Video Transcript for Hopkins 4 Pole Loop Review

Today we're going to be taking a look at the Hopkins 4-Pole Loop 12-inch long 4 Flat Connector, part number HM48145. Here you can see our loop installed. This is going to be ideal if you want to create a quick-connect situation for anything on your vehicle where you have to separate it at times by simply unplugging it and plugging it back in when you're ready to go back on. You can also use this as an extension harness for a 4-Pole Flat if you should desire if your plug is just a little bit too short. It's all in a weather-tight seal, rubber housing. It's going to help keep out corrosion and moisture. This will work for up to a 4-wire system.

If you only need to use 3 as we did in this case, you can just leave the other one blank, should you ever need it in the future. Now let's go ahead and show you how to install it. We'll take it and we'll just cut it in half. Then we can separate out our wires. We're only going to be using 3 of the wires on it so we'll go ahead and cut these wires flat at the end. I'm going to strip back about 3/4 of an inch or so, so we can twist these and fold them over since they are a thinner wire.

I'm going to shorten these back a little bit more. We don't need so much length. We're going to strip back our white wire, about 1/4 of an inch on these. Then we'll do our brown. Then well just use the yellow one that we're going to tie into our red.

The other 2 colors are going to match up to what we happen to be using on this vehicle. Now we'll be taking our red butt connector. It's an 18-22 gauge by Deka available at our website, part number 05730-5. We'll place them on our wire, grip it. We'll just give them a tug, make sure they're on there nice and tight. Then we're going to match up our colors.

This could differ depending on what you're mounting it to, your vehicle. I'm going to take some electrical tape, wrap up our harness, cover up our butt connectors to help keep moisture and corrosion and dirt out of the inside of our connectors. We'll push that down. We can go to the bottom side of our vehicle and finish our wiring. We're going to strip these back about 1/4 of an inch. We're only using 3 of them. We did not use the green on the other side so we won't be using it on this side. Install our butt connectors onto our wires. Now that we have all of those on there snugly, we're going to take our red wire that we stripped back about a half an inch. We'll fold this one over. We're going to put that to the yellow that we ran on the other side that was attached to our red wire. Then we'll crimp that. Then we're going to tie into our brown wire here. That's going to be for our tail lights. We're just going to cut this one here coming out of this harness and strip it back. We'll take those 2 pieces of the brown wire that we stripped back, twist them together. We'll insert that into the brown wire from our plug, crimp it, give it a tug. Then we just need to tie into our ground wire, which is going to be right here. We'll do the same thing. We'll twist those together, we'll crimp that to the white wire from our plug. Now we're ready to plug in our wire to our quick-connect. Just match it up, snap it together, and we'll tie up all of our wires and clean up our install. Now we're going to take some electrical tape before we zip-tie everything up. We'll just cover up all of our butt connectors to help seal out any moisture or dirt that can get into our wiring and help prevent corrosion. Then we'll take some zip ties. We'll tie everything up and we'll trim off our excess. That's going to do it for our look at the Hopkins 4-Pole Loop 12-inch long Connector, part number HM48145.

Misread the product description, thought it said 12’ instead of 12”. Will keep it for a backup. 637662

Have used etrailer in the past. Excellent service and products. Fast shipment. Will use in the future for everything trailers. 604315

by:

Not too much to say about it...it just works! Made it possible to connect to the wire receptacle in the bumper step. Simple, cheap solution. Printed identification on individual wires is a nice touch. Seems like it would be fairly easy for the wires to separate from each other. But, a little electrical tape should take care of that, if needed. The connections fit well. 398686

I would also like to thank George and Carol at etrailer for their outstanding customer service and communication from the time I placed my order through the time I received my order.

Cut it in half and used one end to splice onto a harness that I need an end on. 615865

Product was exactly what I needed. It was a few days later than originally planned but no problem. I ordered a hitch cap but when I received it the electrical connection was just a bit short. This fixed the problem. 609579

Product as described & solved my problem. Friendly efficient service. Fast track able shipping 607410

All items were received as described, packing was very protective and I ordered standard shipping but was upgraded free of charge. Great place for purchases for all your towing needs. 508864



- HM48145
by:

Excellent quality. 12" is good if you just want to extend your harness to relieve any stress /stretching when turning corners or if you want to replace an existing damaged plug (solder and shrink wrap your repair). 498935



- HM48145
by:

Would be nice if this came a bit more weather proof, but it's easy enough to add. 488101



- HM48145
by:

Works as advertised. The only improvement that is needed is my plug adapter was a five pin, so there is an empty space when using my four pin extension to my trailer. I had to tape over this to avoid corrosion on the adapter plug. Maybe a "fix" could be made in the future with a "dummy" 5th pin to plug into the adapter? 480425



- HM48145

It’s an extension with connections on both ends. What more is there to say. It works. 479530

I've got a 2015 Ram 1500 that I had ordered a lighted hitch cover for ... The harness on the cover was too short ... I used this for an extension and it worked great ... I received it two days earlier than expected ... Ordering was easy ... Thanks ... 474446

Very satisfied with the product. It was very well made and solved my problem of rewiring my auxiliary brake light that was trailer hitch mounted. 471956

by:

The Hopkins 12" 4-flat connector extension and the Hopkins mounting bracket are top quality and will allow me to extend my truck's factory trailer wiring connector to the mounting bracket for a professional looking install. The mounting bracket will allow a much easier disconnect of trailer from truck. The quick response from the etrailer Team is remarkable and I look forward to additional business with them. 462233

Just want to say that etrailer has the best customer service people! Melissa worked with me to get me the correct part after I had ordered the wrong part, and shipped it to me complimentary. Both the new part and the wrong part were high quality and will solve my wiring problem. Thanks to etrailer for working with customers to make sure they get what they need! 449923
