Correct plug for your 67-71 AM- FM radio, or 8-track... Often these have been cut from the main loom to install an after market radio.The 1972 model used the same plug, but the wires are not in the same spots, go figure! These are speaker wires not power wires.
The color codes are:
White right cowl speaker.
Orange left cowl speaker.
Speaker blue / black ground.
Power "not this listing."
Blue / red stripe, radio light.
Yellow / black stripe, power in for radio.
