Trailer lights are a plug-in job on this one. CURT 56070010 is the four-flat plug harness for the 2004 GMC Sierra 2500, $325.15 CAD, and it clicks into the factory connector so you're not splicing wires behind the bumper.

2004 GMC Sierra 2500 hitch questions
Which trailer hitch fits a 2004 GMC Sierra 2500?
CURT 14332 (Class 4, 2-inch receiver, 10,000 lb), CURT 13339 (Class 3, 2-inch receiver, 8,000 lb), CURT 13322 (Class 3, 2-inch receiver, 6,000 lb), CURT 13332 (Class 3, 2-inch receiver, 6,000 lb), and CURT 15703 (Class 5, 18,000 lb) and more all fit. Pick the class that covers your trailer with room to spare, then check the fit table on the product page for your build.
How much can a 2004 GMC Sierra 2500 tow with this hitch?
The hitch is rated to 10,000 lb gross trailer weight and 1,000 lb tongue weight, or 12,000 lb with a weight-distribution hitch. Your Sierra 2500 has its own tow rating in the owner's manual, and the lower number is your limit. A loaded bike rack counts against tongue weight too.
Do I need a wiring harness for the 2004 GMC Sierra 2500?
If a trailer is going on, yes. Brake and turn signals have to work, and CURT 56070010 plugs into the factory connector so the trailer lights follow the Sierra 2500's. Order it with the hitch and it's one install.
Will it fit my Sierra 2500?
Nearly every build, with a few exceptions. CURT 14332 doesn't fit a Sierra 2500 with a Roll Pan Bumper or Tommy Gate Lift or 10" Drop Bumper. The full fit table is on each product page, so check it before you order.
