Parking Lights won't work, but fuse isn't blown..

My '86 truck does this from time to time. I found two things, a corroded fuse, and a loose connection where the large plug bolts to the firewall under the hood. I would check those quick. I even replaced the switch, before I found the real problem…

Thank you much, I will check that tomorrow as long as its not pouring down rain. I appreciate it.
