How to Install a Trailer Connector Socket on a 2013 Chevrolet Silverado


Today on our 2013 Chevrolet Silverado we're going to show you how to install the Hopkins Pollak 7 and 4-pole trailer connector socket with mounting bracket. This is the vehicle side. Part number is HM40975. Here's what the line looks like once you get it installed. Really nice, clean setup. We've got our 4-pole on this side. Our 7-pole is going to be on this side.

It's going to eliminate the need for the adapter that we'll have. Whatever trailer we back up to, whether it's 4-pole, 7-pole, we'll have it right there. With the 7-pole option over here, if you did have a brake controller or if you had a 12-volt power router 00:38 running to the back, if your backup lamps we're tied into it, any of those things you'll have great power to the back here through those so you can operate all those other items, plus having just your simple 4-pole connector which you're going to see in a lot of your smaller utility trailers, maybe bike racks or cargo carriers if they're going to come up and cover your lights. Really very adaptable. A lot of different uses that are out there available for it. I like the spring-loaded doors.

They close down and seal off our plugs to keep the corrosion, dirt and debris, stuff like that out. Each one of them has a rubber gasket that's here on the backside. That gasket provides a seal around there and is going to help to keep that going for a long time. This pin in here and the springs are a stainless steel, so those are also going to resist corrosion. We're not going to have to worry about a bunch of rust and stuff like that here in the rear of our truck. Now we're going to start our installation by mounting our bracket onto our hitch.

Some hitches are going to have a bracket that's already there welded on to give you your mounting location. Some are going to have just a smooth tube like we've got here. With this one having the smooth tube, we've added a bracket. It's called the short bracket. Basically it's just a band clamp that goes around.

As you can see, it's going to give us a nice sturdy connection point. We'll now bring in the bracket that's going to come with our wiring, also the self-tapping screws. We'll fasten those right into the already existing holes that are in the bottom of that short bracket. Now we'll bring our plug end in, clip it right into our bracket. You can see it clips right in almost like it was made for it. Then we can reach right up under our bumper here on the backside of the factory plug that's up here and pull that wiring out. Now right up here on the top there's a little tab that we want to push down. We'll wiggle it on off. There we go. We've got this little pull tab right here. We want to pull that out. We'll just rotate that plug, be able to slide it right out. Now we're going to use just a little bit of dielectric grease right down in that connector. I'm just going to bring that up, slide it right onto the back of our connector. You want to hear it click. Then we'll push and pull on it, make sure everything's nice and secure. Then that wiring, we've got any excess we can just zip tie it up. That looks good, though. I don't think we'll have any issues. Gives enough slack there so it's not pulled real tight. Looks great. Now we're going to run through a test, check out all of our lights on both the 7-pole side and the 4-pole side to make sure everything is working properly. The first one we're going to test is going to be our clearance lights. We'll have him turn the lights on. This should light up with a solid signal. That's perfect. The next test we'll do is for our left turn signal. We'll turn the blinker on. We should get a flashing light right here. Now our right turn signal will be the far light. Great. Now when they stand on the brakes, we should have constant signal from both this one and that one. Perfect. We know our 7-pole is working fine. The customer doesn't have a 12-volt wire hooked up or a brake controller or anything like that, so our other circuits won't need to be tested. Now let's check out our 4-pole side. We're going to find a suitable ground. Typically we test our ground right here, but we can't get a tester on it, so now we'll have the running lights on. That should give us a constant signal from the second metal connection from the top. Perfect. The next one is going to be our left blinker, which should give us a flashing signal from the second from the bottom. Now our right blinker should give use same signal from the one at the very bottom. Now our breaks should give us a constant signal from both the one at the bottom and the one at the second from the bottom. Everything is working great. We're ready to head down the road. Now with everything working properly, that's going to complete today's installation of the Hopkins 7 and 4-pole trailer connector socket with the mounting bracket, part number HM40975, on our 2013 Chevrolet Silverado. .
