I ordered 40' of this for re-wiring my 15' trailer (running it down both sides). This wire is solid yet easy to work with, i.e. separating out an individual wire for splicing, bending, snaking inside trailer framing, etc. This wire is color coded with the 4 standard colors for trailer wiring. 9785

Hi, I am sorry to give you a not so good review but I feel I must be honest. When I received my wire it was in a rat nest I spent some time unknotting it and some of the wires were not connected to the bonded 4 wire by at least 11/2 foot. however the shipping was fast. Thank You David S. 131906

  • There is not an industry standard layout for wiring the 4-Way round pin connector, but there is a layout that is most accepted. If you you are looking at the front side of the 4-Way round trailer side plug, the top left prong would be used for right hand turn signal and brake function, the top right pin would be the left side turn signal and brake light function, while the bottom left would be used for the tail light function. The last pin, on the bottom right would be used for the...

  • Complete Wiring for Lights, Electric Brakes and Controller for a 94 GMC 1/2 Ton Truck and Trailer
  • Lets start with your 1994 GMC 1/2 Ton Truck. You will need to start with the # 118315 4-Way connector. Once the 4-Way is installed, see instructions link, you will need the Brake Controller Installation Kit, # ETBC7, and a brake controller. I recommend the P3 Brake Controller, # 90195, which is one of the best controllers we carry. We have detailed instructions for installation of the controller and the wiring kit, see links, and we have installtion videos of a brake controller and wiring...

  • How to Install a 7-Way Trailer Connector to Add a 12 Volt Power Wire to a Trailer
  • It sounds like you are missing a wire for the running lights on your trailer. Trailers that are wired for lights only typically have 4 wires, one for right stop/turn, one for left stop/turn, one for ground and one for running lights. Does your trailer have functioning turn signals, brake lights and running lights? When installing a 7-way trailer connector, you will need to cut off your current trailer connector and you can either connect your trailer wires to a 7-way connector like the...

  • How Do Utility Trailer Lights Wire Up to the Trailer Wiring Harness.

The yellow wire from your harness will run to the left turn signal red wire. The brown wire will also run to the black wire of this light also. I attached an FAQ on trailer wiring for you to check out also.

  • Brake Lights and Tail Lights Do Not Work on Trailer With 4 Wire System
  • On a trailer that uses a 4-Way wiring harness, the brake lights and turn signals are on the same circuit. So it is strange that the brake lights are not working when the turn signals are. There could be a few different issues going on here, so I recommend starting the troubleshooting process from the beginning. First, with the trailer not connected, check the connector on the tow vehicle for signal using a circuit tester like # 3808. This is to make sure that a signal is coming through...

  • 4-Way Trailer Wiring Harness has 5 Wires Coming Out of It
  • It sounds like you have a wishbone harness. A wishbone harness has 4 pins like a regular 4-Way but where the wires come out the running light circuit is split so you do not have to run a jumper wire between tail lights. You cannot always go by color. If the wire that is split is right next to the ground pin (covered pin) then this is what you have, a split running light wishbone harness like # A20WB.

  • What is Needed to Wire Replacement LED Trailer Lights for Separate Turn and Stop Light Functions

The brown wire carries the running light signal for both sides of the trailer and the white wire is the ground. Please refer to the photo attached. In order to separate the turn and brake signals so they can be sent to separate lights you will need a vehicle-to-vehicle...

  • Troubleshooting Running Light Circuit on Trailer
  • The first step in troubleshooting your trailer taillights would be to determine if the problem is on the vehicle, or in the trailer wiring. Start first by using a circuit tester like part # 40376. Turn on the vehicle headlights, and use the tester to check the pin on the trailer connector that carries the running light circuit. If you have a 4-pole connector, test the pin fed by the brown wire. If you have a 7-way, check the pin in the 11:00 position. If you get a signal on that pin, the...

  • Trailer Light Kit for a 10 Foot Trailer
  • Legally a trailer only needs right and left turn signals, brake lights, and running lights. The license plate light will be tied into the running light circuit. On a trailer, the turn signals and brake lights are on the same circuit on each side. So the minimum you will need is 4-wire bonded wire such as # 16-4B-1 that you have referenced. For a trailer side 4-Way you can use # A20WB and you would not need the wire by itself. This is a 20 foot length and the running light circuit is...

  • How to Rewire an Old Cattle Trailer

The colors that you see on the 7-way connector are typical for RV style trailers rather than utility, cargo, or livestock style trailers. The black wire should be connected to the terminal in the 7-way connector labeled black. This is the terminal in the 11 oclock position when you are looking at the back of the trailer connector (see...

  • Typically, the black wire is 12 volt power and the red wire is left turn/brake lights. But you cannot always go by color. If the wiring in question is on the trailer side then there are two ways to determine which color wire does what function. You can physically trace the wires from the connector to where they terminate to discover their functions. Or you could apply power to each wire using a separate 12 volt battery and see what light or function turns on. If the wiring is on the...

The first step that I recommend is to check the connector on the vehicle. If the connector appears to be in good working order and is free of corrosion or road grime, then I would use a circuit tester like the Quickee...

  • How to Power a Separate Clearance Trailer Light

If you want that light to be on only when the running lights are on, then you would not have to run a separate wire. You could simply cut the wire at the 6-way trailer connector and splice it into the running light circuit. If you do not want the light on all the time and you want the ability to turn the light on and off as you please, then...

  • I assume you want to use a 7-way connector, like part # PK12706, on your 12v air compressor to power the compressor using the 7-way trailer connector on your truck. You can use a 7-way trailer connector on your air compressor as long as the wire size for the power wire and ground wire from the compressor are not thicker than the 12 volt power wire and ground wire on your truck. The ground wire and 12 volt power wire on your truck are likely either 10 or 12 gauge wire. If your compressor...

If the brand of your trailer is different then your best bet would be to cut off the 6-way of the trailer and wire up a 4-way to the circuits. For a 4-way you could use a Wesbar 4-Pole Connector # W787264. You will need to determine what the wiring of your trailer is and then wire those circuits to the 4-way accordingly. You could use a 12 volt car battery and run a jumper wire to all of the circuits...
