Can anyone tell me what wire this is?
Originally a 383 car. Now has a 440 with msd eginition. There is no washer bottle in car now. These there are 3 wires not being used. Cheers

The double ended spade plug looks like a ballast resistor plug.
Ring terminal with black insulator next to it looks like a coil wire.
other maybe a horn wire?

Check the wiring diagrams. The purple one on the right is for the backup light switch in the 4 speed trans. On the left picture (top to bottom) heater fan power, ballast resistor, coil, washer pump, horn relay. That should be the order, but chase the wires down in the manual.
