Video Transcript for Draw-Tite 5-Flat Trailer End Harness Installation

The 5 pole flat pincher 00:00:02 that we're using here to ease our installation for the trail wiring is part number 20017. All right, so we're going to convert our trailer with a 5 pole signal here, 5 flat. This is for Victor boat trailers because inaudible 00:00:15 the blue wire, here, which is the signal for reverse for your trailer brake lock out solenoid, so we'll strip off a quarter inch of the blue wire, here, and we'll install it into our buck connector here, that goes to our solenoid for hydraulic brake actuators. It is part number DM11993. We'll crimp it into place. We can hook up the rest of our wires to where they go, based upon our connection, here, and take our old connection, here, and cut off these zip ties to separate our wires so we can access them a little bit easier.

Now, we're going to start with what's our green wire, strip back to about 1/4". We're measuring off where we need to trim back our green wire. Get right about there. We'll cut the excess off of our green wire, strip back about 1/4", install our butt connectors. Now, we'll take the brown wire for our right side and we'll do that one, next. Then, we'll do the same for the other wires.

With all of our electrical connections made now, we can use our heat source, seal our heat shrink butt connectors up. To help tidy up our wires, I'm going to take some electrical tape, here, and wrap around our wires, just so we don't have a lot hanging down in this'll make a nice, clean install. Now that we've done that, we can actually go hook it up to our truck, and go down the lake and enjoy our boat. That completes the installation of the 5 pole flat pinch, part number 20017.

Decent 5 way plug. I did not use the blue wire taps, instead I soldered the connections as always solder wire splices that are exposed to the weather as my trailer stays outside. I did add corrugated wire wrap to it to make a cleaner installation. 200325

Ask the Experts about this Draw-Tite Wiring

  • What are the Wire Functions for the 5-Flat Trailer End Wiring Harness, # 20017
    The 5-Flat Trailer End Wiring Harness, # 20017, is what is a called a wishbone harness. The brown wires contain the running light signal. It is split at the plug and ran to each side of the trailer so you do not have to have a jumper wire between the two tail lights. So the wire that is yellow and brown goes to the driver side for running lights, and the green/brown wire goes to the passenger side for running lights. The all yellow wire contains left turn and brake lights. The all green...

  • Is Function of Blue Wire on 5-Way Connector, Part # 20017, For Reverse and How to Wire To 7-way
    The blue wire will connect to the reverse light circuit on the tow vehicle, but it will also send a signal to disengage the brake actuator on the trailer when you put your vehicle in reverse. So when you are in reverse, the trailer brakes will not be engaged. You would need a 7-way adapter like Adapter 7 Pole to 5 Pole Flat, part # A75TB. To wire the reverse lights on your trailer, you would need to connect the power wire from the trailer reverse lights, to the blue wire on the 5-way...

  • Is there a European 7-Way to US 4-Way Trailer Wiring Adapter for a BMW
    Bascially, there is no easy way to convert the European 7-Way to a US 4-Way. We do not carry any kind of adapter that you could use. You are left with 2 options. First, you would install a separate wiring harness which would be the easiest. Or, you could attempt to fabricate an adapter. You would need to use a converter, # RM-732. The red wire on the input side would attach to the brake light wire on the vehicle wiring. The white wire grounds to the frame. The yellow wire will attach...

  • Is There a 5-Flat to 4-Flat Adapter Available for a Ford F-150?
    It may be possible for you to use the 5 flat and 4 flat together, with all the functions still working except the one that is furthest from the ground wire. Should the connectors not be compatible, you could use the 5-Flat Trailer End 48" Harness # 20017. It is not a simple plug and play adapter, but it will work for you. I've added links to a couple of videos on this product for you to take a look at.

  • How to Wire Up an Adapter to Tow Trailer for Motorcycle that has a 5-Way
    Normally, the 5 wire flat connector will accept a 4 wire flat connector and work properly. The extra circuit on the 5 wire connector is normally wired to power a reverse lockout or electric trailer brakes not the brake lights. If your motorcycle has the brake light circuit connected to the extra circuit you will need to do some re wiring or install a converter, item # 119178KIT, on the motorcycle. Your trailer should be wired as follows. White wire = ground, brown = tail light, yellow...

  • Wiring a U.S.A. Boat Trailer to a 9 Wire European Trailer Plug
    The 5-Way connector on your boat will be wired as follows. Green is right turn/brake, yellow is left turn/brake, brown is running lights (both sides), white is the ground or earth connection and the blue wire is the reverse lockout or reverse lights. I searched for a connector on the internet that matches your 9 wire connector and came up with nothing. I would recommend using a circuit tester, item # 40376, and wire by function only. Have a helper activate all of the various functions...

  • Converting 4-Way of 2001 Toyota Tundra to 5-Way to Tow Boat Trailer with Surge Brakes
    We have a solution to convert your 4-way to a 5-way so that your reverse lockout solenoid can activate but we don't have a plug and play style of adapter. Instead your best option is a 4-way to 5-way adapter part # 20036 which plugs into your current 4-way and then gives you an additional wire you'd run to the reverse light circuit of your truck. You can use a quick splice connector part # SWC501746-1 to tap into the circuit easily.

  • Replacing Trailer 5-Way Connector with 6 Wires
    While the wire colors that are used on your trailer are a bit different, it appears that you simply have what is called a wishbone wiring harness. You can replace the 5-Way with a harness like the Draw-Tite Wishbone Style 5-Way # 20017. This style basically means that there is a separate running lights circuit wire that runs down each side of the trailer (instead of a traditional setup that would just run a single wire back and then use a jumper wire at the rear to go from one tail...

  • Can Euro 7-Pin be Replaced by American 4-Way?
    Sure, you can cut off the Euro 7-pin and add an American-style 4-way. I recommend using the Wishbone Wiring Harness # A20WB, which actually has five wires; it splits the running light wires so you do not have to run a jumper wire from tail light to tail light. You will need to do some splicing and you can use the accompanying diagram of a Euro 7-pin to see how they are typically wired. I recommend using butt connectors # DW05743-10 to connect the 20 gauge wires of the harness.

  • Wiring Options for a 2009 Chrysler Aspen Towing a Boat Trailer with a 5-Way Flat Trailer Connection
    Yes, the Tow Ready Custom Fit Vehicle Wiring for the 2009 Aspen by Chrysler, item # 118390, is the correct wiring harness for your Aspen and you will need one other item to complete the wiring to lockout the brakes on your boat trailer surge coupler. You can go one of three ways for this wiring. The easiest way in my mind is to install the # 118390 T-One and then splice the 5-Flat Vehicle End 72 inch Wiring Harness, item # 20016, to the 4 like wires left by removing the 4-way vehicle...

  • New 5-Way Trailer Side Connector for a Boat Trailer
    Your trailer has a type of wishbone harness with separate wires that share the running light circuit. For a replacement I recommend # A25W5B. The one covered pin is the ground, next to it is the running light pin. There are 2 wires associated with this pin. One goes to the trailer left side running lights the other goes to the trailer right side running lights. The next two pins are left turn/brake lights and right turn/brake lights. And the last pin and wire go to the electric reverse...

  • Towing a European Spec Trailer with a US Spec 2014 Ram Pickup Truck
    The issue that you are experiencing is due to the fact that the US and Europe use different types of connectors for trailers. In the US, the brake lights and turn signals are on the same circuit and there is just one circuit for running lights. In Europe, there are separate circuits for just about everything, which makes it easier to troubleshoot a problem should there ever be one. What you will need to do is change the connector on the truck to match what the trailer requires. To do...

  • T-Connector Trailer Wiring Harness for a 1998 Ford Windstar
    Many vehicles like your 1998 Ford Windstar have a 3 wire system with separate turn signals and brake lights. These vehicles require a converter which takes that separate signal and combines down to a 2-wire system used on most trailers. For your van you would use harness # C55346. It plugs in line with the vehicle tail light wiring. I have included a link to the installation instructions for you to view.

    Thank you for the photo; from that and your description it sounds like all you need is a replacement 5-Flat for your trailer and I recommend the 5-Flat Trailer End 48" Harness # 20017. What you can do is simply cut off the 5-flat that is on your boat trailer and use the quick splices that come with the # 20017 to splice into those wires.

  • Wiring 2005 VW to Tow Trailer with Amber Turn Signals Using 5-Way Connectors, Part # 20016 , 20017
    This is an unusual situation. Typically, trailers carry the brake and turn indicators on the same circuit, one for the passenger side, and one for the drivers side. The easiest way to wire this would be to cut off your existing 4- way connector and use a 5-way connector. Then wire the fifth lead on the vehicle side into the brake light circuit. You would need the 5-Flat Vehicle End, part # 20016, and the 5-Flat Trailer End, part # 20017. This would be the simplest way to wire your trailer.

    Traditionally you will find the running lights are brown, the left turn and stop is yellow, the right turn and stop is green, the white is ground, and the brake wire is blue. In your case it sounds since everything else is consistent that your electric brake wire is black. You can test these functions to confirm using a circuit tester like # PTW2993. Then you can use the Draw-Tite # 20017 your connection.

    The 5th wire on a 5-Way flat connector is intended to connect to the vehicle's reverse light circuit.

If you need a 5-Way flat trailer-side connector, you can use the Draw-Tite 5-Flat Trailer End 48 Inch Harness # 20017.

    You mentioned that the truck is a semi truck. Does it run off of a 24 volt system? If so then that would be why you are having bad luck with converters. Trailer LED lights run off of 12 volts just like incandescent lights but LEDs draw much less amperage so that is the big difference between the two types. LED lights can run off of a lower voltage but often times they appear dimmer. We have a converter # 119192 that is rated for 4.2 amps for brake lights and turn signals and 16...

    Replacing the connector on your trailer is probably the best way to go here. The connector you use will depend on what the extra circuit on the trailer does. If it is a boat trailer, and the extra pin operates the lock-out on a hydraulic brake coupler, using a 5-pole flat, part # 20017 along with a 7-way to 5-pole adapter like part # A75TB would be your best bet. If the extra circuit serves a different purpose, you would probably want to install a 7-way trailer connector, part # H20046...
