'67 Dart GT wiring question

No, I was not aware. Thanks, I'll check it out.
I found the second relay, both test good. I.E. less than an ohm with 0 volts, and they work as they should when 12V is applied.
I then tested the wiring to both relay sockets and neither are seeing any voltage at any time. The only time the signals actually "work" is with the brakes on. Then the turn signal turns off the light as it should. I'm going to re-cover the front seats whenever the materials get here. I'll look deeper into it when the seats are out.
Thanks all for the help.
