1969 gmc c10 lights not working

[Cavinessh]

The truck that I'm working on is my late father-in-laws truck and has been setting for 10+ years and I'm trying to get it back on the road. It just made me sick to just see it sit in the woods. On to the problem at hand, I can get the passenger side parking light to work and the drivers side tail light to work also. The dash lights will work but are very dim and the inside dome light will work also. The turn signals will not work but I can get the Hazzard lights to work on dashboard only. I'm getting fire to fuse box but not the headlight plug-ins...any help would be greatly appreciated
