- Use a circuit tester like part # PTW2993 on the wire in the # 11 terminal on the black BCM connector, as shown in the diagram I provided. The wire colors can vary during a production run, which is why we typically recommend that folks wire by function, not by wire color.
As an alternate method, you can use a fuse tap like part # F2526 on the CHMSL (center high mounted stop lamp) fuse in the fuse box. The lid of the fuse box should have a legend that will tell you which fuse location...

view full answer... - Leaving Fascia In Place to Install CURT Class II Part # C12291 on 2010 GMC Terrain
- I agree, the completed installation would look much better if that piece of fascia was left in place for the receiver to pass through.
The problem is that the bottom of the receiver (once the hitch is installed) is pretty close to the bottom of the removable piece. Once the hole is cut, most of if not all of the fascia below the receiver would have to be removed. Take a look at the install video for the CURT receiver you referenced. At the :11 mark, you see a pretty good shot of how the...
