best way to clean up my wiring??

Ok I bought a p3 street fighter for work in a semi rough state for some reason the digital dash wont show my speed and I don't have high beam but I'm wondering the best way to clean up the wiring or should I take it to a shop to get routed?

Any help would be sweet

Depends on your comfort with bike electrics. Personally not too hot with them so its be a hop job but there may be a few on here more handy than myself who could help?

As u not to good I have my l3 and l1 but don't know much bout p3 I'm thinking shop to cut down everything that's not needed
