Headlights, brakelights, heater, and gauges all dead?

The cluster is long gone, its just autometer gauges in an aluminum face.
the ammeter is also long gone but i will pull the gauges out in the am and look around.
how dose one disconnect the bulkhead connector? i have tried before and just gave up..

also isint there a way to bypass the fusable link in the bulkhead?

Thanks again, I realy.need to get this fixed so I can drive on the street.....
