Pierburg CWA400 Trunk Tank Harness with Fuse & Relay
Power your CWA400 water pump reliably and safely with Dedicated Motorsports’ premium trunk tank harness.
This high-performance wiring harness is specifically designed to run the Pierburg CWA400 intercooler pump at full speed and voltage, ensuring maximum cooling efficiency for your setup. Built with high-quality 10-gauge wire, it includes a properly rated fuse, relay, and premium terminals for long-lasting durability and optimal electrical performance.
• Ideal 4-foot length for trunk-mounted intercooler tanks
• Designed for full voltage operation of the CWA400 pump
• Includes relay to address Pierburg’s 2024 software change (pump remains on after 12V is removed)
• Clean, simple install for street and race applications
Note: As of early 2024, Pierburg revised the CWA400’s programming to continue operating even after switched 12V is removed—this harness solves that issue with an integrated relay for proper shut-off.
