Hot Shot Plus

The Hot Shot Plus starter relay from Painless Wiring is a 30-amp, 12-volt electrical control module designed for vehicles requiring quick, reliable starter engagement without running full amperage through factory ignition switches. This universal kit addresses a common issue in custom wiring applications: factory switches are often undersized for high-draw starters, particularly in modified engines or vehicles with auxiliary electrical demands.

By routing starter current through a dedicated relay, the Hot Shot Plus protects original switch contacts from premature wear and enables push-button convenience for enthusiasts building custom hot rods, vintage restorations, or specialized off-road platforms. The relay operates on a simple principle: a low-current signal from your push-button switch or ignition triggers the relay coil, which then closes heavy-duty contacts rated for 30 amps of starter motor current. This design helps eliminate voltage drop across long wire runs and reduces electrical stress on factory components.

Builders of classic cars, hot rods, and custom trucks will find this relay particularly beneficial as it allows for reliable starter engagement without compromising the integrity of factory ignition systems. The included wiring pigtail simplifies installation by providing pre-terminated connections that meet industry standards for automotive electrical systems. Its compact size ensures it fits easily in engine bays, under seats, or mounted to interior panels without occupying excessive space.
