New brain teaser -
My rear tailgate harness plug is not sitting flush to the metal frame anymore, and as far as I can tell that comprises the waterproof/watertight design. It appears that this is due to my aftermarket backup cam install from a couple years ago. Best Buy did the install, which was my first mistake and I've had to fix almost everything they touched since the install. Anyway - this is causing the plug to pop up just a bit, and I need to get it to sit back down as water is running through the gap, into the ceiling cargo trim, and dripping down into the cargo flooring and bumper/frame cavities. Finally figured out the issue after being haunted by it for most the winter.
So looking for input on the best way to fix this, I have 2 thoughts/ideas currently:
1. waterproof silicone around the harness plug/tailgate frame connection point, and call it good. Feels like the easy button, but unsure if thats a permanent solution?
2. figure out how to get a few more inches of backup cam wire and get it running correctly through the harness, so its not putting pressure on the harness plug and allowing water to run through. Potentially also silicone this after adjusting/fixing, just for a bulletproofing measure?
Also just for a best practice double check, Best Buy ran the reverse cam cord down the driver side thresholds, up and over the rear left rear well, through the jack compartment, and then up the rear driver's side column to the point pictured. Seems to be about the best you can do running that wire but if there are better ways that would be good to know to get myself some wire back to further resolve this problem. As it currently sits I think they used every inch of the cord which is why its pulling so tight against the harness plug.
