Topic: Whats this wire for question

[fmr187]

65 convertible. While installing my main harness I found a black w/ blue stripe wire coming out of the harness by the fuse box. The wire ends in a female bullet connector. In looking thru the 65 Electrical Assemble manual I found the wire on pages 8141-1 and 8156-1 but neither drawing shows where it goes. Does anyone have any idea?

Black with a blue stripe should be part of the courtesy light circuit. I think the female bullet plug near the fuse box would be for a rear courtesy light on a fastback.
