Hey everybody, how's it going Today, we're gonna be going over and showing you how to install the Curt protective MultiPro and Multi-Flex tailgate sensor here on our 2019 GMC Sierra 1500. So, this system here has sort of a dual purpose, if you will. Number one, we're gonna get a nice protective hitch cover here for the receiver tube on our truck to keep the inside of the trailer hitch free of any rust. Therefore, we don't have to worry about any troubles or headaches inserting our accessories. It also looks pretty nice, too, to have that black cover on there. However, the main purpose of this kit here is gonna serve to protect our tailgate.
So, I'm sure you guys are aware of on the newer GMC and Chevy trucks. Some of these models come with the MultiPro or the Multi-Flex tailgate system, depending on which model you have, GMC or Chevy. They both call these things, the MultiPro or the Multi-Flex. They are, however, the same tailgate. Now, this is a great feature for your truck, I really like those tailgates.
But there is one big problem a lot of consumers have come to know. And that's damage to the inner part of their tailgate, while lowering it, while they have a hitch-mounted accessory in place. Now, I know what you guys are thinking, you guys aren't gonna be the ones that are gonna do this. You're not gonna make that mistake by lowering the inner section of the tailgate with your ball mount in the trailer hitch there. But it's actually a little bit more common.
We hear of countless stories, horror stories, if you will, of people damaging their tailgate by lowering the center section while they have a ball mount in place. Let's face it guys, this is a several-thousand-dollar mistake, it's not one you guys wanna make yourselves. Therefore, you're definitely gonna wanna look into this sensor system. So, basically, how this works is there's actually gonna be a sensor built into our cover here. And what this sensor does is it cuts the circuit to the inner portion of our tailgate while it's opened.
So, right now, the sensor is closed, therefore, our circuit is still active. So, if we go ahead, lower the tailgate, like we would normally. There's the main tailgate. And here is the center section. You can see, it releases, no problem, no issues whatsoever and normal functionality. So now, we've got our ball mount in there and we're ready to tow, but we need to get something out of our truck bed first that we forgot. So, let's go ahead, open up our tailgate here. Open up the main tailgate. Something's a little bit further back in there that I can't quite reach with the main tailgate down, so I'm gonna try to lower the center section here, so I can reach back a little bit further. But as we can see here, the sensor system is overriding the tailgate functionality here on our vehicle, and I can't lower that center section. And that's great because if I we're to lower this, it would certainly come in contact with our hitch ball here, damaging our tailgate, costing us thousands in repairs. So, today, we have the sensor installed on a 1500, half-ton pickup. However, if you have larger three-quarter or even the one-ton pickups with the 2 1/2-inch receiver tube opening, there is an option here for that larger receiver tube opening. Therefore, no matter if you have the two-inch or 2 1/2-inch trailer hitch, you're gonna have an option here with this sensor system to prevent damage to your tailgate. This kit here, assuming that we have the correct size for our trailer hitch, is gonna work with 2019 and up GMC Sierra and Chevy Silverado pickups. So, in regards to installation, this one is very simple. It's definitely something I encourage you guys to try at home by yourselves. You really only need a couple of common hand tools to be able to get this job done. We don't have to worry about lifting the vehicle. And best of all, everything is plug and play. There's no splicing or alterations needed to your truck here, so it can remain completely stock and factory without voiding any warranties. Let's go ahead and walk you through this entire process step by step now. So, to start your installation here, you're gonna be taking the upper half of your cover. You're gonna be placing that over the top of the receiver tube here. You'll notice that the collar on the receiver tube is gonna fit right into the indentation here of the cover. So, we're just gonna place tha

This is a great video. GM should be putting this on all their trucks with the multi-pro tailgate. For installation, you do not need to remove the connector on the outside latch. Just move it out of the way and then remove the inside latch. Also route the wires along the tailgate before you connect to the latch assembly.

Thank you for sharing your feedback and tips with us and others. This would be a nice feature from the factory but it's also a great add on option to protect your tailgate!

I love the product but there is one issue that Curt has not thought of or maybe they have. I have a truck camper so when I want to remove the tailgate I have to unplug the power mod and camera modules under the truck and then I am good to remove the tailgate. With this products "plug and play" adapter connecting inside the tailgate I will have to continually take the cover off my tailgate to access the connection. Maybe someone could tell Curt to make wires in the tailgate longer so the sensor can be plugged in under the vehicle no different then the tailgate wiring harnesses. They could also sell a 6ft extension harness with the proper adapter ends so it could be plugged in under the truck. Maybe they do have such an adapter if not big miss on their part but an opportunity for etrailer.
