Pursuit High Beam Flasher Wiring Diagram - Tridon EL13A Wig-Wag Headlight Mod

This document is a simple hand-drawn (CAD-style) wiring diagram showing how to add a 'pursuit'-style alternating high beam flasher circuit to a vehicle's headlights. The circuit uses a Tridon EL13A flasher unit as the flashing element. Two switches feed the circuit: a dedicated PURSUIT SWITCH (which routes power through the flasher to alternate the lamps) and the vehicle's existing HIGH BEAM SWITCH (which feeds the lamps normally). Both high beam lamps are drawn at the top of the diagram, each fed through a diode. A callout instructs the builder to 'ADD 6 AMP DIODE TO EACH HIGH BEAM FEED' — the diodes isolate the two feed paths so the flasher can pulse the lamps without back-feeding the normal high beam circuit, and vice versa. From this diagram a reader can learn the basic parts list (Tridon EL13A flasher, one toggle/pursuit switch, and 6-amp diodes) and the general wiring topology needed to make factory high beams wig-wag when the pursuit switch is engaged while retaining normal high beam operation. The diagram contains no wire colors, gauge specifications, fuse ratings, connector pin identifications, or vehicle-specific year/model information.
