Wire Harness 77-86 XS650 European
Without flasher cancel unit and light checker connection
Harnesses are made from new Yamaha genuine original patterns, so it's critical that you
order the correct model/year part number to match your bike (See our Model ID Chart).
To further verify, check your old harness by looking for the OEM part number on the white tape strip
located on the old harness (usually near the ignition coil connection area on the main loom).
