is that the old pic of the gauge connector?
im not an expert but i have no idea why you have 2 wires there.
the brake warning light circuit: power starts from instrument panel light circuit through brake warning light bulb then tan wire to gauge connector then tan wire through firewall panel to the brake warning switch on the brake combination valve. if that switch moves it closes the circuit to ground; causing the light bulb in your instrument panel to light up.
cant help you beyond that.

The brake warning light gets it's power from the fuel gauge terminal. The tan wire is a grounding wire to the switch in the proportioning valve by the master cylinder, BUT there is also a wire from the switch in the prop valve to the ignition switch which grounds the prop valve switch when the engine is cranking to check the light bulb. The wires to ground the light during cranking vary with years, some are run from the prop valve switch to the ignition switch and then to the cluster plug, and some are run from the ( two wires on the ignition switch) cluster plug to the prop valve switch and from the cluster plug to the ignition switch. ( two wires on the cluster plug.)
Power for the brake warning light on the gauge cluster Off terminal 3 to the fuel gauge. Purple line.
Light cluster wiring shows two wires off cluster plug terminal 2, one to key switch and one to the Prop valve switch. Ignore the black arrows on the key switch wire 12 gauge brown. It is the power feed wire to the fuse panel for the wipers heater and turn signal switch.
Key switch for 1968 and later with two tan (brown), wires for BW light and two green wires for temperature warning light.
