Improve Your Electrical System’s Performance with Painless Performance Relay Kits

An easy way to improve the reliability of your vehicle’s electrical system is using relays to control devices like electric fuel pumps, fans, and lights. Relays minimize voltage drop, can handle much higher current load than a simple switch, and let you use the proper size fuse or circuit breaker for each component. Painless Performance makes relay kits that make it easy to upgrade your electrical system. Let’s take a look at a few.

Electric Fuel Pump Relay Kit
This kit is designed to prevent voltage drops at the fuel pump to maintain constant fuel pressure and prevent amperage overloads from damaging the vehicle's electrical system. It’s a good idea for street use and a must for racing. The kit includes a 30 amp heavy-duty relay; 30 amp circuit breaker, relay base with wiring harness; crimp terminals; and mounting hardware. You can get a kit with or without weatherproof components.

Electric Fan Relay Kits
Summit Racing carries several types of electric fan relay kits. All provide constant voltage to the fan, protect it from voltage and amperage spikes, and prevent the fan from backfeeding voltage through the vehicle's wire harness. Choices include:
• Single fan kit with 40 amp relay and 30 amp circuit breaker
• Heavy-duty kit with 70 amp relay and circuit breaker for high amperage single or standard dual electric fans
• Kits with thermostatic fan activation/fan off switch or adjustable-temperature thermostatic switch to set fan activation and shutoff points
• Dual-activation kits with thermostatic switch that activates the fan when A/C is turned on
• Kits that allow a powertrain control module/ECU to activate the fan—ideal for use with aftermarket EFI systems

Halogen Headlight Conversion Relay Kit
Converting to halogen headlights? This harness draws power directly from the battery, through the relays, and to the headlights, providing full power to the bulbs. It includes two 40 amp weatherproof relays with bases, a weatherproof 30 amp fuse, and connectors to mate the harness to your factory headlights and electrical system. The kit is designed for #9004 and #9007 halogen bulbs.

Trail Rocker Relay Control System
The Trail Rocker gives you control of up to eight 12 volt electrical accessories—from light bars to air lockers—on your truck or off-roader. The heart of this kit is the power center with eight 30 amp fuses and relays enclosed in a weatherproof housing.  The power center is prewired; just route the wiring to your accessories and make the connections. You also get an input harness for a control switch. The Trail Rocker has dedicated wiring to control an electric winch—just get the Painless Winch Control Switch and you’re in business.

Summit Racing also carries Painless Performance relay kits for electric water pumps, starters, auxiliary and brake lights, and other functions.
