I just picked up a 2015 GCL with no trailer hitch. Went to Amazon and bought a tubular one for 128.00 (with tax and prime delivery). Took 15 mins to install, so easy, remove 4 existing bolts, (tools needed is a 1/2 racket with a 21 mm socket) and install your new receiver. That's it. The GCL also has the connector underneath the bumper wired. All you need is a "T" connector to go from 7 pin to 4 pin if using a utility trailer for the lights.
Also you need the dealer to program the computer to activate the lights for the plug.
Read the reviews for additional information for the below items on the Amazon site.
BTW it states that this does not fit the 2015, but it does, i already installed it and so have others on the Amazon site.
Parts needed: Curt 13182 Class 3 Trailer Hitch, CURT Manufacturing 55515 T-Connector
Go to curtmfg.com for install instructions for the curt 13182
