Troubles with Turn Signals 67 Barracuda

Took me all summer to get to it but I just replaced the turn signal switch in the steering wheel. @67Dart273 you had said potentially something crazy could be going on in the switch. Well two wires (red and white) had insulation cracked off at the same spot (see pic). Even if the signal wasn't actuated do you think this could have caused some kind of short or arcing? I drove it for about a half hour with no problems with the new switch. Still don't have 100% confidence though. Hoping someone's electrical expertise here can confirm if this could have indeed been the culprit. Thanks!
