Starting to research these, many of them have part numbers imprinted. I think that these exist because:
- The suppliers shorted the wiring in the harnesses
- Wiring routed incorrectly during installation
Top wire is a jumper for the 1969-70 heater fan switch.
Second wire is a jumper for the brake light switch.
I have forgotten what the third jumper is for.
These jumper wires aren't real common. These have all come from Cougars 1967-73 Dearborn, and 1968-69 San Jose. I have no way of knowing exactly which specific car any of these came from. Just found in our tangle of wiring, removed from car over the passed 23 years.
