Hello Tom. Our best wiring harness option of the 2024 Cadillac XT4 is the Tekonsha ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT. The Zero Contact Interface (ZCI) harness is great because it uses clamps that go around the wires in your car and detect electrical pulses. So, you can add on a wiring harness without any hardwiring, cutting or splicing of the vehicles wiring. This is something we recommend frequently for nicer vehicles like Cadillac, Audi, BMW or Mercedes-Benz with no custom fit options for wiring. You will find a few of our install videos linked below.
