The orange wires are the dash lights both at the cluster and the small signs next to the cables.
Check the plug at the light switch.....and the switch too. Clean contacts and replug firm.
For HI beam, you should have 3 wires on the floor at the foot activated dimmer switch. Check the plugs/contacts...Center wire is hot (I think)
