1966 V74 Hazard Flasher Kit

[mssl72]

I took a look under my dash tonight to refresh my memory. The wiring that comes off the steering column is a short harness that looks similar to the harness that Lee linked in his reply. The dash harness has the curved connector as part of it and the short harness from the steering column plugs right into it. The flasher plugs in between the dash harness and the steering harness. If you don't have the curved connector as part of your dash harness it may have been modified. Follow the wiring that comes from the steering column and see where it goes.

Here's another page from my assembly manual. It shows the connector as part of the harness (Directional Signal Switch) and are clipped to one of the support bars as I mentioned before.
