Yes if your ’03 Yukon XL has the factory tow package.
Details:
-
Pollak 11-916 is the GM-style 7-way RV blade bumper socket that twists/locks into the factory bumper opening and plugs into the OEM rear harness.
-
It fits GM full-size trucks/SUVs from that era (incl. 2003 GMC Yukon XL) when the factory tow wiring is present.
What to check on your Yukon XL:
-
Bumper opening: Round GM twist-lock opening at the driver-side bumper corner.
-
Factory plug behind it: A GM/Delphi plug (usually a rectangular/oval 7-wire connector) on the frame harness to snap into the back of the socket.
