On my diagrams, the tan wires from the brake proportioning valve (and the charge light when equipped) connects to the brown/white wire at the firewall connector. My diagrams are in a large GM issued book. The diagrams unfold from this book and are large enough to be easily read.. I was given these books when I attended a GM training school in Houston back in the late '70s-early '80s..

Although I don't recall ever seeing the tan wires actually connected to the ignition switch plug, connecting to either end of the brown/white wire doesn't affect the function of the circuit. If you guys are following my posts closely, you'll see where I suggested the OP do a test by temporarily connecting his "ghost wire" to the brown/white wire at the switch. it appears I owe zosoppp an apology.
