Rywire Mil-Spec Connector Plate - Small 3x3in - RY-PLATE-MIL-SMALL

The Mil-spec Connector plate will allow you to use your A.C. (air conditioning) firewall hole as the junction point for your harness in your bay by using the rectangular 3x5 inch version or the square 3x3 version.

This does not include the mil-spec connector itself: the one pictured on image 4 is an example.
