Dress up you engine bay and ditch the cheap rubber grommet on your PSI style wiring harness. Designed to snugly fit around the harness and rounded smooth edges for chaffing protection. 2 piece design for ease of install and is able to be added to harnesses that are already installed using the commonly used 2 inch hole size in the firewall. Center hole is 1.2 inch diameter. This will also fit the engine only harness on the Terminator X.
