Hello,

I need some help. I got a 1977 Ford F-250 a few months ago off of Facebook Marketplace and have been discovering more and more issues with the wiring.

The main problem is the turn signals don’t work, but the flashers do and I need help figuring out what the cause might be.

So far I’ve:

- Replaced the Turn Signal Switch

- Replaced the flashers

- Checked the fuses

- Traced the wires I can see

What else could be the issues? I’ve heard it could be the grounds, but I’ve been having issues figuring out where they’re located in this truck. Everyone online says something different. Any help would be useful.
