Here's a pair of 1966 Barracuda fender turn signal wiring harnesses. These are used to connect the fender turn signals to the headlight/main turn signal harness. Guaranteed to fit 66 Barracudas or if adding the 66 fender turn signals to a 66 Valiant you will need these. They might fit 67-up with fender turn signals but don't know this for sure. $30 shipped from 22657.
