1965 C20 electrical question

[texasplumr]

Got an issue. I just picked up this truck. Runs great, looks not so good. But the headlights and front running lights or turn signals don't work. The tail lights and turn signals work fine.

I'm thinking it might be in the plug on the firewall. There are two separate plugs since the running lights are in the hood.

Would you more knowledgeable folks concur that this would be a good place to start? I don't have a problem building a complete new harness if that's what it takes. I just don't want to if I don't have to.

It's the only thing keeping me from getting an inspection sticker. In Texas we have to get inspected every year.

I was going to post pics this weekend but haven't figured it out. I moved them to Photobucket so that should make it easier.

Thanks for the help! I'm just hoping someone on here may have had this problem and save me a step or two.

Thanks!
