You need the center console out. Which means you need the trim piece above it out first. You will then be able to see the underside of the DCM and the wires in the rear of it will be accessible. To work with the wire harnesses plugged into the DCM: You need the glove box out for visibility. The passenger inner kick panel should also come out because it's a great area to have a flash light pointing directly up and lighting up the work area. And that's it. Using a pick tool (google "curved pick tool mechanic" without the quotes) you can stick your head in through the glove box opening to see the back of the DCM while your hand comes in through the center console area with the tool to unplug whatever wire harnesses you desire. If you decide to do anything with the wire harnesses make sure to secure them tightly so you do not introduce any rattles to your dash area. You can put some felt tape around that area and zip tie the floating harnesses to the main wire run.
Amazon item B0BPSB41CW. Coverado seat covers purchased about a year and a half ago. They're holding up alright. I think I've seen a small stitch come loose somewhere but overall they're holding. I also used a seam ripper to remove the emblems on the seat back covers. No logos for me. My car does not have power seats so I have the manual adjust handles. Those seem to interfere with the fit slightly. But again, overall they work well. They're just not great. I'm sure other covers have better fitment for my seat bottoms.
