Expert Answers about Tow Ready

  • Parts Needed to Allow Tow Vehicle Battery to Charge Trailer Battery While Driving
  • You may be able to use the existing 12V feed at the back of your truck to charge your trailer battery while driving but you will need to install a battery isolation solenoid to disconnect this line when the tow vehicle is off. Otherwise your trailer battery could drain the battery in the tow vehicle. You will also want to ensure that you are using a wire gauge heavy enough to pass the charging current to the trailer battery; 10-gauge would be the minimum. You can use part # TR118665...

  • Trailer Wiring Has 5-Wires White, Yellow, Green, Yellow/Brown, and Green/Brown
  • On a 4-Way flat trailer wiring harness, white is the ground, brown is running lights, yellow is left turn signal and green is right turn signal. It sounds like your trailer has a wishbone harness. A wishbone harness splits the running light circuit at the connector so you do not have to run a jumper from one side of the trailer to the other side. On a wishbone 4-Way connector the white wire is ground, yellow is left turn signal, yellow/brown is left side running lights, green is right...

  • How to Wire the 7-Way Charge Wire to Trailer Winch Battery and Protect the Vehicle Battery
  • For the best protection of your vehicles battery and wiring we recommend installing a 40 amp circuit breaker, # PK54540, inline on the charging wire going from your vehicle battery back to the trailer connector on your vehicle. If your vehicle has a factory 7-Way connector the charge line will be protected by a fuse in the power distribution box under the hood so adding a circuit breaker would not be needed. If you are concerned about drawing power from the vehicle battery when the vehicle...

  • Why Does my 4-Way Connector Have 2 Wires Ran to One Prong for the Tail Light Circuit
  • It sounds like you need an Optronics wishbone wiring harness, part # A35W42B. This 4-Way has a prong that has two wires that come out of it. The reason some 4-Ways have two wires coming out of one port is because that prong represents the tail light functions for both sides of the trailer. So one wire would run to the tail lights on one side of the trailer, and the other wire would run to the other. I attached a video below that shows this product being installed onto a trailer and...

  • Can I Charge My Trailer Battery Using 7-Way Trailer Connector on Truck
  • You would not be able to charge your battery through the wiring on your 4-way trailer connector. Since your truck has a 7-way connector, you could maintain the power to the battery but not charge it. To begin, you would need to cut off your 4-way trailer connector and install a 7-way connector on the trailer like the Optronics 7-way, part # A7WCB. You would need to connect the appropriate wires. White is ground, Yellow is left turn and brake, Green is right turn and brake, and Black...

  • Best Placement in Truck Bed for Fifth Wheel 7-Way Trailer Connector
  • The best spot to install the Trailer Connector is on the bed sidewall on the drivers side, between the wheel well and the tail gate. We have an installation video showing this Draw-Tite Fifth Wheel and Gooseneck Wiring Harness # 20110 being installed on a 2002 Ford F250. You might want to consider using some dielectric grease, part # 11755 on the connections to provide protection from moisture. If you click the provided link, you can see an install video.

  • Some Trailer Lights Are Not Working But Running Lights and Marker Lights Are Not
  • You are probably on the right track in thinking a grounding issue is at fault. Often if a trailer has a weak or marginal ground connection it will be able to pass enough current for lower current draw lights (such as the turn signals that are not on continuously) but not enough for the always-on running and marker lights. I suggest you recheck the security of the ground connections. You can try sanding off paint (or rust) at the spot where your ground wire ring terminals are attached....

  • Trailer Brake Lights Do Not Work when Headlights Are On
  • It sounds as if there is a weak ground connection somewhere on the trailer. Ground issues normally show up when there is more load on a system. Your situation is a perfect example of that. With the running lights on already drawing power, stepping on the brakes adds even more draw on the system. First, to isolate the issue, disconnect the trailer from the truck. Then use a circuit tester, like # 3808 if you do not already have one, to test the connector on the truck. Have someone run...

  • Troubleshooting Trailer Turn Signals With 1997 Ford F150 With Factory Wiring Harness
  • You can check the mini fuse panel located behind the power distribution box. There should be a 20 amp fuse in location 2 for the trailer tow stop/turn lamps. Also, in the power distribution box, there is a 40 amp fuse in location 16 for trailer tow battery charge and stop/turn lamps. If this fails to correct the problem you can troubleshoot. The best way is to disconnect the truck and trailer and test each one individually. If you happen to have access to another truck or trailer that...

  • Can a 4-Way Trailer Connector be Plugged Into a 5-Way Vehicle End Trailer Connector
  • You will still be able to use the trailer with the 4-Way after installing the 4 to 5-Way adapter, # 20036. First, you could just remove the adapter if you wanted to and then plug in the 4-Way like normal while stowing the adapter in the truck. The extra wire in the adapter what just not be used. Or, you could plug the 4-Way into the 5-Way end of the adapter. The extra pin on the end is for the extra function on the 5-Way, otherwise, the functions are the same for all the other pins....

  • Are Relays Required to Activate the Trailer Wiring Harness on a Nissan Frontier
  • On the Nissan Frontier and other Nissan vehicles, if the vehicle did not come with a factory tow package it will not have a functioning wiring harness even if one, like # 118263, is added. There will be relays that will need to be inserted to make the trailer wiring harness fully functional. If your Nissan did not come with a factory tow package, you would need to use wiring harness # 118525. This harness comes with the relays needed and the wiring required to make everything functional....

  • Connecting a Trailer w/ 7-Way to Vehicle w/ 4-Way Connector
  • You could wire the Tow Ready Adapter 4 Pole to 7 Pole # 30717 and just have the light functions on your tow vehicle without connecting the other wires. But I would be very cautious about not doing so for several reasons. The first reason is safety. The general rule for towing trailers with brakes, is that if the Gross Trailer Weight is half of the Gross Vehicle Weight, it is recommended to use a brake controller and have brakes on the trailer. Not being able to activate the trailer...

  • 6 Prong Square on Jayco Trailer to 4 Prong Flat Wiring Color Scheme
  • The wiring colors codes for the Jayco style 6-Way connector are not readily available. I can tell you that the following colors have worked out on a Jayco trailer before. Yellow - Not determined, Green - tail light, White - ground, Red - left turn and brake, Black - not determined and Brown -right turn and brake The leftover yellow and black wires would be used for auxillary power and backup lighting or trailer brake power, whichever is needed. You would need to use a circuit tester,...

  • 4-Pole to 7-Pole Vehicle End Trailer Connector for Coleman Pop-up Camper
  • I am sorry, we do not have a wiring diagram for this particular part, however we do have a Wiring FAQ that can help. I have included a link to it below. The white wire on the 4-pole connector is not active because the loose white wire overrides it. So the white wire coming off the adapter needs to be grounded. The 4-pole plug on the adapter needs to be plugged into the original 4-pole plug on the vehicle.

  • Should Hitch Ball Angle Be Adjusted Up and Down or Angled to the Rear Using Weight Distribution
  • The hitch ball angle adjustment on weight distribution systems is designed to provide more or less distribution of the tongue weight on your trailer hitch to the trailer and vehicle axles. If you adjust the ball angle farther away from the towing vehicle, you will angle the weight distribution spring bars down toward the ground and that will distribute more weight. Angling the ball forward towards the towing vehicle puts less angle on the spring bars and therefore less weight is distributed. We...

  • Does a Trailer have to be towed Level or Can it be Off Up or Down
  • If the trailer is less than 1 inch off of being perfectly level either up or down then it will be perfectly fine. Having it slightly higher would be better because presumably the tongue weight of the trailer will pull it down a little. You could also look into different ball mounts with different rise or drop specs. I have included a link to our ball mount main page for you. Tongue weight on a trailer is usually 10 to 15 percent of the gross trailer weight. But it can be less on a boat...

  • Wiring US 4-Pole Trailer Connector to For Trailer with European 7-way
  • I am not aware of the existence of an adapter, but one could be easily constructed. You will need to find a vehicle-side socket to receive the plug from your trailer. We do not carry them, so you will need to obtain one locally. You will also need a vehicle to vehicle taillight converter like part # 118158 and a trailer side 4-pole like part # 18004. You would then wire the converter as shown in the diagram I provided. Using this adapter will separate the turn signal back out so that...

  • How to Determine Where the Fuses and Relays of Ford Replacement Harness # 118243 install on F250
  • You will need to locate the vehicles power distribution box and the trailer tow relay block attached to it. This is under the hood on the driver side. You will need to open the cover to access the fuses. The information for where the fuse locations are will be in the owners manual of your vehicle or even if there is a legend on the fuse box cover you can use that. You will be looking for the trailer tow electric brake and trailer tow battery fuse locations. For the relays you will be...

  • No Power To The 12 Volt Terminal On The 7-Way Vehicle End Connector
  • The 12 volt power lead on the 7-Way will be the terminal that supplies power for trailer interior lights, trailer battery charging. If you are looking at the 7-Way on your vehicle the 12 volt power terminal is the #4 (black) pin located at the 1:00 position. It is normally either a black or red wire. See the picture to the right of a typical 7-Way and it will show the terminal locations and what each function is. I am including a video link on how to wire a 7-Way vehicle end connector. If...

  • Wiring Up a Harbor Freight 4-Way Trailer Connector and Trailer Lights
  • Lets start with the trailer connector. I can tell you what the functions are so it will be easy to connect to the lights once we determine their functions. On a 4-Way, you will have one pin that is covered. That is the ground. Right next to it is the running light pin. Then the left turn/brake light pin. And the last pin is right turn and brake lights. Now, on the lights, since the common wire on both sides is red, I am inclined to believe this is the running light wire. What you...

  • How to Figure Weight Capacity When Using a Hitch Extender or Extra Long Ball Mount
  • One thing to note when using a hitch extender like the Hidden Hitch, # 80307, is that the the tongue weight and towing capacity of your trailer hitch will be reduced by 50 percent due to the increased leverage that is placed on your trailer hitch from your trailer. In your situation, even with the towing capacities of your hitch capacities reduced by 50 percent, you are still limited to the 3,500 lbs gross trailer weight capacity and 350 lbs tongue weight capacity of the hitch extender....

  • Adapter to Connect 4-Way on Vehicle to 6-Way Round on Trailer
  • A vehicle end wiring harness using a 4-Way Flat connector should have 3 female plugs and 1 male pin. A matching 4-Way Flat trailer connector would have 3 male pins and 1 female plug like on the Tow Ready Adapter 4-Way Flat to 6-Way Round, part # 30637. The # 30637 adapter is designed to plug into a 4-Way Flat on a vehicle and the 6-Way Round on the other end, with the male pins, will plug into a 6-Way Round on the trailer that has 6 female plugs. I am including a link to a FAQ page...

  • Troubleshooting Right and Left Turn Lights and Brake Lights Not Working on a 2003 Ford F-250 7-Way
  • You have done a great job troubleshooting the problem so far and have isolated the issue to the truck wiring. I have confirmed with my contact at Tekonsha, and another fuse that you might check would be fuse # 6 in the under dash junction box. This is a fuse for the trailer towing light relay. This will be a 20 amp fuse. This sounds like this is the fuse that is most likely causing the issues on your 2003 Ford F-250, since you do not have either brake or turn signals. The # 6 fuse is...

  • Can a European 7-Way Trailer Connector be Converted to a U.S. 4-Way
  • No. The 7-Way end in the # 118709 adapter is made for the North American style of 7-Way round pins. A European 7-Way, see picture, has separate turn signals and brake lights and a circuit for fog lamps. The tail lights are also separate. You would need to fabricate a special adapter to get the 2 to work together. I would need to know which end has the European 7-Way, the vehicle or the trailer. It would also require a semi-permanent change to the connector on the vehicle or possibly...

  • Is a Battery Isolator Needed When Using 7-Way Connector To Charge the Trailer Battery
  • You will need a battery isolator, like Tow Ready Battery Isolation Solenoid, part # TR118665, if you plan on leaving the trailer connected to the truck when the truck is off. If you unplug the 7-Way, the trailer battery cannot drain the truck battery. If you leave them connected, you would need an isolator to keep the trailer from drawing down the truck battery. The isolation solenoid has three connections. If you are looking at the unit with the dome facing up and the 12v sticker right...

The trailer 6-Way will then plug into the 6-Way receptacle on the adapter. You will also need to ground the white wire on the adapter to the vehicle frame at a clean and corrosion free metal surface.
