turn sigal wiring 1970 ford f100

[huckaby1966]

1970 Ford I am having trouble turn signals and break lights. I wired them off of Fordifications Website and they work and then they quit working. The fellow before me had cut the plugs off and wired it direct with no plug, so I have a mess to begin with. The truck sat in the timber in MIssouri for the last 18 years and was a basket case. I have got it up and running new motor/everything, but this brake light turn signal thing has got me puzzled. They work on the front, but not on the back. The truck belonged to a funeral home where is was bought new in my home town and they had used it for a casket truck. Then the funeral homes grandson made a camper out of it for black powder shoots. It only has 49,975 original miles and I am getting aggrevated with it. Can somebody please help me with this wiring. I will post before and after picks hopefully someone can help me.

Thanks,
