that diagram is the older trucks that brown/white tracer is the one for the generator dummy light on the dash, it gives the light a ground when you turn the key to the on position before you start.. same as the brake oil press and temp dummy lights (tan/green and blue at the key connector on the 70's). The brown/ white tracer he's talking about is only at the firewall connector but doesn't travel up the harness to the dash.
