I am sorry to hear you are having a hard time finding the correct cold side stop light switch wire on your 2010 GMC Canyon.

When we installed the Tekonsha Primus IQ # TK90160 on a similar 2005 Colorado we found the the cold side of the stop light switch wire was the light blue wire as you can see at the 8:00 minute mark of the included video.

I recommend using a circuit tester like # PTW2993 to verify that this wire is still the same on your 2010 model year.
