CURT 55319 is a vehicle-specific 4-way flat trailer wiring connector for select 1990s Chevrolet and GMC Suburban, Blazer, Tahoe and Yukon vehicles, plus manufacturer-listed 1999–2000 Cadillac Escalade and 2000 GMC Yukon XL 1500. The custom wiring harness plugs into compatible tow-vehicle wiring to carry running, brake and turn-light signals. The manufacturer's description also names Yukon XL 2500, but its detailed fitment table is inconsistent; verify that application directly before purchase. Match the model, year and connector before ordering.
