Video Transcript for Trailer Wiring Harness Installation - 1995 Buick Le Sabre

Today on this 1995 Buick Le Sabre we are going to install part number 18172 from Tow Ready. On this vehicle, what is nice about the wire harness is it is run down one side, so all you have to do is pull back the cover and get to the wiring harness. What is nice about all the GM products is it is almost color for color match up. It is always a good idea to double check everything. We are going to need a ground to do that with, so just install a ground screw into the sheet metal right here. :24

The first thing we are going to want to check out is the running light circuit. That means we are going to hook up brown to brown, because brown on a four pole wiring harness is going to be running lights also. We will go ahead and put our quick splice on. The left turn on a four pole flat wiring harness is going to be yellow. So we will find yellow, the left turn signal right here. Go ahead and check our right turn signal, the green wire here is on the passenger side of the vehicle too, so it might be the same wire. It is always a good idea to check it to make sure, so we know it is our right turn signal. :59

It is going to be everything from this side which is really nice. What we are going to do next is go ahead and put a ground terminal on our white wire here and ground it to the ground screw we made earlier. All right we will bundle our wire loom up the best we can. With a few simple steps this is a pretty easy install. Put everything back together. This four pole flat will stay in the inside of the vehicle when it is not being used. When you need to use it you can pull it out and shut the trunk on it. The door seal is plenty thick so it will not hurt the wire. Shut the trunk and pull out what you need down to the trailer hitch. That pretty much finished our install of part number 18172 from Tow Ready.

Do you have a question about this Wiring?

  • Lighting Functions and Extension Cable for the E-Z Mount Tow Light Kit
  • The E-Z Mount Tow Light Kit, # EZT20B, provides stop, turn and taillight functions for flat towing. If you need an extension There are several options depending on the length that you need. If 48 inches would be long enough you can use the 48 inch Car and Trailer End Loop, # 18044. If 60 inches is needed use the 60 inch Car and Trailer End Loop, # 18045. If you need a custom length wire you could purchase a 4-Pole Trailer End Connector, # 18004, which is 12 inches long, a 4-Pole Vehicle...

  • Adapting 5 Pin Round Connector on Harley-Davidson to 4-Pole Flat Trailer Connector
  • The extra wire on your 5 pin H/D plug will serve one of two purposes. It is either the brake light signal or a constant 12-volt power feed to the trailer. You can easily determine which case you are dealing with by using a circuit tester like part # 40376 on the plug. Activate the turn signals, running lights and brakes to determine which pin carries which circuit. If the extra pin carries a constant 12-volts, and your trailer does not require any power supply, you could simply construct...

  • Installing 4-Pole/7-Way Trailer Connector on Newmar Motorhome
  • There is not an off-the-shelf adapter that would convert your existing 7-way flat blade to a 7-way and 4-pole, but there are some fairly easy options for adding a 4-pole. You can access the wiring harness leading to the existing 7-way, and tap in a 4-pole harness like part # 18172, which would allow you to use both harnesses simultaneously. A circuit tester like part # 40376 would help identify which circuit serves which lighting function. Another option would be to completely remove...

  • Wiring a Brake Controller on a Ford L-8000 Series Truck
  • You will need to hard wire the trailer brake controller on your 8000 series Ford. The following items will be needed for installation. Brake Controller, I recommend the Prodigy P2 Brake Controller- Proportional, item # 90885, which is very easy to use and adjust with differing loads. This controller is the best controller I have towed with to date. You will also need a 7-Way installation Kit, Item # ETBC7 or 6-Way Installation Kit, Item # ETBC6, depending on which connector you need...

  • Adapting 5 Pin Round Connector on a Trike to 4-Pole Flat Trailer Connector
  • I have some options for you, however, I am not familiar with an adapter to convert a 5 pin round trailer connector to a 4-pole flat trailer connector. Since your trike has a 5 pin trailer connector, the extra wire on your 5 pin connector will serve one of two purposes. It is either the brake light signal or a constant 12-volt power feed to the trailer. You can easily determine which case you are dealing with by using a circuit tester like part # 40376 on the plug.

  • How To Determine if a 2006 Jeep Grand Cherokee has a 7-Way
  • If you look at the back of your 2006 Jeep Grand Cherokee and see a wiring connector that looks like the Tow Ready Wiring harness part # 20135 then you have a 7-way. Another option you could have is a 4-way which would look like part # 18172, or you might not have any connector at all. To add a 4-way you would first want the Tow Ready Wiring harness part # 118394. If you needed to upgrade to a 7-way you would need the 4-Way to 7-Way adapter part # 37185 after installing the #118394. For...

  • Trailer Wiring Recommendation for a 1992 Chevy C/K Series 1500 Pickup Truck
  • It sounds like you have wiring that is connected to a third brake light like on a camper shell. What you will need to add a 4-Way flat trailer wiring connector to your 1992 Chevy C/K 1500 is the Tow Ready Custom Fit Vehicle Wiring, # 118315. This harness just plugs in line with the tail light wiring on the truck, on the driver side rear frame rail near the bumper. I have included a link to the installation details for you. The wiring for a third brake light uses a dedicated brake light...

  • Compatibility of Mag-Flat 4-Pole Magnet # 38095 with Hopkins Endurance Quick Fix 4-Pole # HM48190
  • After testing them together, I found that although the Hopkins Mag-Flat # 38095 is a great item, it is not compatible with the Hopkins Endurance Quick Fix 4-pole Connector, part # HM48190. The connector is physically too large to allow the clasp of the Mag-Flat to close and secure the connector. If you want to use the Mag-Flat mounting magnet, I would recommend using a standard 4-pole vehicle end like part # 18172, which would be compatible with the Mag-Flat. If you like the LED tester...

  • Can a 13-Way European Trailer Connector on a Volkswagen Amarok be Converted to US 4-Way Flat
  • The European 13-Way trailer connector does basically the same thing as the US 7-Way does except that the European version has a separate circuit and pin for every function. here in the states the turn signals and brake lights are combined on each side and there is just one running light circuit. In order to adapt the 13-Way you would need to determine which wires control brake lights, turn signals, and running lights on the 13-Way. Then you would take the left turn signal wire and attach...

  • Brake Controller Installation for 1991 Ford E-350 Van Towing an 18 Foot Trailer
  • A brake controller is definitely a good idea and is the only way to activate electric trailer brakes. For your 1991 Ford E-350 I recommend the Tekonsha P2, # 90885. This is a high rated and economically priced brake controller that gets good reviews. For wiring I have included a wiring from scratch FAQ below. I also included a video showing brake controller installation on a similar vehicle. You basically need three things to wire a brake controller. First is the brake controller...

  • Converting Separate Turn Signals and Brake Lights on a Motor Home to Combined to Use a Light Kit
  • I will be happy to help you out. The separate brake light circuit is going to have to be combined with the turn signals in order to use a light kit with a 4-Pole connector. There is a special converter for this, # RM-732. On the input side you will connect the right turn signal wire to the green lead, the left turn signal wire to the yellow lead, and the brake light wire to the red lead. The converter will properly combine the signals and on the output side you will have green for right...

  • Can the Master Lock Wireless Backup Camera be installed on the Back of a Boat Trailer
  • First, the Master Lock wireless backup camera, # 4843DAT, can transmit 125 feet so the distance from the back of the boat to the truck will not be a problem. You could hardwire the transmitter directly to 12 volt power but it would be on all the time. I recommend hardwiring it into a running light circuit on the trailer so it comes on with the running lights like it is made to do. Make sure any wire connections are water tight by using shrink tubing or liquid electrical tape, # SWC50122....

  • Trailer Wiring Harness Recommendation for a 2004 Pontiac Montana
  • Actually, all you will need to do is install a wiring harness, # 118355, on your 2004 Pontiac Montana. But if you wanted to use those factory wires, because you have separate wires for turn signals and brake lights, you would first need to install a converter. The converter, # RM-732, takes the separate signals and combines them which is what a trailer uses. To wire it up your yellow wire will go to the yellow wire on the converter, green will go to green, white will go to white, and...

  • Using Ford LED Hitch Cover on a 2014 Ford Focus when Flat Towing and When Driving
  • Since you are towing the Focus behind the RV, you would not use wiring harness # 118549 for that purpose. This harness would be used for the Focus to tow a trailer and not to tow the Focus with the motor home. I do understand what you are trying to accomplish though and why you selected that harness; the Ford LED hitch cover # CR-017F has to plug into something! But if you want to use the cover all of the time and not just when flat towing the Focus you will need to have the wiring harness...

  • What Type of Trailer Wiring Should I Install on a 2014 Infiniti QX60
  • I am glad to hear our videos helped you install your trailer hitch. Many people want to do their own work themselves and we like to help as much as we can. There are two common types of trailer connectors, the 4-way flat connector like part # 18172 and a 7-way RV style connector like part # PK11893 (see photo). The type of trailer wiring that you would install on your 2014 Infiniti QX60 will depend on the type of connector on the trailer you will be towing. If you do not have a trailer...

  • It sounds like you have a 5-way male connector on your RV like the part # PK11501 and are looking for a way to adapt it to your trailer's 4-way. You will need to make an adapter for this as one isn't available. You will need the part # PK11502, # 16-4B-1 which is sold by the foot and then a 4-way part # 18172. You will need to test the wires of the 5-way on your RV with a circuit tester like part # 3808 for function and then wire up the 4-way flat as needed. The wire colors of the...

If you are needing a connector for your trailer, Wesbar makes the 4 Pole Flat Connector with Jacketed Cable, # W787264. Your vehicle information states that you have a 2007 Volkswagen Jetta.

  • Adapter for a 6-Way Round on a Harley Davidson Trike to a 4-Way Flat Trailer
  • It does not appear that any of the 6-Way to 4-Way adapters are going to work because of the unique pin out that is on the 6-Way on your 2013 Harley trike. You would essentially need to make an adapter to match the pin out. You will need a trailer side 6-Way, # PK11604, and a vehicle side 4-Way, # 18172, cut to the length you need. Then you just attach the wires in the right place to match the 6-Way you have. On the 4-Way end the white wire is ground, yellow is left turn and stop, green...
