Reference Information

Electrical Wiring Connector, Power Adder Harness Connector, Kit

FAST ECU main connector kits include all main connectors and terminals used when connecting a wiring harness to a FAST ECU/ECM. Environmentally sealed Weatherpack connectors were originally designed to withstand exposure to extreme temperatures, moisture, and harsh engine compartment fluids and chemicals. They are heavily used by OEM automobile/truck, construction, off-road, and farm equipment manufacturers due to their high-quality and excellent fitment.
