Hello Todd,

I am very sorry the install is not going more smoothly for you on the Redarc # RED52VR, seems like this is an ongoing issue with the Trailblazer and finding the brake wiring. Any chance you are close to Wentzville, MO? We would love to do the install for you so we can have the footage on our site. I am not really surprised that your dealership was not much help, they are better at selling cars than helping you with the one you already bought. I turned this into it's own question so I can attach some images that I found from an install so you can see just how hidden this wiring is. This is showing that it is all the way to the left after you remove the kick panel. I attached an image showing the knub of wiring, and also what it looks like after you remove he black protector.

Please let me know how it works out, would like to put this game of "Where's Waldo" to rest =)

@Todd I am very sorry to hear that it was not there. I have a couple of people here I am going to reach out to today to see if they can solve the mystery. If I find out anything at all I will let you know. If it does come down to you going to the service department, please let me know where it is. If you have any questions in the meantime, please let me know.
