FedSig Expansion Module Harness - Tahoe

FedSig Expansion Module Harness - Tahoe

Unleash the full warning potential of your Chevrolet Tahoe PPV with the Federal Signal EXPHARN05 Expansion Module Harness. Connecting the Tahoe's OEM rear lighting directly to the Pathfinder EXPMOD-2 rear expansion module, this plug-and-play harness allows the factory taillights, brake lights, and reverse lights to function as synchronized emergency warning devices. Because it operates on the FS Convergence Network, upfitters can program complex flashing sequences or tactical blackout modes via software, entirely eliminating the need for destructive wire cutting or external flasher modules.
