I’m going to try to attach a photo of my wire bundle, taken as I was installing the Tekonsha unit 5 months ago. I believe you can see the blue/violet wire in the center of the bundle on the back side. I cut the cloth with an Xacto “hobby knife” with pointy blade, and a pair of pointy scissors. You have already exposed a much larger working area than I was able to do. I couldn’t/didn’t remove the side panel, so I was working in very tight quarters. Would stick my phone back there to take a picture, then make the next step. Very frustrating as I recall!
Sorry, I should have loaded the full-res image, where the blue/violet wire would be more clear. It is the one in the center of the bundle in the image, showing through from the back side. Not very convenient - like making this post from my phone!
