How to Install Curt Spectrum Brake Controller on 2011 GMC Yukon with Factory 7-Way Connector
Question:
Hi, I have a 2011 GMC Yukon Denali, with the factory 7 pin connector. Is there a vehicle specific wiring harness available for this, or will I need to modify the wiring ? Thanks,

While there isn't a direct plug for installing the Curt Spectrum Trailer Brake Controller # C51170, there are blunt cut wires under the driver's side dash of your 2011 GMC Yukon that you will connect the Adapter # C51515 to so that connecting the Spectrum is more of a plug-and-play installation.
According to the online owner's manual for your Yukon you will connect the following wires from the adapter to the following wires on your Yukon:
Blue - Dark Blue
Black - Red/Black
White - White
Red - Light Blue/White
I recommend verifying this with a circuit tester like part # PTW2992 and checking you owner's manual to make sure that all of these are correct as well. Once you make sure you know how to correctly splice your wiring together you just need to use butt connectors like part # DW05744-5 to complete the installation.
