United Statesharness installation non refreshed silverado YEAR 2020
I did this without prior experience. Did the right door first. It was challenging. When I did the left door it was a little more clear, but still difficult. Biggest challenges are pin identification and re-installation of door jamb plug and weatherproof boot. For someone doing this one time, I think a clearer pin identification is imperative, possibly a measurement from the top of the jamb plug As far as door jamb plug installation goes, possibly a better view of just how the plug disengages/ engages would help. Maybe an exploded view Also the rubber bellows- How does it attach A fuller understanding of it would lessen the chance of damaging the upper plastic latch for the bellows that attaches to the door jamb. If I did this for a living I imagine it would go as easily as it does in the video. I did get the kit in and all my lights are working as they should. So in the final analysis, it's a great product. I appreciate the research that went into creating the harness. It's at a fair price. I would caution those who have pork chops for hands and large arms to find a nimble skinny dude to help with the install.
