Re: Wiring Help Please - What's it for

The dimmer is easy.

Single Black with White tracer terminated with a single Female Packard 56 terminal is not in any of the 79 or 80 wiring diagrams.
The insulation means it probably was routed near something that could damage unprotected wire.

Can you find that wire color elsewhere in the harness and test for continuity?
Maybe follow it?
