Is there a source for the Male (Engine Side) wire connectors within the main firewall plug? I have two that are deteriorating. Thanks!

I replaced mine with a junkyard block replacing each fuse terminal pin for pin, turned out nice because I found a like-new one. But I've not seen them sold separately, unfortunately.

I don't know for sure but I bet if you called M&H or similar where they MAKE the harnesses, they might be able to hook you up with the connector for one end.

They are available through NAPA (#725444 for 14AWG) and other sources. Known as Packard 56 or GM 56 connector pins. They come in different wire sizes. I have some information posted in my WMB thread (link below) from when I replaced one of the pins in my connector.
