to battery positive power and high beam selected it should light when touching the pink or light blue wire (pin B). Once you figure out which wire is bad you can then check if the problem is in the connector or farther back in the harness. For that take a needle and stick it into the wire then test there. Once you find the problem area it can be repaired. Use a drop of liquid electrical tape to seal the pin holes.
