turn signals, Interior and exterior lights

[Foster1]

I have a 1957 Thunderbird whose lights were working before it was stored for the winter.I found the wire in the trunk and jiggled it, the lights came on but if I slam the door or would hit a bump they turn off so I am sure it is just the wire loose. I don't know where to look for a fuse (?) for the others.I am not familiar with any of this , my husband passed away in Feb.,he was the mechanic.I am hoping someone can give me the information so I can get the car on the road. Thanking you in advance!!
