Mustang Turn Signal Wiring

Brake and turn signal power goes through the turn signal switch, since the rear brake lights and turn signals use the same filament in the bulb (the thicker filament). You need a voltmeter, so you can start at one end and see, where the voltage stops as you go down the line, this is where a wiring diagram with the colors of the wires comes in.. %PDF-1.5 %µµµµ 1 0 obj >>> endobj 2 0 obj > endobj 3 0 obj >/ExtGState >/XObject >/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0.

The one advantage they have over the "simplified" schematics from the 7173Mustangs version (which is a nice set of schematics) is that the Forel schematics include the locations of all electrical connectors, splices, and grounds, as well as an image of each connector.
