This wiring provision option consists of one 16 gauge (1.0 mm²) wire connected to an alternating signal flasher located underneath the instrument panel on the passenger's side. Five feet (1.5 m) of extra wire from the flasher is routed from underneath the instrument panel to an area behind the grille. All four wires have 12 inches (30 cm) of extra wire in a coil behind the grille. Grille lamps and the speaker are not included. The flasher is not included when SEO 6J7 is ordered without SEO 6J3.

The SEO 6J3 wiring provision also includes control wiring for the SEO 6J7 exterior lamps emergency flashing system. A dark green/red 18 gauge (0.8 mm²) headlamps flasher module control wire activates the flashing system when 12-volts are applied.

When SEO 6J7 is installed without SEO 6J3, only the dark green red control wire is provided for connection to customer-furnished 12-volt switching to turn the emergency flashing system on or off.
