AEM 20 Amp Relay Wiring Kit

AEM 20 Amp Relay Wiring Kit (PN 30-2062) | Fuel Pump Harness

Ensure peak performance and full voltage to your aftermarket fuel pumps with the AEM 20 Amp Relay Wiring Kit. Pre-wired 80" harness, circuit breaker & hardware included.

The AEM 20 Amp Relay Wiring Kit (Part # 30-2062) provides a clean, safe, and professional electrical connection for high-draw aftermarket accessories. Standard factory wiring harnesses are rarely built to handle the amperage demands of performance components, often leading to voltage drops, decreased output, or blown fuses.

Specifically designed for use with high-flow in-tank fuel pumps, this kit supplies maximum voltage and steady current directly from your battery to your pump. Featuring an 80-inch pre-wired relay socket with 12-gauge power wire, a heavy-duty 20-amp relay, and a splash/dustproof auto-resetting circuit breaker, this complete kit provides thermal overload protection and seamless integration into race or street setups.

Best Uses

1. High-Flow In-Tank Fuel Pumps: Ideal for supporting high-performance pumps (such as AEM 340LPH/400LPH or Walbro 255/450 pumps) that require dedicated, stable voltage.
2. Auxiliary Electric Fuel Pumps: Essential for external or surge-tank fuel pump configurations in high-horsepower setups.
3. Medium-Draw Automotive Electronics: Perfect for wiring auxiliary electric cooling fans, intercooler water pumps, and transmission coolers demanding up to 20 continuous amps.
4. Custom & Track Wiring Projects: Excellent for standalone engine management conversions, race cars, or kit-car builds requiring dedicated fused power circuits.

 Features

1. Pre-Wired 80-Inch Harness: Includes pre-wired relay receptacles with generously long 80" 12-gauge power wire for flexible mounting locations across any chassis.
2. Auto-Reset Circuit Breaker: Features an integrated, splash- and dustproof auto-resetting 20-amp circuit breaker with a convenient mounting tab.
3. Heavy-Duty 20A Relay: High-quality 20-amp relay ensures continuous duty performance under tough race and street conditions.
4. Heavy-Gauge Ground Lead: Equipped with an 80-inch, 10-gauge high-current ground wire to ensure maximum circuit safety and low electrical resistance.
5. Complete Installation Package: Comes ready to install out of the box, complete with 10–12 gauge ring terminals, red butt connectors, and essential mounting hardware.

Benefits

1. Maximizes Equipment Flow & Efficiency: Delivers uncompromised voltage and current to your fuel pump or accessories, ensuring they operate at their full rated performance levels.
2. Protects Factory Electronics: Prevents damage to OEM wiring, switches, and relays by drawing heavy loads directly from the battery rather than through factory harnesses.
3. Enhanced Safety & Circuit Protection: The auto-reset circuit breaker safeguards your vehicle from electrical shorts without forcing you to manually replace blown fuses on the track or road.
4. Simplifies Clean Installation: Pre-wired sockets, crimp terminals, and generous wire lengths eliminate guesswork and save significant installation time.
5. Weather-Resistant Durability: Splashproof and dustproof circuit components ensure consistent operation even in exposed engine bay environments.
