Pierburg CWA400 Trunk Tank Harness with fuse and relay
This harness is designed to run the CWA400 pump at full speed/voltage. Made with high quality 10-gauge wire along with a properly sized fuse, relay and terminals. The length of this harness is about 4 feet, perfect for trunk tanks.
Early in 2024 Pierburg changed the programming in a manner that makes the pumps stay on even after switched 12 volts is removed. This made the relay necessary.
