I’ve got a ‘66 mustang that was built in May. From what I’ve read, these post March 66’s should have a plug and play wiring harness for emergency flashers, but looking under the glove box I don’t see any harness. Just a silver cylinder with a blue and red wire and a white w/ red stripe. Do I need to buy the wiring harness to install an emergency flasher switch and where do I plug it in??
