Bulkhead connector

Just bought and installed a new bulkhead unit (the one in the firewall) from Dante. it was a spot on reproduction. The connectors were easy to clean and move over, except for the two main wires which were melted into the old bulkhead connector. One fused with the adjacent wire to the backup lights so that every time I turned the key on I had backup lights on all the time. That's what I got from a 95 amp alternator and an intermittent voltage regulator problem. for some reason the product is not on their web site but somebody here clued me in and I called to get it.
