Adding sensors or accessories to your Holley EFI, Terminator X, or Sniper EFI system? Don’t cut or splice your main wiring harness. The Holley EFI Power Tap is a factory-built solution that gives you clean access to 12V switched power, 5V reference, chassis ground, and sensor ground, all without hacking into your harness.

The Power Tap makes it easy to wire in flex fuel sensors, dome pressure sensors, alternator exciter wires, and other EFI accessories while keeping your install clean, reliable, and factory-looking. Designed for low-current devices or relay triggers, it helps reduce electrical noise, voltage drop, and future troubleshooting headaches.

If you want a professional EFI install that works right the first time, the Power Tap is the way to go. Learn more about Holley EFI systems at Holley.com.
