Brake Lights and Turn Signals not working

Yep.
The other place to check is do a search here for the pdf's 1969383s made. They are copies of the factory diagrams but with layers that can be turned on and off. Also on some I beleive he made small corrections.

if you find some of the schematics posted that I've done, just be careful to note any differences between '67 and '69. There might be small changes in how the hazzard/brake light/parking/turn signals shared fuses or the exact routing.
