Modifying your muscle car? Building a street rod with one of our harnesses? Your turn signal switch is safe!

All of our Classic Update and universal harnesses use a ‘69 – ‘76 GM steering column connector. This allows our kits to mate with many popular aftermarket and frequently swapped factory parts.

At this point, those of you familiar with what happens when you try to combine a straight line with a curve will probably begin to wonder how we accommodate the original switch with the later (flat) GM connector.

Fortunately, the swap is straightforward. Each Classic Update or universal harness includes an adaptor and mating terminals (center, below) used to plug into the pre-wired dash (below, right) connector.

Simply cut the wires leading into your original curved connector, crimp the replacement terminals on the newly bare wires, and you’re ready to plug in! Vehicle-specific kits include instructions to match your switch to the American Autowire dash.

By supplying all the parts needed to build the connector, we eliminate the need to splice and solder wires into what can be one of the more complex electrical areas of a vintage car. It also eliminates the need for hand signals if your turn signals stop working because of a damaged plug or poor connection at the column!
