Brake switch jumper wire, 4 inch long extension. Bridges the under dash wiring harness and the brake light switch. Not used on many cars, we suspect that it was used on the assembly line when the brake switch plug didn't reach the brake switch. Adding one of these jumpers, saved time from re-routing the under dash wiring harness. This jumper can also be used to repair bad stop light connectors on 1967-70 Cougars and Mustangs (and other Fords) by cutting off the male end and splicing it...

The paper tags are missing from these harnesses, but we are pretty sure that they begin with C8OA-19A041.One of our customers says that...
