Hi Donald!
We definitely have what you are looking for! I have an option for a 4-Flat and a 7-Way below that are plug and play for your 2024 Cadillac XT5:
4-Flat:
Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C56325
7-Way:
Tekonsha T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # 118276
Do you know if what you are going to be towing will have brakes? The 7-Way will be what you want if it does. The 4-Flat will power all the lights on a small trailer that does not have brakes.
Whichever you end up going with, you will also want to grab some mounting brackets. The No-Drill Mount for Electrical Mounting Bracket - Short # 18140 goes right onto the hitch for an quick and easy install and then you would want the # 18144 for the 4-Flat or the # PK12711U for the 7-Way.
Out of curiosity, what are you going to be towing?
