Video Transcript for 3M Accessories and Parts 804C Review

Today, we're going to review part number 804C. This is the 3M Scotch Lock quick splice wire connector. This is a blue connector and also has the gel on the inside. It is used for size 14 to 18 gauge wire. Basically, the gel that's used on the inside here is a weather protecting gel so when the wires make their connection, it helps resist corrosion. This is used to either connect two ends of wires together if you want to or I'll show you there is the other feature where you can connect it to a running wire where there is no end to it, you want to tap into that wire. You can use this connector also. Basically, also just wanted to mention to you it is stamped on here, if you look real close, it will say 3M and then AWG, which means American Wire Gauge and it will say 14-18, which means that's the gauge thickness of wire that will fit in here.

I got a couple of wires here I'm going to show you. Basically, if you want to connect them end to end, what you can do, the theory of this is you can see this metal piece in the . Once you push the wire in this side, it won't go any further and then what you'll do is if you want to connect two ends, this one will go in the other end and that one can go all the way through but what you want to do is if you want to connect end to end, you just put them like that. Once you push down on this top here and close it, there is a little ridge here that will lock into place. It will push that metal down and pierce both wires and give you a connection point. Then, you'll have two wires connected together. Now, the other thing you can do is if you wanted to connect, tap this green wire into let's say this white wire was running along a trailer, there's not end to it so you want to tap into it, what you can actually do ...

Let's take that off for now. You'll see this end where the lid is, pop it down and then what you can do is put your green wire in the same spot, run it all the way through, and see the gel come up. What that will allow you to do is slide onto a running wire just like that, push it back up, and it will snap into place. That way, it will allow you to tap into a running wire where there's no end to connect it to and do the same thing. Push down on this, squeeze it together with pliers to lock it into place and it will make a good, clean connection and then have the gel to protect it. You can use it either one of two ways when connecting wires. That should do it for the review on part number 804C.

This is the 3M Scotch Lock quick splice wire connector, blue in color, has the gel on the inside, and is designed for 14 to 18 gauge wire. .

This review is about service. Yes, the replacement tail lamp assembly and quick-splice connectors were shipped on time at a fair price. BEFORE they were ordered, however, my call was promptly answered and Sal M. walked me through ordering the proper components, and helped confirm I was indeed ordering the correct replacement part. He then went on and helped diagnose the problem with the left tail-lamp and confirmed I was ordering the correct part. He also provided valuable insight into the debug of a clearance light problem. This is the second time I've purchased from ETRAILER, and each time I do so I have received outstanding service from the phone team, products that work, and fair pricing with on-time delivery. 361886

These quick connectors make wiring up a trailer soooo much easier! I am definitely no expert on electrical stuff but the videos on definitely help and these connectors are pretty idiot proof! If you want everything to be smooth and aesthetically pleasing then use the heat shrink connectors but if you don't care what it looks like under your trailer because no one is ever going to see it, then use these!! 260106

The brake assemblies I received seem to be just fine. They were a good fit on my trailer. Haven't completed the job yet to try the brakes out, but they look great. All my other parts were correct and very well packaged. I really appreciate the great customer service. These guys seem to really care. 344528

Seemed to work just fine. The little blade may slip down in too far and prevent you from getting the wire pushed in all the way, at first. No big deal. Just pull the blade back a bit, and it'll work. The gel is a little thinner than I anticipated, but not a real problem. 132094

  • How to Wire the LED Trailer License-Plate Light # LPL55CB
  • You will need to use a quick splice, item # 804C, and splice the black wire from the LED Trailer License-Plate Light, item # LPL55CB, into the tail light wire on your trailer. The tail light wire is normally the brown wire, but you should use a circuit tester, item # 3808 if needed, to be sure you are splicing into the correct wire. You will then need to attach the white wire to ground, usually the trailer frame or the white wire coming from the trailer connector. Once wired the license...

  • Need to Tap into 7-Way on 2004 F-250 To Power Stop, Turn, Tail Lights on Headache Rack
  • Since you need to retain the use of the 7-way at your rear bumper for towing while having the same lighting signals available near the cab for your headache rack, one option to consider is using a 5th wheel harness such as # 41157 from Hopkins. This plug-in harness provides on one end dual round U.S. Car connectors in a Y-arrangement that allow you to tap into your existing 7-Way (while keeping all of its functions active for your tow rig). On the other end of the 8-foot cable is a standard...

Just kidding, there is a large group of people who don't end up using the reverse light circuit of their trailer wiring so I could see them not completing that circuit when they did your install. They should have asked you though. What you are going to need to do is first determine which wire of your vehicle taillight wiring carries voltage when the reverse lights are applied. To do this you will need to use a circuit tester like the part # 3808...

The brown wires will run to the running light circuit, the green to the right stop/turn, the yellow to left stop/turn and the white to the ground circuit of the trailer. This will give you all of the taillight signals on a 4-way that you would need for...

  • Recommendations for Splicing Running Light Wires on a Tear Drop Camping Trailer
  • Instead of using a quick splice connector, I recommend splicing into the wiring using a butt connector and then using some shrink tubing or liquid electrical tape, # SWC50122, to seal the connections from the elements. We have different size butt connectors like # 05732-2 for 12 to 10 gauge wires and # 05731-5 for 16 to 14 gauge wires. You will want to be careful when adding lights to a trailer. If you add too many lights, it could be too much power draw on the tow vehicle electrical...

The factory tail lights that come on the Keystone Outback 274RB do not appear to be LED and we do not carry an LED version of them, so your second set of tail lights may not match the original set.

For a junction box you can use # 38656. I have linked a couple of videos showing installations featuring these products for you. For a 7-Way trailer side connector you can use # H20046 with the wiring listed above. For the junction box you will also need some ring terminals. For the trailer...

To convert your wiring on your Dodge Ram 1500 to a 7-way, I would recommend the Brake Controller 7 & 4 Way Installation Kit, part # ETBC7 to convert your wiring to a 7-way connector and hook up to a brake controller.

You will connect the white wire to a good ground point and connect the brown wire wire to a 12V circuit.
