Need some turn signal school

You didnt say what year and model. I believe Allpar.com has wiring schematics for some cars that you can download. See if you can get those and a DVM and start tracing the signals. Google it if Allpar doesn't have it. If its a 68 or 69 Dart I have that one. Does it have the original harness because that will help a lot tracing this stuff out.
It's a 1973 duster and I'm pretty sure it was a slant six air conditioning car automatic on the column. yes I've been a bit of an advocate for finding the schematics online and just having one of The Office Depot's making a copy. And I actually have one in color. I've been taking a little time to get familiar with it but haven't got the time to get to the car and make a specific shot at this. I was hoping to gather a little bit of the do's and don'ts and don't try this and definitely try this kind of stuff. let me get into it here over the next couple days and I'll have some more specific questions hopefully. Thank you so much for your response.
