Video Transcript for Tow Ready Replacement 7-Way Harness Review

Hi there, towing enthusiasts. Today we're going to be taking a look at Tow Ready's replacement seven-pole pigtail harness. This replacement harness will work with any seven-way connector that uses a standard round plug at the back. So if you have a damaged harness on your vehicle, you can simply buy this, cut out your old wiring and splice in your new harness. What else I like about this harness is that it comes with heat shrink butt connectors for all of our connections, and they provided the appropriate sizes, as some of your wires on your seven-pole use larger diameter wires. So we've got our yellow butt connector here for the heavier gauge wiring and blue butt connectors for our lighter gauge wiring.

By utilizing heat shrink butt connectors, instead of your standard butt connector, our replacement harness is going to have a significantly longer life, because we're going to be keeping all the moisture out from inside of our connections when we splice them together, which is going to result in corrosion not occurring. Whereas if you use standard butt connectors, moisture can easily get down in there and cause your connections to deteriorate quite rapidly.We're replacing the factory harness on our motor home here because we have damaged wiring and missing pins in our connector. We would need a fully operational seven way on this. So we're just going to cut out this old one, getting rid of these wires here on this side, where we had one that was already damaged. We've already cut it here.

And we're going to put our new one in. Now one of the things you're going to notice is the color wires. Now this does have all the same color wires on our factory connector here, but they are in different locations and that's not uncommon on your motor homes and some of your vehicles to have wire color coatings not in the standard position. So since they do have the same colors, but they're in different positions, we can't just simply take these wires, cut them and then match our colors back up because then our pins are going to be in the wrong location.So what I'd recommend you do rather than trying to match colors on any vehicle is to just do them one wire at a time. So that way you can verify you're putting the correct wire in the correct location.

So if we hold them up here side by side, we can see them here. I've already cut this wire, which was a blue wire on our factory connector. And that does match up with the blue wire here on our new connector. But if we go to the left one pin, we've got a brown wire on our new connector and it's a green wire on our factory connector. So we already know that when I cut this green wire here, I'm going to have to splice it to the brown wire on this connector for it to be in the exact same pin location and give us the same operation that we had before.So since our blue wire was already damaged, I've already got it cut here.

We're going to start with that one. We already verified that the blue wire here did match up with the blue on our connector. So we're going to strip back on the other side here, because this is where we're going to be connecting our new connector to. We'll now take our new harness. We've got the blue wire here. We've pre-crimped on butt connectors on all of those wires. Now I'm going to connect to the other end of the butt connector for the blue wire to the blue wire that we had cut here. Once we get this wire crimped, we're then just going to repeat this process that we did before of holding our connectors up to one another, looking at the wire colors side by side at the back, making sure you've got them the same, because I do want to point this out too.There's a little tab there that you think that's maybe the release tab. This is the release tab here. So don't get these confused and hold them up with the release tab and this other little tab there. You want to make sure you've got the same tabs when you're doing this as well.So we're just going to move on one at a time, cutting and crimping on our new wires now. Now that we've got all of our wires connected, all we need to do is heat shrink down our butt connectors. So we're going to grab a heat gun and then just heat all those up and they'll shrink down. Once you've got all of your wires heat shrink down, then simply plug your round connector into the back of your seven-pole.And that completes our look at Tow Ready's Replacement Pigtail Harness for your seven-way connector.

Average Customer Rating:  4.8 out of 5 stars   (44 Customer Reviews)

Well I fixed my brake control problem on my Ford F-250 Super Duty. I learned how to bench test my Tekonsha 9030 Voyager brake control from your website and ruled it out, then I focused on the wiring harness at the hitch. The 7 way plug worked in the bed at the fifth wheel, but not at the hitch. I checked for continuity at the wire harness connector and the 7 way plug and discovered that the connector end of the harness was bad. I ordered the splice in style Tow Ready Replacement 7-Way Harness and Socket for Factory Tow Package and that solved the issue. I found that the corresponding wires on the replacement were not all the colors as the corresponding OEM wires, so I matched them up by position without further issue. I pleased with the outcome and price I paid for the product. 702940

When all the auto stores said it was a junk yard only item because not even the dealership would sell the pigtail, etrailer.com proved them wrong. My pigtail was corroded and I didn't want to spend hours trying to find another one at the junk yard. It looks and feel just like factory minus where I had to join them together. 938282

After being told by the Ford dealer ship that I could not buy just the oem pig tail wiring harness which someone kindly cut from under my truck I was upset because the wiring harness was very expensive to buy and replace Finding this product and the ease of wiring it in to my truck for pennies compared to buying the whole harness was great. The only down side was using the usps for shipping and it took several days longer to get the order. 936125

  • Does Hopkins 7-Way Harness # 20147 Fit Standard 7-Way Connectors
    I can't find any info on a Hopkins or other brand 7-way with a part number of 97149 but if you have an OEM style 7-way connector on your vehicle the # 20147 has the correct round connector. This also is the correct connector to plug into a combo 7 and 4-way like part # HM40975 which I believe you may interested in as well.

  • Does 7-Way Round Connector # 20147 Fit 2018 Chevy Silverado 1500
    The round connector of the # 20147 is the exact same connector as what's on your 2018 Chevy Silverado so once wired to your truck it would be exactly the same. The blue wire of this would carry the OEM brake controller voltage to the trailer brakes like needed as well. For a new 7-way connector in case yours is broken or damaged you could use the # HM40975 as well which will plug right into this round connector.

If this connection works correctly then you will want to replace the 7-way connector on your vehicle because it has an internal issue. If this is the case, I recommend the Hopkins...

  • How to Remove 7-Way Trailer Wiring Plug from Socket on 2015 Audi Q7 with Factory 7-Way
    A vehicle 7-way harness will have a locking tab of some type to ensure the wiring harness remains connected to the socket. This is an important safety feature for maintaining all of the trailer signals but especially so for the power to the trailer brakes. The exact appearance and operation of these locking tabs can vary. For example, on Hopkins 7-way harness # HM40975-11998 there is a small grey locking tab, shown in one of the linked photos, that slides to lock/unlock the connection....

  • Troubleshooting RV Backup Lights Staying on When Towed Car is Connected
    The most likely cause for the RV backup lights to suddenly stay on when your towed vehicle is connected is corrosion in the RV connector. In a 7-way socket (please see photo) the 12V power contact at the 1:00 position and the backup light contact in the center can become bridged together. This can occur from corrosion on the inside of the connector or from trapped water or other foreign material that connects these two circuits. You can try an aerosol electrical contact cleaner like...

It would be best to inspect the connectors for any damage as well. As far as fuses go, if you turn to page 162 in your copy of the owner's manual you should see that the fuses in locations 6, 38, 101, 115, and 305 are for the various trailer functions.
