Do I need to purchase the wiring kit listed under the add-ons for my GlowShift gauge package, or is wiring included with the gauges?Updated an hour ago

GlowShift gauges include the wiring harnesses needed to connect the gauges. The optional wiring kit listed under the add-ons makes it easier to connect the wiring for multiple gauges and is recommended if you do not already have 18–22 gauge automotive-grade wire available to extend the wires as needed for your installation.
