Wiring harnesses can rot with age and if your classic Chevrolet has been sitting in a barn for a few decades, it might have attracted mice and squirrels. You might as well replace all the wiring harnesses rather than try to patch parts. A new harness is also better than risking a fire with an old one. We carry wiring harnesses for the 1955, 1956 and 1957 Chevrolet. Select from clock harnesses, glove box wiring, lights and even the complete wiring kit today.
