How to remove connectors from bulkhead

I Hope everyone is staying safe and healthy,
I work in grocery and have been working my butt
off this last month, so I have not looked at the wiring
connector issue, until today.
I could not get the end out of the bulkhead connector
no matter what tool I used, so I took the other 6 out in,
like 2 minutes with no problem, the fusible link blade end
was put in opposite to all the others from the factory, a magnifying
glass helped me figure that out.
it seemed to jam it in and I had to sort of dig the tangs out of the
plastic, finally got it and yes there was blood from the mini screwdriver
meeting my hand, now I can replace the fusible link, still looking for an NOS one.
Thanks for all the help and input
