Didn't look too hard but didn't need to. Buddy who's sold 67-69 Barracuda parts for 30 years had an extra harness. He'd used it for parts here and there. He cut the wire off I needed and mailed it to me yesterday. We'll splice it in.
If you use the whole bullet from his, make sure that the pins are in the correct holes... They changed the order on some of them from year to year and some models...
