The only items fused on the early Fords are lighting related. A hot wire from the Starter Switch (battery side) connects to one side of the Fuse Holder (the non-fused side). The stud on the Fuse Holder is just used as a connection point. This wire should be a fairly heavy solid Yellow wire. It loops through the ammeter before it connects to the fuse panel stud. Also connected to this same stud is a Yellow wire with Black tracer marks that starts at the Cutout on the Generator. The third wire is a solid Black wire to the Cigar Lighter. And a fourth wire is also a Yellow wire with Black tracer that goes to the Ignition Switch.

The fused side has two wires, a Yellow with Red tracer that goes from the Fuse Panel to the Lighting Switch (at the base of the steering column) and a Black wire with Blue tracer that goes to the Dome Light Switch.

Back to the Ignition Switch, there is the Yellow/Black wire coming in from the Non-fused side of the Fuse Panel Fuse Holder and a Black wire with a Red trace returning from the Ignition Switch to the Ballast Resistor mounted on the Fuse Panel. And then a Black wire with a Green trace going to the Instrument Gauges (Oil Pressure side). The other side of the Ballast Resistor has a solid Red wire that goes to the Coil.

That's about it for the under dash wiring.
