2002 Ford Windstar - Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • 4 Flat
  • Trailer Hitch Wiring
  • Powered Converter
  • Hopkins

Quickly and easily install a 4-way trailer connector on your Ford Windstar with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in connector - no cutting or splicing
    • Run hot lead to car battery
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Protective connection terminals resist corrosion
  • Comes with dust cap for 4-way flat connector, cable ties, and terminal grease packet for electrical connections
  • 90-Day limited warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Powered Tail Light Converter

A tail light converter is built into this T-connector. This converter is a battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

  • Trailer Hitch for a 2003 Ford Windstar Fits Around and Allows Access to the Spare Tire
    The custom fit receiver hitch you are interested in, part # 13085, will fit around and allow you to access the spare tire. If you'll be towing with your van, you'll need the following parts to complete your towing system: Trailer wiring harness with 4 pin connector # HM40615 for models with a build date before November 2002 or # 36345 for models built after October 2002 Ball mount # C45010 2 inch trailer ball # 63845 1-7/8 inch trailer ball # 19260 I've linked to some install videos for you.

  • Trailer Left Turn Signal Not Working But All Other Lights Work Fine
    You can determine where the fault is by doing a little testing using a circuit tester such as # PTW2993. First disconnect the trailer from the tow vehicle. Then use the circuit tester to test the functions of the vehicle side connector while someone sits in the vehicle and operates the light functions. If the left turn signal does not work at the 4-Way, then test the yellow wire leading into the converter box from the vehicle. If that wire does have the proper signal when the left turn...

  • Wire Functions and Locations on Relay for Trailer Wiring Harness HM40615 on 2003 Ford Windstar
    I spoke with my contact at Hopkins about wiring harness # HM40615. Looking at the relay with the metal tab facing up and pointed away from you the terminals have the following functions: 12 o'clock position = red power wire from converter to relay 3 o'clock = white ground wire 6 o'clock = red power wire out to vehicle battery 9 o'clock = black wire to vehicle left side connectors

  • Trailer Wiring Harness Shows No Power on a 2003 Ford Windstar
    As long as you have the connectors with the green wire plugged into the passengers side and the one with the yellow wire plugged into the drivers side on your 2003 Ford Windstar then it would not matter where the black converter box ends up. You will need to make sure that the white ground wire is attached to a clean bare metal surface with no paint or coating between the ring terminal and the metal surface. Also make sure that the power wire is attached to the positive battery terminal...

  • Are Two Power Wires to Battery Needed to Hookup a 4-Pin and 7-Pin Connector on 2003 Ford Windstar
    Yes, you will need to run separate wiring for both connectors. You will need to install the wiring for the 4-pin connector, part # 118305, with its own power wire to the battery. Then, you will need to install the wiring for the 7-pin connector, part # 30717 with its own power wire. This is done to protect the vehicle power and wiring system. You will want to check your owner manual of your vehicle to check and see when the vehicle was manufactured. If your 2003 Ford Windstar was manufactured...

  • Do I Need a Custom Fit Wiring Harness for 2003 Ford Windstar Trailer Wiring
    If you try to splice a simple 4-way connector to your 2003 Ford Windstar you will not get proper taillight function and will cause electrical problems with the vehicle if you hook up a trailer. At the very least you will blow fuses and you could cause a problem with the vehicles computerized electronics. Your Windstar is equipped with a different system for taillights than most other vehicles and needs a Low Side Switching Converter for the taillights to function properly. The converter...

  • Trailer Lights on When 2003 Ford Windstar Lights are Off
    I have a simple solution to a complicated problem. You are using the wrong converter. Your Windstar uses what is called a low-side wiring system. This means that neutral side of the lighting circuit is turned on and off, instead of the positive or hot side. We do offer the correct wiring harness, part # HM40615.

  • Trailer Wiring Harness Options for a 2003 Ford Windstar
    Hopkins tail light converter # HM48895 is a universal fit item so you can use it on your 2003 Ford Windstar. There are other, custom fit options available though. Check the build-date sticker in the door jamb of your Windstar. If it was built before November 2002 you can use # HM40615. If it was built after October 2002 then you can use # 36345.

  • Trailer Lights Stopped Working on a Trailer Towed by a 2003 Ford Windstar
    Testing for continuity on the ground wire from the converter box or bypassing the ground wire on the converter box will not resolve this issue since the issue is probably one of three problems. There is either a short in the trailer wiring, a short in the converter box on the wiring harness or a short in the wiring on the vehicle. The first step would be to disconnect the trailer and test for power at the 4-way trailer connector on your 2003 Ford Windstar using a circuit tester like part...

  • Parts Needed to Install a P2 Brake Controller in a 2003 Ford Windstar
    There isn't a brake controller harness for a 2003 Ford Windstar so the controller has to be hardwired into the vehicle. If your van currently does not have a trailer connector you will start by adding a 4-Way flat using # 36345 if your van was built after October 2002 or # HM40615 if it was built before November 2002. After the 4-Way is installed, or if the van already has one, you will need to use the 4- and 7-Way installation kit # ETBC7. This provides a 7-Way, retains the 4-Way, and...

  • Recommendations for Wiring Harness on 2002 Ford Windstar and Trailer
    We do have a wiring harness option for you, but the Hopkins Tail Light Converter Kit # HM48895 you referenced is not a compatible fit on your 2002 Ford Windstar. I would recommend the Hopkins # HM40615 that is custom-made for your vehicle. It provides a 4-pole late trailer connector to your Windstar and features quick and easy installation. I have provided links to the instructions for the proper installation of this item as well as a link to a video showing its installation on a 2002...

  • Hitch Recommendation for a 1999 Ford Windstar Towing a Aluminum Boat and Trailer
    The Curt Trailer Hitch Receiver part # 13085 that you referenced has been confirmed to fit your 1999 Ford Windstar. It will work and be compatible with the rear heat and AC lines that are present at the rear of your vehicle. This hitch has towing capacities of 4,000 lbs total trailer weight and 400 lbs tongue weight. If the weight of your boat and trailer are under these figures then this hitch would have the capacity needed. I wasn't able to determine the towing capacities for your vehicle,...

  • Which Wiring Harness Do I Need For My 2003 Ford Windstar?
    Your 2003 Ford Windstar will require the Plug-N-Tow (R) Low-Side Switching Hardwire Kit # 36345 since it was produced after October 2002. Ford switched to a negative power input on these vehicles. The Hopkins Plug-In Simple Vehicle Wiring Harness # HM40615 is only for the Windstar produced before November 2002.

  • Recommended Trailer Wiring Harness for a 2002 Ford Windstar
    Hey Phil, I think I found what you're looking for but unfortunately it looks like the wiring harness has been discontinued since what looks like 2021 which is probably why you can't find the video. Similarly I've found the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM40615 which is available still but there is no install video for it but it's pretty easy to install. All you'll need to do is plug into your vehicle's wiring harness which located...

  • Draw Bar Recommendation for a 2002 Ford Windstar LX
    This Cushioned Ball Mount for 2 inch Hitches - 10-3/4 inch Rise - 12 inch Drop - 7,000 lbs, part # AMSC12 is cushioned in the rise and drop position for stopping and taking off. If you wanted something to make the fit of the draw bar in to your hitch more of a snug fit which would in turn prevent rattling noises. I would recommend the Roadmaster Quiet Hitch for 2 inch Trailer Hitches, part # RM-061. With that being said, in most situations on the 2002 Ford Windstar you would want to...

  • Towing Capacity of a 2000 Ford Windstar and Trailer Hitch and Wiring Recommendations
    Your 2000 Ford Windstar has a gross trailer weight rating of 2,000 pounds unless it has the optional trailer tow package AND 3.8 liter motor. If it has both of those features then it is rated for up to 3,500 pounds. Curt trailer hitch # 13085 itself is rated for 4,000 pounds gross trailer weight so it covers all of the 2000 Ford Windstar models. But you are still limited to whatever the vehicle is rated for (see towing section of the owner's manual for more information) since all of the...

  • Trailer Hitch Recommendation for a 2003 Ford Windstar
    For your 2003 Ford Windstar the Curt hitch part # 13085 is a confirmed fit and has the highest towing capacities of 4,000 lbs total trailer weight and 400 lbs tongue weight. From the research I did on your vehicle it can have towing capacities of between 2,000 and 3,500 lbs depending on how the vehicle is equipped so you would need to check your owners manual for more info. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2...

  • Trailer Hitch Recommendation for a 2001 Ford Windstar
    You might try using a different web browser. Chrome, IE, or Firefox etc. can render videos differently. I attached the video to the right, hopefully it works for you now. For a hitch for your 2001 Ford Windstar the # 75055 that you referenced would be a great choice. For trailer wiring you would want the part # HM40615. For ball mounts I recommend the etrailer Ball Mount Kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag.

  • How Much Ground Clearance On a 2002 Ford Windstar with Curt Trailer Hitch # 13085 Installed
    I can tell you how to measure to determine how much ground clearance you will have with the Curt hitch # 13085 installed on your 2002 Ford Windstar. First, take a look at the installation instructions I have linked for you to see the installation location on the van. If you measure from the bottom of the frame at the rear most attachment point down 6-3/8 inches, that will be where the bottom of the receiver will be. When parked on level ground, measure up from the ground to this point...

  • Lengthening Power Wire on T-1 Vehicle Wiring Harness Part HM40615 for 2002 Ford Windstar
    The wire included with the Hopkins Vehicle Wiring Harness, part # HM40615 is 12 Gauge. You can certainly lengthen the wire running to the battery using the same gauge wire and a crimp connector. We offer the wire by the foot as part # 12-1-1 and heat shrink butt connectors as part # DW05745-5. I've linked to installation instructions for you.

  • Parts Needed To Install a 7-Way Trailer Connector On a 2000 Ford Windstar
    In order to install a 7-way trailer connector on a 2000 Ford Windstar you'll need to start with a 4-way, the Hopkins Vehicle Wiring Harness part # HM40615. Then, you can convert this to a 7-way using the 4 to 7-Way with 4-Way Adapter part # ETBC7 or just the Adapter 4-Pole to 7-Pole and 4-Pole part # 37185 if you won't need trailer brakes. Please note, our products are all designed for US spec vehicles. I would not be aware of any difference if present for Euro spec vehicles.
