Video Transcript for Draw-Tite Wiring - Trailer Connectors - 20017 Review

Today, we're going to be taking a look at part number 20017. This is the Draw-Tite 5-Flat Trailer End 48" Harness. It's going to provide your 5-flat electrical plug or connection point here, at one end. The thing about a 5-way flat system is that it's going to contain that fifth wire. That's going to be the blue wire. That's going to carry the reverse light signal from the vehicle to the hydraulic brake actuator on your trailer. It's going to lock out the actuator from working when going in reverse. The overall length of the harness is going to measure 48".

This will work or plug into most 4-pole flat connectors. Just keep in mind that when it's used with the 4-way flat, the reverse lockout feature will not work. It's going to include 4 wire taps for easy installation. That's just going to be an easier way to connect the wires to whatever system you're hooking it up to. The gauge, when it comes to these wires, are all going to be 16 gauge. The all yellow wire is going to contain the left turn and brake lights.

The all green wire is going to contain right turn and brake lights. The white wire is going to be your ground connection. That needs to be connected to a clean, bare metal surface on the trailer frame. Brown wires, you've got one that runs with the all yellow wire and one that runs with the all green wire. The brown wires are going to contain the running lights signals, and your blue wire can be used for a couple different functions, like if your trailer has a surge brake coupler with electric reverse lockout or reverse lights.

The blue wire would be ran to one of those. The 5-way connector here has some nice grips on the sides, so it's going to allow you to easily connect and disconnect as needed. That's going to do it for our review of part number 20017. This is the 5-Flat Trailer End 48" Harness from Draw-Tite Wiring. .

Purchased wiring adapters ,LED lights delivery shipment was very prompt and accurate GREAT SERVICE,,,,,picts of end product



by:

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.

Ask the Experts about this Draw-Tite Trailer Wiring



  • 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.

    The 5-Flat Trailer End 48 Harness, item # 20017, does have 6 wires. There are two for the running lights functions - one for each side. The wire harness has 16 gauge wire and comes with wire connectors for 16 gauge wire.

  • Replacement 5 Way Connector Needed for Yamaha Boat Trailer
    Sounds like Fido needs a first class ticket to the dog house! LOL For a 5-way replacement connector for your Yamaha boat trailer, Draw-Tite offers part # 20017 which includes the connector with 48 inch wiring lead and 4 quick splice wiring connectors. The standard wiring on a 5-way flat connector are : White wire - Ground Green wire - Right turn/Brake Yellow wire - Left turn/Brake Brown wire - Taillights Blue wire - Reverse light circuit Since you mention that you have 7 wires going...

  • Availibility of 5-Way Quick Fix Connector
    Unfortunately, we do not offer a 5 wire quick fix kit. I would recommend cutting off the broken connector on your trailer and using a 5-Way trailer end connector, part # 20017 to replace it.

  • How to Install The Draw-Tite 5-Flat Trailer End 48 Inch Harness # 20017 On A Trailer
    On the Draw-Tite 5-Flat Trailer End 48 Inch Harness, part # 20017, the wires are connected as follows, White wire is ground wire Green wire is right turn/brake Yellow wire is left turn/brake Brown with green tracer is right side tail lights Brown with yellow tracer is left side tail lights Blue wire is the reverse lockout or reverse lights Normally on a 5-flat connector it would just have an extra blue wire for the reverse lockout feature on boat trailers with a hydraulic coupler....

  • 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...

  • 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 this...

  • How to Wire Back Up Lights on a Trailer Equipped with Standard 4 Pole
    Using a circuit tester, find out if the center post of the 7 pole connector is wired for reverse lights. If it is, then you can convert your trailer to a 7 pole using the diagram on our Trailer Wiring FAQ page that I have provided a link for. If the 7 pole is not already wired, the simplest solution would be to switch your trailer to a 5 pole system. Re-wire your trailer using part # 20017, using the same colors as before, but the added blue wire will be run to the new reverse lights on...

  • 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.

  • Recommended 5-way Trailer Connector Harness To Connect to 5-way Flat Connector On Motorcycle
    I would be happy to help! To replace your current 4-way flat connector I recommend the 5-Flat Trailer End 48" Harness # 20017 which will plug into the 5-way flat connector on your motorcycle. The reason I recommend replacing is it will be a quick install, and the 5-way to 4-way adapters offered have the wrong ends for what you are looking to do. I included a video of the # 20017 for you to take a look at.

  • 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.

  • Do I Need a 5-Pole to 4-Pole Adaptor to Tow a Small Utility Trailer With My 2000 GMC Sierra
    Since you have a 5-Pole flat connector on your truck you should not have to make any modifications to plug the 4-Pole connector on the smaller trailer into the 5 pole connector on the truck. Basically a 5-Pole is set up exactly like a 4-Pole connector with the addition of the brake lockout connection on the far end so the yellow, green, brown and white wires should all line up. If leaving the blue brake wire connection open when towing the smaller trailer is a concern. you could wire the...

  • 2012 Honda Goldwing Motorcycle 5-Way Trailer Wiring Recommendation
    The 5-way harness on your 2012 Honda Goldwing is a wiring setup that has separate turn signals from the stop lights. What that means is there is a separate brake light bulb from the turn signal bulb on either side of the trailer. The fifth wire on your bike's trailer connector is not a reverse light circuit so it will be needed. Typical trailer wiring has the stop and turn signals combined so only 4 circuits are needed. You can wire up your trailer the same way and everything would be...

  • Wiring Trailer Lights for 2009 Pontiac Vibe Without Using Converter
    Probably the easiest way to handle this situation would be to use a 5-way connector, part # 20017 for the trailer and part # 20016 for the vehicle end. Use the extra wire for the brake light lead. If the trailer needs to be towed by another vehicle, simply use the 4 to 5 Way Adapter, part # 47515.

  • Replacement 5-Flat Trailer Harness
    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. I have added a link to a video which shows an install of a 5-flat on a boat trailer, as well as a link to a help article on trailer wiring which I strongly...

  • Longer 5-Way Trailer Wiring Connector with Lead
    The longest 5-way connector for a trailer that has built in circuit testers is the part # HM47913 that you referenced. For a 48 inch 5-way and lead we have the part # 20017 but it does not have the circuit testers. We do have a 5-way tester too that you could use with this as part # 20115.

  • 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 to...

  • 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.

    I spoke with my contact at Optronics. The Sealed, Streamline LED Trailer Third Brake Light, # STL80RB, would blink if installed into the trailer light wiring. You will have to hardwire this light differently. You can mount the Sealed, Streamline LED Trailer Third Brake Light, # STL80RB, and then run a wire from it to the trailer side plug. Next, I recommend running a wire from the stop light wire on the brake light switch above the brake pedal, through the firewall, under the vehicle,...

  • 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...

  • 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.

  • Can Base Plates for 2014 Jeep Cherokee be Used for Other Purposes Than Flat Towing
    The Demco Tabless Base Plate Kit # DM9519307 that fits your 4WD 2014 Jeep Cherokee can only be used for flat towing; any other type of use than their intended design is not something that we can recommend doing because it has never been tested for that and could potentially damage your vehicle if used improperly. This particular vehicle does not have a front mounted trailer hitch that will fit or even a grille guard that will fit so a hook in the front is really not a feasible option;...
