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. .

Product exactly what I was looking for. Fit factory harness perfectly. Strong and rigid, appropriate mounting hardware. Perfect




by:

Great fit works good has 7way rv plug and the regular flat 4 plug no need for adapters to lose or have stolen.


Comments
Been using this plug for a year now still working great
jason l - 09/19/2020


by:

This muti-tow plug with the wire extension plugged right to the factory truck harness with enough length to mount under the service body's bumper. The local stores plugs would not work for this service truck.




by:
2004 Chevrolet Silverado

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.




by:

I was having problems with my trailer breaks and lights. Finally figured out it was this pigtail. This one works awesome.




by:

Easy to install and plug and play with factory harness. Should come with wire loom like the factory to protect the exposed wires. Luckily I had a piece to use.




by:

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.




by:

This connector interfaces with truck wiring harness. It makes wiring to tow a snap.




by:
2003 Chevrolet Silverado

Plugged into the existing wiring with no problems! Excellent product!




by:

Perfect replacement easily installed shipping was quick very happy




by:
2007 Chevrolet Silverado

Easy installation on my 2007 classic Silverado Chevrolet




by:

Cut a hole out on the rear plate of the Tommy Lift and screwed it on. Plugged right into the provided plug from GMC.




by:

Nice product ,Easy to install and then worked as supposed to . I installed in bumper as opposed to the add on bracket that came with it ,made for a easier way to plug in trailer cord.




by:

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!




by:

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.




by:
2006 Chevrolet Silverado

in my case I have to say that first look at YouTube from there I got the video with the description of the process and the number of the part of there just went to etrailer.com I put the # alone went out it was really easy to send fantastic just wait 4 days in regular shipment for the installed only you see that plug it in thank you I hope that some more will serve..




by:

It’s works as it should just wish the plastic at the area where the screws mount was a little more beefy.




by:

I Liked the easy connection that Help me A lot.




by:

The product was an exact one-for-one replacement. However, I ended up having to replace the female connector due to corrosion. This took a bit of time. The result was all new connections that work fine. Thanks for all your assistance.




by:

Worked great.




by:
2006 Chevrolet Silverado

I bought this 7 way trailer connector to replace a broken one on my 2006 Chevy 2500HD. It was an easy install and only took a few minutes to complete. I tested it with my trailer connected and all works fine.
The shipping was super fast.
Thanks , etrailer.




by:

drop in replacement with the factory ha rness.




by:

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.

2007 Chevrolet Silverado Classic

Worked perfectly. Looks good. No complaints.

Probably would have been done in 30 min, if I could have gotten the old one off in a timely manner.




by:
2007 GMC Sierra Classic

Hitch and wire harness fit great.
Delivery
was 2 days earlier than expected.
Great job etrailer.

  • Under Hood Connections Required to Activate Tow Package Wiring on a 2008 Chevy Suburban
    There are some connections that you will need to make under the hood of your 2008 Chevy Suburban to make the tow package wiring fully functional. We actually have an FAQ article that I have linked for you that explains what to do. You will need the section near the end called Finalizing Connections for the Brake Controller. In the tow package wire bundle from under the dash, you will make the following connections to the brake controller: Tow package Red connects to brake controller black...

  • Troubleshooting Trailer Passenger Side Stop Turn Circuit Not Functioning
    First thing I would do is ask your buddy what all he messed with, if you can get him to undo the damage he did to your trailer you will be in better shape. It sounds like the original problem you had was just a bad ground on the passenger stop/tail light. Typically light assemblies ground through their mounting hardware so ensuring this light is attached to a clean metal surface would be a great place to start and would most likely fix the problem. I attached a trailer wiring diagram for...

  • Does the Cover on 4- and 7-Way Trailer Connector 30955 Lock the Trailer Connector In Place
    What your are describing is a common feature of most every 7-Way trailer connector including # 30955. They are designed that way for the exact reason you explain: it locks the connector into place so it cannot accidentally pull out.

  • Location for Installing Hopkins # 30955 Replacement Multi-Tow 7-Way and 4-Way Trailer Connector
    You are entirely free to choose an alternate mounting location for your new 7-way as long as your factory wiring harness can still reach its location. Your vehicle and trailer will not care on which side of the hitch their electrical connection is made. I do suggest you first make certain that your trailer connector can reach your new preferred location on the vehicle when the trailer and vehicle are hitched. You also need to be sure the OEM harness on the vehicle (with the round U.S. Car...

  • Wiring Harness to a 2013 GMC Sierra Trailer Connector is Locked On
    I have included a link to a video that should help you. The wiring harness is connected to the trailer connector on your 2013 GMC Sierra with a white or gray lock. The easiest way to remove it is to use a very small flathead screwdriver and push/pry the lock out of position so you can then pull it out. Then there is likely to be a spot on the connector housing that you will need to push in while pulling out the harness at the same time.

  • Availability of Trailer 7-Way and 4-Way that Can Have Both Connectors Used at Same Time
    For a similar 4-way and 7-way to what you referenced that uses the same round connector to install to the vehicle we have the Hopkins harness part # 30955 which has a lid design that allows you to access both at the same time.

  • Troubleshooting Trailer that Illuminates Trailer and Vehicle Running Lights When Connected
    There must be a short on the wiring of the trailer you are towing or on the tow vehicle. Sounds like it has to do with the running lights and the 12 volt power circuit. Since it only happens when the trailer is connected I would expect it to be on the trailer side of the situation. Check out the 7-way wiring diagram I attached and compare that to how the 7-way of the trailer is wired. You would also need to look for obvious signs of a short like cut or exposed wiring or corrosion. If...

  • Brake Controller Installation on a 2007 Chevrolet Silverado
    If you have a 2007 Silverado with the Classic Body style, as long as the connector port is there underneath the dash and you have a factory 7-Way connector port at the rear, all the wiring is in place and you would be ready to use your brake controller. If your truck does not have a factory 7-Way, you would need part # 30955. It is a 7-Way harness that is plug and play. We have this part used in one of our installation videos so I will provide a link to that video as well.

  • No Power To Lights On Trailer
    If you are not getting power to any of the trailer lights then your issue is most likely with the trailer plug. The first thing you will want to do is remove the ground, sand down the surface, and attach with new hardware. If this does not fix your problem then you will want to make sure the wires are secured leading into the plug and that there is no corrosion inside the pins. If still no power then begin tracing the wires back to each light while checking for breaks. If no breaks are...

  • No Power To Factory 7-Way Plug After Loading Boat Into Water
    The first thing you want to do is unplug the factory 7-way plug from the factory tow package port. Take a circuit tester and check the circuits of the factory wiring port for power. If you have power on the circuits and not the 7-way plug then the plug needs to be replaced. You can also make sure the 7-way plug is fully seated with the factory wiring for a good connection. You also want to make sure the 7-way plug is properly grounded to a clean bare metal surface if it has a separate ground...
