Thanks - that looks interesting, I may check that out... I did not get anything installed yet.

Thanks - very helpful. My pickup is similar to picture below. The silver does not leave much space for a hidden black socket. I cannot fit it flush on the black area on either side of the license plate (side plate?) - the tow hooks are in the way. I am going to try installing it on the air deflector as shown near the red mark for this picture, except aiming to do it on the drivers side. If you have any pictures of a similar install from others, feel free to throw one up here. It is getting cold up north, mine is to connect with the engine block heater....so I will probably install it in the next 1-2 days.

I have a 2014 High Country. I bought the NOCO Port plug a while back and just getting around to installing mine. Did you narrow down a spot and install? If so, do you have any pictures? I am thinking of going low - down into the bottom black plastic layer (skid plate) or even the very bottom black plastic (air deflector) - but have not pulled the pickup in to look behind there and see if it will work. Thanks!

Hi Dee Paw - thanks for the reply. I tried the parts diagram but did not get much luck. On the HVAC diagram, it has a filter housing unit that sits above the filter (plastic) but does not show any nuts in the diagram. https://www.gmpartscenter.net/v-2014-chevrolet-silverado-1500--high-country--5-3l-v8-flex/hvac--blower-motor-and-fan I could not find a detailed service manual - does anyone has a good link service manuals / diagrams - especially for HVAC and what sits above - that would be useful?

I was changing the cabin air filter in 2014 Chevy Silverado High Country 5.3 L today (behind glove box) and found a nut lodged in the top of the filter. The nut was on the left top side of the filter. The nut size would use a 10 mm socket and accepts an M8 sized bolt. The nut is flanged with a rubber washer attached on the back also. I looked into the air filter box (limited view) and also around the cowl under the windshield washers (did not remove the cowl...yet). I am guessing it came from above the air filter- not sure if it just fell through the cowl black plastic cover on the wipers, or if it was part of a bracket in the HVAC system or other part. Does anyone know where this nut might have come from?
