Today on this 2005 Nissan Armada, were going to install part number 30955 from Hopkins. Now our Nissan here has part of a factory tow package. It has wires around at the back, but does not have the actual connector, so were going to use this part to finish up the connection, so we can plug in a trailer. All right, first off well go ahead and pull out the wire harness from the vehicle. Now normally this would have a cap, however on this particular vehicle it did not have the cap. Now well take our connector and plug it into it. Well also use some dielectric grease to help protect the leads as well.
Now we need to attach it to our hitch. Now our bracket that we are going to use to attach it to the hitch is going to be part number 18140 and well use that with the mounting bracket that comes with the trailer connector. Now well do a test fit and you can see that, the bracket is going to be a little bit on the short side, so what were going to do is take our bracket down and using our 7-pole bracket, were going to use it to mark and drill a couple of holes towards the end just to give us enough clearance. So were going to hold the two together and push it towards the edge and then well use a yellow marker to mark our holes. Then well take our bracket and put it in a bench vise and drill out the holes up to a quarter inch.
With our holes drilled out, well go ahead and inaudible 00:01:14 two pieces together. Using the hardware that comes with part number 18140, well go ahead and connect the two together and well use a clamp to attach it to the hitch. Then well go ahead and take our 7-pole connector and attach it to the 7-pole bracket. Well bolt those two together and you can see how the bottom edge of the connector touches the hitch a little bit, so actually take the bracket and pull it away a little bit just to take the tension off and well make any minor adjustments to the bracket going to the hitch to keep it level. Were done with the back and we need to go underneath the hood of the vehicle to install two relays.
Well take off the cover for the relays and there are two spots that are open. Theyll be labeled trailer tow number one and trailer two number two. Now were going to using the relays from part number C57000 from Curt. Well be using the brown relay and one of the blue relays. Well have a third one that will not be used.
Well go ahead and put those into place. Now the reason why we checked to install these relays is, when we tested the wire harness, we found out that we have left turn and right turn and brake signals, but nothing else. We checked the relay box and we found the two relays missing, so thats why we added them. With that, thatll finish if for our install of part number 30955 from Hopkins on our 2005 Nissan Armada. .
Was what I ordered and installed great
Quick easy install !!! Great product !!!!
WORK GOOD, FIT RIGHT UP, THANKS. IT DIDN`T TAKE CARE OF THE PROMBLE.
Just the right part replacement I needed. Very fast email shipping notice and good delivery time.
Great product, timely shipping and I was followed up with via email after the product was delivered. Couldn't have chosen a better place to purchase from!
Plug did not snap into vehicle outlet as tight as I would like, but overall works fine.
Excellent, direct OEM replacement for my 2001 Chevy Silverado, at a very reasonable price. Product arrived at my home within 3 business days of ordering. Nice job E-trailer !!!!
Perfect fit and excellentThe wiring harness was exactly the part I was looking for. It was well built and very easy to install.
Connection was spot on and seems decent quality. Very easy install. Only two things I wish were better would be if the wires came wrapped and the bracket was a slightly heavier gauge steele.
Plug and play was what I needed
Great fit works good has 7way rv plug and the regular flat 4 plug no need for adapters to lose or have stolen.
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.
Product is ok, I was hoping for something a little more durable, seems cheap. I guess we will find out
I received it and I just got done installing it. Looks great and appreciate you and your team for a pleasant experience all around , thanks again !
no issues with the install, connector on the part matched the plug for my o.e.m. trailer wiring harness, all trailer light worked as they should.
Works great!!! Thanks....

Still working great. Thanks for a great product...
Awesome product easy installation
The plug bracket needs adjusting to fit on the 2015 Q7 TDI
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.
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.
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..
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.
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 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.
