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 into the 14401 harness.
Since the factory part seems to fail with the wires overheated,
the wire size was increased to 14 gauge in order to handle the extra current required for the Cougar brake lights.
The L/M and Ford parts catalog specifically calls this part to be used for disc brakes, power or non power.
The 1968 factory assembly manual shows a unique cylindrical stop light switch that as far as we know, was never used. It fits into a bracket at the top of the 1968 non-power brake pedal. We can speculate that perhaps the wire length was shortened to accommodate this switch but not corrected when the original style switch was used instead.
We suppose a number of these harnesses went into production before it was caught.
