Expert Answers about Chevrolet Trailer Wiring

• Recommended Replacement Wiring for 1996 Dutchman Duck with Obsolete Wiring Harness
• Your best bet is to re-wire the trailer with a new 4-pole connector to match what is on your vehicle. You can use a junction box like # 38656 to join the existing trailer wiring (4 of the 6 wires, that is) to a new trailer-side 4-pole harness such as # W787268 from Wesbar, which is 8-feet long. You will need ring terminals, 8 of them, such as # 44-5310A. The leads from the trailer and the new harness will be joined in the junction box using the ring terminals. You will want to match the...

• Lighting Requirements for 16-Foot Trailer That Needs New Lights and Wiring

Our main pages for trailer lighting and wiring parts are included too. For a whole new...

• Replacing A 4 Wire Trailer Connector With The Bargman WG54006-043
• The Bargman # WG54006-043, along with any other 7-way trailer connector will have 7 wires inside. Green, red, brown, yellow, blue, black and white. What you are describing with the white, brown, green and yellow wires, sound like the standard 4-pin connections. If your trailer has a 7 way plug with only those 4 wires, it almost sounds like someone may have done a DIY wiring job on this trailer at some point, and wired a 7 pin plug to a 4 wire trailer harness. That being said, you certainly...

• Replacement 4-Way Flat Trailer Wiring Harness For 10' Trailer
• This will depend on your trailer and how you prefer to wire the lighting. For a steel trailer you can use a 20 Ft 4-Way Trailer Wiring Harness # A20WB. This harness only has a 30" ground that will attach to the trailer frame and all the lights will ground to the trailer frame to complete the circuit. The 25 Ft 4-Way Trailer Wiring Harness # A25W2GWB has a ground wire that runs the full length of the frame. With this harness you will not use the frame as a ground circuit so all marker...

• Replacing Trailer Connector Wiring for Rockwood A122 A-Frame Trailer with 6-Pole Square Wiring
• Instead of replacing both the 7-Way blade-style connector as well as the 6-Pole square connectors, # 37995, I recommend using a 7-Way connector and junction box to make the connections for your trailer. This will eliminate the additional, unnecessary connection at the 6-Pole square connectors. The 7-Way connector I recommend is the Hopkins 7-Way Molded Trailer Wire Connector with 6 Foot Lead # H20044. This connector will provide power for left turn and brake signals, right turn and brake...

• Trailer Wiring Harness With Tinned Wire
• While tinned wiring is the norm when it comes to interior wiring on boats, boat trailers see a minimal amount of water compared to the actual boats. They do use a tin coating on the pins that are the parts of a wiring harness like the Wesbar 5-Pole Flat Connector # A40W5B since those are most exposed to moisture, but since the actual wiring is rarely exposed to water I'm guessing that's why they don't go the extra mile when it comes to using that wiring within the harnesses. As far as...

• Recommended Replacement 4-Pole Wishbone Trailer Wiring Harness
• It sounds like your trailer has a special type of 4-pole connector called a wishbone harness, such as 20-foot # A20WB or 35-foot # A35W42B. These wishbone harnesses simply use two brown running light wires to make it easier to wire your trailer's lights. The dual wires mean there is no need to run a jumper wire from one side of the trailer to the other; one wire runs down each side of the trailer frame. You can use butt connectors like # 05731-5 which you can wrap in electrical tape for...

• What Are Functions of Extra Wires on Bayliner Trailer Tail Light Assemblies
• Thank you for including a photo of your 2007 Bayliner trailer's passenger-side taillight. It appears your existing light has extra jumper connections on its ground wire (white), stop/turn wire (green) and taillight wire (brown). This may be provided as a convenience to simplify wiring in other lights on the trailer, especially if the trailer is aluminum which makes it tough to get a good ground. We don't offer lights with this wiring set up. Since the 2-pole connectors are the same as...

• Replacing the Car End of a 7-Way Metal Trailer Connector

You can use the wiring diagram on our Trailer Wiring Diagrams page see link to wire the connector to your vehicles wiring.

• Replacement Trailer Wiring for 2006 Lexus GX470 with Factory Tow Package
• For your 2006 Lexus GX470, it sounds like you are looking for the trailer wiring. You mentioned the factory tow package so it likely had a factory 7-way. If that is the case, then you will simply need the Hopkins Plug-In Simple Vehicle Wiring Harness for Factory Tow Package - 7-Way and 4-Flat Connectors # HM43374 which connects to the factory wiring harness already present near the driver's side frame rail in the rear. This connector has the 4-way wiring connection you will use on the...

• Availability of Circuit Testers for Use When Installing Trailer Wiring in Ford F-150
• Thank you for your purchases from etrailer back in June. You are correct that we do offer trailer wiring kits that come pre-packaged with a basic circuit tester. One such example is the Draw-Tite Wiring Kit # 18252 that fits the 2010 F-150. But no worries! We also offer stand-alone testers like # PTW2993.

• Replacement Powered 4-Wire Trailer Harness for 2010 Kawasaki Vulcan
• It sounds like you're looking for a wiring kit like the 4-Pole Trailer Connector and Installation Kit # C59496. This comes with the 6-wire input and then converts to the 4-wire output like what you mentioned. The black wire is for 12V battery power and then the red wire is that brake wire. You can just cut and splice this harness in to where your current connections are so you don't have multiple spliced connections.

• Replacing Damaged 7-Way on Horse Trailer
• There's more than one accepted way to wire a 7-way, but the most common uses the green wire for right turn/brake, yellow wire for left turn/brake, brown for running lamps, blue for brake output black for 12-volt accessory power to the trailer, white for ground and purple for the reverse light circuit. Because wire colors can vary so greatly, we typically tell folks to wire by function, not by color. An alternative color code is yellow wire for auxiliary or reverse lights, green for running...

• Replacement 5-Way Trailer End For a 2007 Ranger Boat Trailer With 5-Way Flat and 7 Wires
• It sounds like your 5-way is going to have 2 ground and 2 running light wires which run down each side of the trailer. If you only need to replace the connector end I recommend using the Hopkins 5-Way Flat Trailer Connector # HM47913. This connector only has 5 wires but you will simply combine the duplicate wires from your trailer into the single wire on the connector end. The Heat Shrink Connectors # DW05744-5 will help make a weather tight connection.

• Installing Replacement 7-Way Trailer Plug on Trailer with 5 Wires
• We can help you reinstall a working 7-way plug on your trailer. The easiest way to wire in a new 7-way RV-style plug like # H20046 on your trailer is to use a wiring junction box like # 38656. A junction box will allow you to make the wiring connections using ring terminals like # 44-5310A (for 10- and 12-gauge wires) and # DW05702-1 (for 14- and 16-gauge wires). It also makes it easy to replace the plug if it ever becomes damaged or corroded. You'll want to test the wires on the trailer...

• Replacement 4-way Connector For 2018 Shorelandr Boat Trailer With Two Brown and White Wires
• I am happy to help! To replace the 4-way connector on your 2018 Shoreland'r Boat trailer I recommend the Wesbar Wishbone Wiring Harness with 4-Pole Flat Trailer Connector - Trailer End - 18" Long # 002402. The reason your harness has 2 brown wires is one runs down each side of the trailer, instead of having to run a jumper wire between the two sides. It is a little odd that it has two grounds (white wire) but you can connect them together and then connect them to the white wire on the...

• Choosing and Installing a Replacement Peterson 7-Function Square Trailer Tail Light
• The Peterson 7-Function Square Trailer Tail Light # 432400 shown in the linked photo uses press-to-release wire connectors. The arrows in the photo show the lower row of holes that need to be pressed with a pin, nail or similar item to release the wires from the upper holes. If the old light is badly corroded or if the release points do not work you can simply snip off the wires with wire cutters as close as possible to the light's housing in order to keep as much as possible of the trailer...

The regular lighting harness is 40' long while the ground wire is 4' long and the blue wire for the reverse light function is 5' long.
