Video Transcript for Trailer Wiring Harness Installation - 2014 Ford Van

Today on a 2014 Ford E350 van we're going to review and install the Draw-Tite 4-pole 72-inch Long Vehicle End wire harness, part number 18172. This is what a wire harness looks like when it's installed in a typical application: simple 4-pole flap right here that will work with any small trailer that's out there. This also provides a great base if you want to upgrade this from a 4-pole off to a 6 or 7-pole connector when you use a bigger trailer that requires extra circuits. Let's go ahead and take a quick look at it. Very simple. This is an industry standard 4-pole flap. This is our wires here, 18 gauge material.

This is plenty enough for all your lighting requirements on virtually any trailer that's out there. Let's look over the code real quick. White wire is going to be your ground, brown wire is going to be a running light circuit, yellow is going to be left turn and stop light, and green is going to be your right turn and stop light. Of course the length of this, like we said before in the title, is going to be 72 inches long. There's a few options for your van to install the wire harness but it maybe worth to look at underneath the van and look for remnants of a tow package underneath there. We took a look at this one, we'll going ahead and show you what we can hook up to.

If yours doesn't have that you probably have to go with more expense options, but we found this and we'll go ahead and show you how to do it if you have the same thing on your van. Now to find the end of the wiring harness, we need to go to the left side or driver's side frame rail. We'll follow it all the way back until just between the cross number 00:01:30 here. If you look behind this cross number here, we can see our connection point. This is the connection we want to look for. I have it already disconnected.

It just unsnaps from a bracket on top here, and here's our wires. Lucky for us, it's going to be a color for color match up. Let's go ahead and remove some sheath here, a little bit better access to our wire harness. All right. Yeah, we can cut at the end here, but I'm actually going to cut up just a little bit further up just in case we ever need to reattach this back to our wire harness for future upgrade for a factory tow package that would plug in here. All right. At this point, all we need to do is strip back the wires.

We'll twist them together, and we're going to add some inaudible 00:02:22 felt connectors. I'm using these guys because this sits in an outside environment. This will seal it for connections once we're done. Butt 00:02:30 connectors do not come with the wire harness that we're using. We added this on. This is part number DW05744-5. We'll go ahead and strip our wires back. By the way, I also have to twist the wires so that gives more solid surface for the crimp connector to work with. All right. This will be a color for color match up . makes it nice and easy. All right. Let's go ahead and apply heat to them. We're going to use a heat gun, which is the proper way to do it. Yeah you can use a cigarette lighter, but chances are that you'll get to close to it and it actually gets too hot, so you end up damaging your connector and over time it will crystallize and break. You will be back in the same place where you we're before. We'll use some of our left over lube 00:03:36 material to help hide our connection points, and then we'll take a wire harness and we'll run it back towards our hitch. Pretty easy. We're just going to route it through the openings at the end of the cross numbers. And then we can go ahead and run it out to our hitch. We'll go ahead and take a few moments and we'll go ahead and zip-tie our wire harness up to make it safe and secure. Leave out enough length that you want and then we'll go ahead and zip-tie the rest to an existing hole in the bumper. We'll bundle up our excess using a few more zip-ties. Zip-ties do not come with the wire harness either. Any time we do electrical it's always a good idea to grab yourself some zip-ties. Once your satisfied with the way you have it, we'll go ahead and cut off the ends of our zip-ties. All right. Let's go ahead and try out our work. Now I'm using a tester to check our wires before we try it on our trailer. I'm using part number I26. First turn on the running light circuit. We should see the running light wire, the brown wire come on. Our left turn signal, which will be a yellow wire. Then our right turn signal, which will be our green wire. Then we should like for a solid signal on the yellow and green wires when we hit the breaks. Okay, with that looks like everything's working. And that will finish it for a 4-pole 72 inch Long Vehicle End, part number 18172 from Draw-Tite on this 2014 Ford E350 van. .

  • How To Determine if a 2006 Jeep Grand Cherokee has a 7-Way
  • If you look at the back of your 2006 Jeep Grand Cherokee and see a wiring connector that looks like the Tow Ready Wiring harness part # 20135 then you have a 7-way. Another option you could have is a 4-way which would look like part # 18172, or you might not have any connector at all. To add a 4-way you would first want the Tow Ready Wiring harness part # 118394. If you needed to upgrade to a 7-way you would need the 4-Way to 7-Way adapter part # 37185 after installing the #118394. For...

  • How to Install a 7-Way Trailer Connector on a 1999 Freightliner FL-Series
  • In order to add a 7-way trailer connector to your 1999 Freightliner FL-Series you are going to need to first hardwire a 4-way trailer connector like part # 18172 and then a 4 to 7-way trailer connector like part # 37185. In order to power the 7-way trailer connector you are going to need to use part # 12-1-1 (per foot) and part # PK54530. A circuit tester like part # ALL640595 will also come in handy if you do not already have one. If the trailer has brakes then using part # 18172 for...

  • Adapting 5 Pin Round Connector on Harley-Davidson to 4-Pole Flat Trailer Connector
  • The extra wire on your 5 pin H/D plug will serve one of two purposes. It is either the brake light signal or a constant 12-volt power feed to the trailer. You can easily determine which case you are dealing with by using a circuit tester like part # 40376 on the plug. Activate the turn signals, running lights and brakes to determine which pin carries which circuit. If the extra pin carries a constant 12-volts, and your trailer does not require any power supply, you could simply construct...

  • Brake Controller Installation for 1991 Ford E-350 Van Towing an 18 Foot Trailer
  • A brake controller is definitely a good idea and is the only way to activate electric trailer brakes. For your 1991 Ford E-350 I recommend the Tekonsha P2, # 90885. This is a high rated and economically priced brake controller that gets good reviews. For wiring I have included a wiring from scratch FAQ below. I also included a video showing brake controller installation on a similar vehicle. You basically need three things to wire a brake controller. First is the brake controller...

  • Adapting 5 Pin Round Connector on a Trike to 4-Pole Flat Trailer Connector
  • I have some options for you, however, I am not familiar with an adapter to convert a 5 pin round trailer connector to a 4-pole flat trailer connector. Since your trike has a 5 pin trailer connector, the extra wire on your 5 pin connector will serve one of two purposes. It is either the brake light signal or a constant 12-volt power feed to the trailer. You can easily determine which case you are dealing with by using a circuit tester like part # 40376 on the plug.

  • Parts Needed to Connect a 5-Pole, Round Connector to a 4-Way Flat Connection
  • You could put together an adapter using part # PK11501 and part # 18172 for the 5 pin round/4-Way Flat connection that you need. For the 2 female - 5 pin round connectors, you'll need part # PK11502 This 5-pole socket will connect your trailer to tow vehicle. The female/male terminology can be a bit confusing because of the pins in this connector. Part # PK11502 is actually an industry standard female connector because part # PK11501 plugs into it. I have also attached a link...

  • Converting Separate Turn Signals and Brake Lights on a Motor Home to Combined to Use a Light Kit
  • I will be happy to help you out. The separate brake light circuit is going to have to be combined with the turn signals in order to use a light kit with a 4-Pole connector. There is a special converter for this, # RM-732. On the input side you will connect the right turn signal wire to the green lead, the left turn signal wire to the yellow lead, and the brake light wire to the red lead. The converter will properly combine the signals and on the output side you will have green for right...

  • Trailer Wiring Recommendation for a 1992 Chevy C/K Series 1500 Pickup Truck
  • It sounds like you have wiring that is connected to a third brake light like on a camper shell. What you will need to add a 4-Way flat trailer wiring connector to your 1992 Chevy C/K 1500 is the Tow Ready Custom Fit Vehicle Wiring, # 118315. This harness just plugs in line with the tail light wiring on the truck, on the driver side rear frame rail near the bumper. I have included a link to the installation details for you.

  • Trailer Hitch Receiver Recommendation for 1970 Chevrolet Chevelle
  • Although we do not have a custom fit hitch available for your 1970 Chevrolet Chevelle, I have a hitch that should work for you. Take a look at the Curt Adjustable Trailer Hitch Receiver, # C13701. This is a universal style hitch receiver that will fit frame widths of 18 inches to 51 inches and can be bolted or welded to the frame. Since the frame of a Chevelle is not 51 inches wide, you will need to make sure that you have enough clearance past the frame for the longer cross tube or...

  • Adapter for a 6-Way Round on a Harley Davidson Trike to a 4-Way Flat Trailer
  • It does not appear that any of the 6-Way to 4-Way adapters are going to work because of the unique pin out that is on the 6-Way on your 2013 Harley trike. You would essentially need to make an adapter to match the pin out. You will need a trailer side 6-Way, # PK11604, and a vehicle side 4-Way, # 18172, cut to the length you need. Then you just attach the wires in the right place to match the 6-Way you have. On the 4-Way end the white wire is ground, yellow is left turn and stop, green...

  • You will need to hard wire the trailer brake controller on your 8000 series Ford. The following items will be needed for installation. Brake Controller, I recommend the Prodigy P2 Brake Controller- Proportional, item # 90885, which is very easy to use and adjust with differing loads.

  • Hooking up Trailer Lights for Double Trailer Towing
  • It sounds like you want to tow a pair of trailers in line, and to hook up the lighting you will need to use junction box # 38656 along with 4-flat connector # 18172, which you can mount with brackets # 18144 and # 18140. You are going to run the lights from your camper to the junction box and then to the 4-flat connector. You may need extra wire # DW02923-1 and butt connectors # 05730-5 as well. I've added links to video reviews of these products to take a look at as well.

  • The E-Z Mount Tow Light Kit, # EZT20B, provides stop, turn and taillight functions for flat towing. If you need an extension There are several options depending on the length that you need.

  • Trailer Wiring Harness Recommendation for a 2004 Pontiac Montana
  • Actually, all you will need to do is install a wiring harness, # 118355, on your 2004 Pontiac Montana. But if you wanted to use those factory wires, because you have separate wires for turn signals and brake lights, you would first need to install a converter. The converter, # RM-732, takes the separate signals and combines them which is what a trailer uses. To wire it up your yellow wire will go to the yellow wire on the converter, green will go to green, white will go to white, and...

  • The European 13-Way trailer connector does basically the same thing as the US 7-Way does except that the European version has a separate circuit and pin for every function. here in the states the turn signals and brake lights are combined on each side and there is just one running light circuit. In order to adapt the 13-Way you would need to determine which wires control brake lights, turn signals, and running lights on the 13-Way. Then you would take the left turn signal wire and attach...
