Question about new fuse box and Amp meter bypass

"If I live long enough" to get my car running again, there IS NO bulkhead connector. I made a simple sheet metal plug the same size as the old connector, and it even snaps into the hole with the factory gaskets and retainer clips. Just punch a hole with a large grommet for the wiring to run through. If you need to remove it for some reason, all the harness should pull through the hole with the plate unsnapped into the interior
