Specification:It offers a 1 1/8" hole and a 3/4" hole. The outside dimensions are 3.78" by 2 1/8".P/N:01232023
Installation:This is a two-piece design, where the upper and lower parts are fixed together with middle bolts, and then the bracket is fixed to the car with the remaining four bolts. You can remove the upper part of the bracket, which gives you enough space to install or remove the wires, then you just need to fix them together and reinstall the car bracket bolts.
Unique Design: The wire harness holes on the firewall through the bracket adopt an arc-shaped design, which minimizes the damage caused by friction to the wire harness. Even if used for a long time, it will not cause harm to the wire harness.
Note:Installation requires the base plate to be fixed first
