I want to run several wires through the fire wall pass through connector (C-100). I thought that the connector used the same terminals as my 73 Buick, which are Packard 56 style, but in the one remaining large unused cavity, the terminals will not go in. There are many unused cavities that are smaller and appear to be the same style, but I am unable to locate the correct terminals. I don't want to destroy the current terminals or connector cavities removing one terminal to see what it actually looks like. Does anyone know what the terminal part numbers are? The engine compartment side uses male terminals and the dash side uses female terminals. The picture I uploaded is the Packard 56 terminal. Thanks
