Seemed to work just fine. The little blade may slip down in too far and prevent you from getting the wire pushed in all the way, at first. No big deal. Just pull the blade back a bit, and it'll work. The gel is a little thinner than I anticipated, but not a real problem. 132094

These make it easy to splice wires together. The grease should do a good job keeping water out. I made 5 connections with these, and all connections worked on the first attempt. 122138

These 3M connecters are a lot better than the cheap ones from the parts store. It is worth it to spend the money on these when you rewire your whole trailer. 84782

  • How to Wire the LED Trailer License-Plate Light # LPL55CB
  • You will need to use a quick splice, item # 804C, and splice the black wire from the LED Trailer License-Plate Light, item # LPL55CB, into the tail light wire on your trailer. The tail light wire is normally the brown wire, but you should use a circuit tester, item # 3808 if needed, to be sure you are splicing into the correct wire. You will then need to attach the white wire to ground, usually the trailer frame or the white wire coming from the trailer connector. Once wired the license...

  • Recommendations for Splicing Running Light Wires on a Tear Drop Camping Trailer
  • Instead of using a quick splice connector, I recommend splicing into the wiring using a butt connector and then using some shrink tubing or liquid electrical tape, # SWC50122, to seal the connections from the elements. We have different size butt connectors like # 05732-2 for 12 to 10 gauge wires and # 05731-5 for 16 to 14 gauge wires. You will want to be careful when adding lights to a trailer. If you add too many lights, it could be too much power draw on the tow vehicle electrical...

  • Replacing 5-Pole Trailer Connector with Unusual Number Of Wires on Boat Trailer
  • Are you speaking of a 5-pole flat connector like part # 20017? Your description of the plug itself seems to match, but the number of wires on each pin sounds pretty unusual. I've provided a diagram of the usual wire functions on a 5-pole. As you can see, there's nothing unusual about the right turn, left turn and the two wires for the running lights on the driver's and passenger side of the trailer. Having more than one ground wire or more than one wire for the brake solenoid is...

  • What Do I Need To Equip My 2003 Dodge Ram 1500 Truck With to Pull Trailer That Has Brakes
  • Yes, when hooking your 2003 Dodge Ram 1500 with 4 prong wiring, to a trailer that has brakes, you will need to convert the wiring on your vehicle to a 7-way connector and install a brake controller. To convert your wiring on your Dodge Ram 1500 to a 7-way, I would recommend the Brake Controller 7 & 4 Way Installation Kit, part # ETBC7 to convert your wiring to a 7-way connector and hook up to a brake controller. Part # ETBC7 also has a 4 pole outlet, so you can hook up to trailers using...

  • Recommend a Small 24 Volt LED Light to Use On Electric Scooter
  • A red, 24 volt, LED, panel mounted light that I would recommend is the Optronics 7 Inch Round LED Transit Light, part # STL90R24B. You will be able to mount part # STL90R24B to the rear of your electric wheelchair scooter, but it will need to be wired up. To wire the light to your electric scooter, you would need to run the ground wire to the frame of your scooter or to a nut or bolt. Then, run the power wire into the wiring of the output that you connected the small beeper to. You...

  • Need to Tap into 7-Way on 2004 F-250 To Power Stop, Turn, Tail Lights on Headache Rack
  • Since you need to retain the use of the 7-way at your rear bumper for towing while having the same lighting signals available near the cab for your headache rack, one option to consider is using a 5th wheel harness such as # 41157 from Hopkins. This plug-in harness provides on one end dual round U.S. Car connectors in a Y-arrangement that allow you to tap into your existing 7-Way (while keeping all of its functions active for your tow rig). On the other end of the 8-foot cable is a standard...

  • Can I Hardwire Master Lock Backup Camera part # 4843DAT To Prevent Interference with Light Monitor
  • We have not heard of any backup cameras causing problems with light monitoring systems, but with new models that can change. In order to wire this camera to the car without use of the 4-Way, you will need to hard wire it. There are no connectors available for doing this. You will connect the white wire to a good ground point and connect the brown wire wire to a 12V circuit.

  • How To Connect Blue Wire On Tekonsha Brake Controller On 2004 Dodge Ram With 4-Pole
  • Because your 2004 Dodge Ram was not equipped with the 7-way trailer connector, you will also need the Adapter 4 Pole to 7 Pole and 4 Pole, # 37185, trailer connector. You will need a length of 10 gauge wire, Blue Primary Wire - per foot, # 10-1-1, to run from the blue wire on the Dodge adapter that plugs into the brake controller to the rear of the vehicle connecting to the blue brake output wire on the Adapter 4 Pole to 7 Pole and 4 Pole, # 37185. When attaching the Dodge wiring...

  • Best Method for Attaching Tail Lights to Aftermarket Flat Bed on 2008 Nissan Titan
  • I do not have a source for a plug that would mate with the factory harness for your OEM tail lights. Your best bet will be to use a circuit tester like part # 3808 and test the wires in the rear harness to determine their function. The black wire on the replacement tail light will attach to the running light circuit, and the red wire attaches to the turn signal/brake light circuit. Using quick splices like part # 804C would be the simplest method of making your connections. If you go this...

  • How Could I Activate my 2004 Chevy Colorado Tail Light Functions with Tow Dolly Tail Lights
  • There is a way you could wire a RoadMaster Tow Dolly with Electric Brakes, part # RM-2000-1, to allow you to use the tail light functions of the tow dolly and to activate the tail lights of your 2004 Chevy Colorado while being towed. I spoke with my contact at RoadMaster and he informed me that there is not a kit or harness that you could buy that would allow you to do this, and that you would need a Roadmaster Universal Hy-Power Diode Wiring Kit, part # RM-154, and you would have to...

  • How to Add Reverse Lights to a Trailer That has a 4-Way Connector
  • What you will need to do is upgrade your 4-way to a 5-way. The fifth circuit will carry the reverse light circuit to the reverse lights you install on your trailer. On the trailer you will want to cut off your 4-way and install the part # A25W5B in it's place. The fifth circuit will run to the trailer lights to power them. On your vehicle you will want to install the # 20016. You will remove your current 4-way and wire this on it's place. The fifth blue circuit will run to the reverse...

  • Where to Connect Electric Trailer Brake Controller Red Wire on a 2007 Ford Ranger
  • Sometimes, finding and/or connecting to the correct stop light wire on the brake switch can be difficult. There are other places where you may be able to tap into in order to get the correct wire. If your 2007 Ford Ranger has a third brake light on the cab that only comes on when the brake pedal is pushed then you can tap into that wiring. If your brake light signals are separate from the running lights and turn signals, you could tap into the wiring behind the taillight. The best place,...

  • OEM-Style Trailer Wiring Harness for 2011 Nissan Rogue SV
  • We do offer a custom 4-pole trailer wiring harness for the 2011 Rogue that plugs in at the tail light assemblies, part # 118480 from Tow Ready. This product wires in to your Rogue at a different point than the OEM harness which we do not offer. I have linked an installation video showing the process in a 2011 Rogue. The Tow Ready harness does require a 12V power input to its red wire (made through the included wire and fuse holder). Normally this wiring connection is run up along the...

  • Adding a 2nd Set of Tail Lights to a Keystone Outback 274B
  • We have everything that you will need to make something work, but we do not have a kit that was designed for this specific purpose. The factory tail lights that come on the Keystone Outback 274RB do not appear to be LED and we do not carry an LED version of them, so your second set of tail lights may not match the original set. If I were doing this on my trailer, I would want to choose lights that match the existing tail lights as much as possible. Something like the Optronics Low Profile...

  • How to Power an Interior Truck Cap Light on a 2002 GMC Sierra 4x4
  • You have a number of options to power an interior light on your truck bed cap. You could use the 12 volt power wire going to the trailer connector on your truck as a power source. I recommend installing a switch to turn the light on and off when needed, unless the light comes with a switch. Another option would be to run the wire from the cap light directly to the vehicle battery. Again, I recommend installing a switch if you do not already have one so the light does not stay on all...

  • Wiring 4 to 5-Pole Trailer Connector Adapter onto 2005 Jeep Grand Cherokee
  • The blue wire on the 4-Pole to 5-Pole Trailer Connector Adapter would need to be lengthened and tapped into the circuit that feeds the reverse lights on your Grand Cherokee. Simply locate the reverse lamp assembly, and find the wire feeding the bulb. This is where you would tap in the blue wire. You can use a Scotchlok connector, like part # 804C.

  • You are going to need to track down the reverse light circuit of your 2011 Nissan Murano's taillight circuit, tap into it with a quick splice like the # 804C and then run wire to the center pin of the 7-way. I attached a video that will show you how it is done on a similar vehicle. You will need a circuit tester like part # 3808 to test the wires of your taillight circuits to find the correct one to use.

  • What you will need to do is find the wiring harness that runs to your 1995 GMC Sierra's taillights and then using a circuit tester like part # 3808 test all of those wires till you find one that has voltage when the vehicle is put in reverse. Once you find the correct wire you will then attach the white wire of the # RA960137 to it using a quick splice connector like part # 804C and the light will activate properly when put in reverse.

  • Hardwiring in a Brake Controller to a 2008 Toyota Tundra
  • Since you already have installed a 7-Way and have the light functions working just fine what you will need to do to get the brake signal working is to use installation kit # 5506. You will attach one of the wires from the kit to the back of the 7-Way in the 7 oclock position. Route the wire under the truck and up into the engine compartment. Then you will need to route the wire through the firewall using an existing entry point or by drilling being careful not to drill through anything...

  • Where Does the Purple Wire of the Hopkins Adapter part # 37185 Connect in a Volvo XC90
  • The purple wire of the Adapter 4 Pole to 7 Pole # 37185 that you referenced will need to get run to the reverse light circuit of your 2005 Volvo XC90. We do not have a video on how to make this connection but I can tell you that you will need locate the taillight wiring of your vehicle, find the wires that run to the reverse lights and then find the wire that sees 12 volts when the reverse lights (you'll need a circuit tester like our part # 3808) and run the purple wire to the that circuit...

You would need to use quick splices like part # 804C to connect the wires of this harness to the correct wires of your travel trailer taillight wiring. The brown wires will run to the running light circuit, the green to the right stop/turn, the yellow to left stop/turn and the white to the ground circuit of the trailer. This will give you all of the taillight signals on a 4-way that you would need for...

  • To wire in the Pilot Automotive Hitch Covers # CR-018 to the taillight wiring of your Harley you will need to first cut the 4-way connector off of the cover and then run the white wire to a suitable ground (bike frame), run the brown wire to the running light circuit, and then run either the green or yellow wire to the brake light circuit. The last wire won't be used. This lights of this cover are LED so they won't hardly draw anything so they won't overdraw your taillight wiring. Quick...
