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. .

These quick connectors make wiring up a trailer soooo much easier! I am definitely no expert on electrical stuff but the videos on etrailer.com 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

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

Do you have a question about this Accessories and Part?


  • 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...

  • New Trailer Wiring, Connector, Junction Box, and Battery Box for a Trailer
  • We have 7-wire strands but no 5-wire. What I recommend is to use duplex wire # 10-2-1, sold by the foot, for the brakes and bonded 4-wire, # 16-4B-1, also sold by the foot, for the lighting functions. 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...

  • 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...

  • How to Complete the Reverse Light Circuit of a 7-Way Trailer Connector
  • Sounds like something Uhaul would do. 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...

You would need to use quick splices like part # 804C to connect the wires of this harness to the correct wires of your travel trailer taillight wiring. 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...

  • 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...

  • How to Add Reverse Lights to a Trailer That has a 4-Way Connector
  • What you will need to do is upgrade your 4-way to a 5-way. The fifth circuit will carry the reverse light circuit to the reverse lights you install on your trailer. On the trailer you will want to cut off your 4-way and install the part # A25W5B in it's place. The fifth circuit will run to the trailer lights to power them. On your vehicle you will want to install the # 20016. You will remove your current 4-way and wire this on it's place. The fifth blue circuit will run to the reverse...

  • What Do I Need To Equip My 2003 Dodge Ram 1500 Truck With to Pull Trailer That Has Brakes
  • Yes, when hooking your 2003 Dodge Ram 1500 with 4 prong wiring, to a trailer that has brakes, you will need to convert the wiring on your vehicle to a 7-way connector and install a brake controller. 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. Part # ETBC7 also has a 4 pole outlet, so you can hook up to trailers using...

  • Replacing 5-Pole Trailer Connector with Unusual Number Of Wires on Boat Trailer
  • Are you speaking of a 5-pole flat connector like part # 20017? Your description of the plug itself seems to match, but the number of wires on each pin sounds pretty unusual. I've provided a diagram of the usual wire functions on a 5-pole. As you can see, there's nothing unusual about the right turn, left turn and the two wires for the running lights on the driver's and passenger side of the trailer. Having more than one ground wire or more than one wire for the brake solenoid is...

  • Recommend a Small 24 Volt LED Light to Use On Electric Scooter
  • A red, 24 volt, LED, panel mounted light that I would recommend is the Optronics 7 Inch Round LED Transit Light, part # STL90R24B. You will be able to mount part # STL90R24B to the rear of your electric wheelchair scooter, but it will need to be wired up. To wire the light to your electric scooter, you would need to run the ground wire to the frame of your scooter or to a nut or bolt. Then, run the power wire into the wiring of the output that you connected the small beeper to. You...

  • Wiring Needed to Connect Royal Star Motorcycle to Trailer with Separate Brake & Turn Lights
  • Since motorcycles have separate stop, turn and tail lights just like your trailer you will not need any type of wiring converter to connect them, just the mating connectors of the appropriate format. If your trailer uses a 5-round-pin connector like # PK11501 that mates with the vehicle side socket # PK11502 that you referenced, then you'll just need to wire the socket on the bike. Please take a look at the linked article on trailer wiring that shows the various types of connectors. You'll...

  • We have everything that you will need to make something work, but we do not have a kit that was designed for this specific purpose. 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. If I were doing this on my trailer, I would want to choose lights that match the existing tail lights as much as possible. Something like the Optronics Low Profile...

  • Adding 4-Way To Rear of Trailer for Towing Second Trailer
  • To add a 4-way to the rear of your trailer will require you to hardwire a 4-way to the taillight circuits of the trailer. For that you would want the part # A35W42B which is a 42 inch long harness that would allow you to tap into the wires of your trailer circuits with quick splices like the # 804C. It might be easiest to run all of the circuits from your first trailer to a junction box like part # 38656 and then run the additional 4-way from that to your second trailer. I attached an...

If you have a 7-way already you will want to check behind that connection for a light blue wire. If you don't have a 7-way prewired you will want to look for a wiring harness up above the spare tire.

  • We have not heard of any backup cameras causing problems with light monitoring systems, but with new models that can change. In order to wire this camera to the car without use of the 4-Way, you will need to hard wire it. There are no connectors available for doing this. You will connect the white wire to a good ground point and connect the brown wire wire to a 12V circuit.

  • Best Method for Attaching Tail Lights to Aftermarket Flat Bed on 2008 Nissan Titan
  • I do not have a source for a plug that would mate with the factory harness for your OEM tail lights. Your best bet will be to use a circuit tester like part # 3808 and test the wires in the rear harness to determine their function. The black wire on the replacement tail light will attach to the running light circuit, and the red wire attaches to the turn signal/brake light circuit. Using quick splices like part # 804C would be the simplest method of making your connections. If you go this...

This is the only sure way to know which wire carries which lighting function. You'll need a helper in the truck to activate each lighting function while you apply the tester to the wires.

You will need to use a circuit tester like part # 3808 to test all of the wires running to the taillights of your vehicle until you find the one that carries 12 volts when the vehicle is in reverse. There should only be two wires run to the reverse light socket so it should be easy to determine which one to use. You...

Then you would just need to use a quick splice connector such as # 804C to tap in the backup camera wire to the...

I recommend installing a switch to turn the light on and off when needed, unless the light comes with a switch. Another option would be to run the wire from the cap light directly to the vehicle battery. Again, I recommend installing a switch if you do not already have one so the light does not stay on all...
