Video Transcript for Trailer Wiring Harness Installation - 2005 Chevrolet Silverado
Today on our 2005 Chevrolet Silverado crew cab, we're going to install part number 30955. This is a replacement multi-tow 7-way and 4-way trailer connector. We're going to replace the original 7-pole connector That came with the vehicle. This is how it came to us, so you can see that the connector has seen better days. To remove our 7-pole connector, there's a tab right here that we push down and pull out. Sometimes there may be a little gray tab or a lock that fits around this.
You just push down in the center of it and just push it out of the way, then put it back when you're done. We don't have that one, so we'll just push down on this tab and pull it apart. This is our new part that's going to replace the OEM connector. This will simply just plug right back in, like this. However, we're going to take this and route it down towards the bottom of our hitch, toward our pre-existing mounting bracket. This is the bracket that comes with the part.
However, we're going to use the pre-existing one. A good location for this if you wanted to install it, would be right here. It does come with the hardware to install the bracket. However, self-tacking screws will work best in this application here. Let's go ahead and route our wire harness down.
Before we add our new connector, we'll go ahead and put some dilectic grease on the contacts to help protect them. We're using part number 11755. Let's go ahead and route this through our bracket. We'll go ahead and make our connection. We'll just push the two together, make sure they line up OK, and squeeze them until they click. Now we'll use the hardware that comes with the kit, to attach our 7-pole to the bracket.
With our hardware loosely assembled, we'll go ahead and tighten it down, using a flat-blade screw driver. Typically, this star washer on the back will give enough grip; we don't need a wrench. If you do, a 3/8 will work just fine. We'll go ahead and route our wire harness up and out of the way, make sure it's safe and secure with some zip ties. Zip ties don't come with the kit, so you might want to go ahead and get extra long zip ties to go around the hitch. In just a few minutes we've got a new 7-pole connector plus a 4-pole connector installed on our truck. That will do it for our replacement multi-tow 7-way and 4-way trailer connector on our 2005 Chevrolet Silverado crew cab. .

Perfect! I used this on a single cab Chevy Silverado 1500. Plugged into factory trailer lights near spare tire, mounted it up, plugged in trailer and everything worked just like it should. My truck does not have a spare tire so I removed the spare tire keyhole mount and cut some of the bumper to fit the adapter. My truck did not require a ECM/PCM flash of any kind, although I hear some vehicles may have to.

Ordered this because I thought my old one was not working right...so I replaced it..still had the same problem so it had to be something else...but this is a great item has both the 4 flat and 7 way... That's awesome. I figured it out.. had to chase some wires...was not getting full 12 volts to the trailer hook up.. had to make full connection for brake controller

Cathy T. was very good help. She set me up with the correct parts for our 2001 Chevy so we can have a 7 prong plug in at the bumper and in the box. We got rid of the cobbled up mess that started giving us trouble and now everything works great. The plug and play took me about 1 1/2 hours to complete. We will do business again if needed. Thanks again Cathy T. and etrailer!

I installed this today. Took around 90 minutes but part of that was learning how to get the spare out of the way. I drilled two holes in the bottom of the bumper because of where I wanted the connector to be placed. All necessary hardware came with the unit. This was very easy to do after watching etrailer's How To video. Good job guys, great product.

The male connect was not a standard 7 pin connector, I'm not sure what it was, didn't match up with what I had at any rate. I ended up cutting the end off and splicing the wires. Works fine, no issues or complaints with functionality.

The Curt Trailer Hitch Receiver was easy to install and has worked just fine in pulling my several trailers. For the price, an excellent deal. The 7-Way and 4-Way Trailer Wiring Harness Connector by Hopkins was a disappointment because the cap that doubles as a dust cover and latch to the adapter has come off and missing after a few months. This cap is not replaceable, the whole connector would have to be replaced.

2007 Chevrolet Silverado
My 2007 Classic Silverado Crew Cab 4x4 did not have a factory hitch receiver, so I selected the 13322 Curt Hitch Receiver because it closely resembles the OEM hitch receiver and attaches to the bottom of the bumper. Installation was easy, as shown in the videos and described by other reviewers. All holes aligned perfectly. I did not remove the spare tire as it is not necessary. I used two jack stands to raise/support the receiver frame in place while I started the first bolts. I had the 22mm and 19mm sockets needed to tighten and torque the bolts/nuts. It looks great and I now am able to tow. For the wiring I installed the 30955 Hopkins 7-Way and 4-Way Trailer Connectors to the bumper adjacent to the license plate. This required drilling a 2-1/8" hole in the bumper, which was time consuming, but it now resembles a factory installation. I was able to remove the license plate and connect to the factory plug. I ordered these parts from etrailer for a number of reasons: 1) The website is intuitive and contains a tremendous amount of information for the person who is trying to research product information; 2) the selection and inventory is amazing; 3) the prices are very competitive – free shipping for orders over $99; and 4) the dedicated customer service is outstanding – the email communication is prompt. I ordered on a weekend and it was delivered by the following Friday. A very positive first experience.

Spent a little time on phone with Preston discussing a wiring solution to accompany the trailer hitch desired. He recommended a product and confirmed that it should be a plug and play situation. Long story short, the hitch was bolted up and the wiring functional in 1 hr's time. I had to drill (2) holes to mount the wiring receptacle, but that was expected. Great service, fast delivery, and excellent prices. I'm very happy. Vehicle: 2005 Chev 1500, 4-dr, 6-1/2 ft bed. Note: Factory wiring harness trailer plug-in was located above the spare tire, towards the rear of the vehicle.

Still works great - no issues at all.

Pretty easy to install. I originally ordered a more expensive version that was out of stock. This item is basically the same but a little cheaper. The one I originally ordered was to be connected to the truck bumper with self threading bolts. This one has little nuts and screws that are almost impossible to connect to the enclosed bumper. So I substituted my own self threading bolts. My other concern is the bracket could be a little stiffer. I'm not sure what the more expensive version is like, but this one could use a little more structure on the bracket. Time will tell how it will hold up. I may need some triangulated bracing on the sides to stiffen it up. Otherwise it appears to be what I wanted. I've yet to connect it to my trailers to see how it performs.

Worked fine for the few months I had the truck

Unit worked well as advertised. Old connecter had to stay (was welded) so I mounted off center a foot away. Now it protrudes 2 inches.
Comments
I use it infrequently. When I do use it, it works well. It would not mount as per instruction because of the factory offered trail hitch assy. Looks catiwhompus but does the job.

There may be a round plug with a cap inside your driver's side frame rail and if there is you can plug Hopkins 7-way plug # 30955 into the port for the 7-way.

If your trailer only has the basic light functions then you will only need to cut off the 4-Way and attach the wires according to the diagram I have included. Please note that when you attach the existing wires to the connector you cannot just go by wire color. You will need to go by function in...

Basically the circuit is only active under very specific circumstances which is why you aren't able to use your powered a-frame jack that draws power from the 7-way.

This will give you a 4-way connector as well as a 7-way connector at the rear of your Sierra. I have attached a link to an installation video you...
view full answer... - Adding a New 7-Way Trailer Connector to a 1992 Ford F-250 that Previously Had a 7-WayWhat you will need to do is test the plugs you have found with a circuit tester like # 40376 if needed. You will be testing for the various lighting functions, brake controller output (if still installed) and a good ground. If all the signals are there and working properly, you can hardwire in a 7-Way trailer connector. I recommend a multi-tow, like # HM48470, so you will have a 4-Way, 5-Way, and a 7-Way. What you will do is remove the plug on the end that works, clip it off, and attach...

view full answer... - Trailer Lights Do Not Work When Connected to 7-Way Connector on 2013 Ford F-350If you are using the part you referenced, Hopkins OEM Style 7-Way and 4-Way Trailer Connectors for Ford # 30955, and the 4-way works but the 7-way does not, the first thing to check is that the round connector that plugs into the back of the 7-way is fully seated and that the locking tabs are engaged. Since the 4-pole has lighting signals we know the vehicle wiring is sending the appropriate signal to the round U.S. car connector that plugs in to the OEM harness. This makes the plug-in...

- Troubleshooting Stop Turn Circuit of 2014 GMC Yukon XL Trailer Wiring Not FunctioningFirst thing I'd check is for a blown fuse under you hood. That's the most common issue that kills a trailer wiring circuit and is very easy to fix. Next possibility is corrosion on the pins of the trailer wiring. To fix that take some sandpaper to all of the pins on your 7-way. If the 7-way is looking pretty rough it might be best to replace it with a new one like the # A10-7072VP and you'd have an all new connector. Aside from that you'd have to trace wires to see where the issue might...
