Default yamaha tach install??

Iam just installing the tach gauge only to the yamaha key switch. My question do I need to install the harness that has the two fuses or can I install it without? Thanks max

Good wiring practices would have a fuse in the circuit from the key switch to the gauges.

The fuse protecting the wiring to the dash is rated at 20 amps I recall. The wire gauge from the key switch to the gauges is probably insufficient for 20 amps. Thus the Yamaha mini-harness uses a lesser rated inline fuse.

Plus, with the Yamaha harness it will be plug and play. Assuming you are installing a Yamaha tachometer.
