Absolutely Perfect Kit except....
Everything in one kit is perfect! It really is a plug and use system. 5 stars. I do wish that there was something for instructions. A few YouTube videos clears up most of it. Took me about an hour and a half for the complete install. I did not order this by part# but I should have asked questions before ordering it. The kick panel cover supplied is a dark brown and my interior is black.

It is brown but barely noticeable on black interior.
The knee bolster and the switch bezel ARE brown. So if your interior is black it will work but the color will be slightly off.I found the part number to the black knee bolster made for the upfitter switches and bought it for $40 from a dealer (I got a great deal) but can be found as high as $100. I still paid less than the $400 that this kit retails for. IMO I was better off just using the brown knee bolster. I just couldn’t find a black bezel that replace the brown trim around the switches. The first photo is the black knee bolster I purchased separately. The second photo is the “brown” knee bolster that comes with the Amazon kit. The last photo is the black knee bolster installed with the brown trim around the aux switches. The photo exaggerates the color contrast, it’s hardly noticeable.

100% OEM
This is 100% OEM and came with everything you would get if you ordered it factory direct.

Doesn’t seem to work
Install was pretty easy after watching u tube videos, unfortunately doesn’t work. When you push the buttons, they light up like they should, but the relays don’t activate, and no power to the 4 wires. I thought maybe bad switches, because I used the black ones that came with truck, unfortunately I switched those out and still nothing. They must have sent out a bad control module/fuse box. Not very happy with this after many times of messing around under dash, off and on for months

It's brown!!!
Caution, this product is dark brown, not black. In some light, it's very noticeable.Overall I'm very pleased. Instructions are worthless, so be sure to watch YouTube videos. Be prepared to spend about 4 hours installing it.

It's Brown
Excellent product easy install. Beware it's Brown in color. If your dash is black like most of the trucks you will need to cut a hole in your existing panel and use the brown button surround panel. Not a major deal breaker but, unexpected. Kit should state this and be available without the useless panel.
