Introducing our 3D Printed 3 Hole Universal Bulkhead, specifically designed for Holley EFI Terminator X and X Max ECUs and wiring harness. This versatile bulkhead also works seamlessly with Dominator and HP harnesses. The bulkhead features three precisely measured holes: 27mm, 18mm, and 13mm, allowing for efficient cable management and installation.
The bulkhead consists of four pieces and requires cutting a single 2.75 inch hole for installation. Once installed, the bulkhead bolts together, securely sandwiching the firewall to provide a durable and reliable connection.
