I have a 77: anyone know what the Green/Orange wire on the turn sig goes to? No mention of that one anywhere on the schematics, so far as I can see! It is close to the GL & Gy, which I believe are the turn lights.

I’ve definitely been all over those schematics, which are awesome. Still confused on the solid green wire out of the hazard and the diff between GO(orange) & GR which are not explained. I saw one vague reference in a painless harness hazard switch that says to splice the GO somehow with something that was also confusing, because this GO wire is such a mystery. Here are some shots of what I’m talking about, coming off both switches:

I just got done removing a 7-pin trailer harness and on my 70, the GO goes to drivers rear brake/tail lamp on our rig. I don't have a GR wire, nor 6 pin harness, just 4 pin harness. Hope that helps.

Edit: I just found this link that may help more.

Thank you guys!!

I got em working! Re-did the wiring to clean up potential problems there, rebuilt the hazard switch, which was ridiculously easy, and then found that the hazard flasher in the EZ harness is wired backwards. Fixed that and am off to the races! Now it’s time for the wipers, lol!
