How do you remove the engine wiring harness from the area it enters the firewall behind the distributor on a 1971 Chevelle Malibu? This is the only part of the harness that seems to be attached on the inside under the dash. There has to be a simple way, does anyone know?

The engine harness plugs into the back of the fuse box. there is a 3/8 bolt in the center . unbolt it then unplug it, that's how it comes out,
Good luck!
