  • Items Needed to Re-Wire 1970s Vintage Scamp Travel Trailer
  • The 1970s Scamps are really cute vintage trailers and we can certainly help you with your re-wiring project. We have all wiring parts you'll ever need plus a wide range of trailer lights if you need light fixtures too. Our main page for trailer wiring items is linked and this includes many product categories you can just click on. New wiring is most easily installed using a junction box like # 38656, or like # 277-000141 which includes a pre-wired 7-way plug. All brake and light wiring...

  • Yes there is, you would need to install the Curt Trailer Wiring harness part # C59496 on your ambulance and it will convert the separate trailer wiring to a combined signal that would work well on your trailer.

  • Trailer Tail Lights Pulsate When Running Lights Are Activated
  • The issue you are having with your lights pulsating is because of a bad ground. This usually happens when multiple signals are applied at the same time because the increased power draw then becomes too much for the ground to handle. In order to fix this issue I recommend using a junction box like part # 38656. Once you have this installed you can then run the grounds for all of your lights and the trailer connector to the ground terminal inside the junction box, then to a single point on...

  • Can a 7-Way Junction Box Be Used for a 4-Way
  • There's no reason you couldn't use a 7-way junction box like the part # 38656 to install a 4-way. It would be just a matter of wiring up only 4 posts of the junction box on the input and output side of the box instead of 4. With only 4-wires going into and out of the box the rubber grommet would be too big to provide a seal for the wires. You would need to use a sealant like Loctite Urethane Sealant # L0150811 to seal the grommet. I attached an install video for you to check out as well.

  • Parts Needed to Completely Rewire Trailer with 7-Way for Brakes
  • Often times, people will run the wires from a 7-way such as yours to a junction box like part # 38656. From there, they will run the standard wire colors to the trailer lights, brakes and battery. I have attached a photo that shows how this setup works in the junction box. Most molded 7-way pigtails will come wired with the RV style color code. If you ever need to replace your 7-way connector in the future, you could simply open the junction box, remove the connector and wire loom and install...

  • License Plate Bracket Recccommendation For Trailer Hitch Mounted Cargo Carrier
  • The legality of an obscured rear license plate varies from state to state. If you want to heed the letter of the law, the plate can be relocated to the rear of the cargo carrier. We sell quite a few cargo carriers, and to be honest, it is really not that much of an issue. You could zip tie the plate to your carrier, or use a bracket with a light like part # LPL55CB (In most states, the rear license plate is required to be lit after dark). If your vehicle has a trailer connector,...

  • 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...

  • What Size Ring Terminal Will Fit the Hidden Hitch Wiring Junction Box # 38656
  • I pulled the Trailer Wiring Junction Box # 38656, and Ring Terminal # 44-5310A, from our warehouse. The correct ring terminal size that will fit is part # 44-5310A, which is a 3/16 ID terminal for 12-10 gauge wire. I produced a short video showing that the # 44-5310A ring terminal fits on the post of the Junction Box. Also linked is an FAQ on trailer wiring.

  • How to Determine Trailer Wiring Functions to Allow Installation of 6-Way Plug
  • I can help you with your trailer wiring. The first thing to do is to confirm the function carried on each of the trailer's wires/circuits. This is easy enough to do with a spare 12V battery (or the one in your vehicle). What you want to do is connect 12V power to each wire, one at a time. Typically white wires are ground so connect the white wire to the battery negative post. You may be able to rtace the wires and find the one that attaches to the trailer frame as ground. Then connect...

  • Parts Needed to Re-Wire 18 Foot Car Hauler Trailer with 7-Way Connector
  • To re-wire your 18 foot car hauler with electric brakes on one axle, I recommend using a wiring junction box like # 38656 in order to make the connections from the lights and brakes. Then for a 7-way trailer plug, you can use the Hopkins # H20046. This connector has an 8 foot lead. The shorter 6 foot # H20044 or 4 foot # H20043 trailer connectors are also available. I recommend using a circuit tester like # 40376 to determine the functions for any wires that are not known, as just using...

  • Adding a Battery on an Enclosed Trailer to Power Interior Lights
  • The best way to power the interior lights in your trailer is with its own independent battery. You will not want to use the breakaway battery. The breakaway battery is only designed to operate the breakaway and will drain extremely quickly, they're only required by law to operate your brakes for 15 minutes. There's a few ways you can install a battery onto the trailer. One is to connect it to the 12 volt pin on the trailer's 7-way in place of the breakaway battery that is currently...

  • RV has 7 Way and Need to Connect 4 Way for Dolly and 4 Way for Tow Lights to Use at the Same Time
  • I have a solution for you. We do not have any type of Y adapter but I do have the parts available to allow you to connect both 4 wire flat plugs at the same time. I do recommend that you first check to ensure that you will not be drawing too many amps on the circuit by using both the dolly wiring and the tow lights together. You will need the following products: Car and Trailer End Loop, # 9653P Qty 2 Pollack 7-Pole Trailer Connector, # PK12706 Qty 1 First you will start by cutting...

  • Testing Trailer Lights and Electric Brakes without Connecting Trailer to a Vehicle
  • If you have a separate car/truck battery you could apply power to each of the pins on the trailer connector (or the wires directly some point behind the connector) and that should power on whatever is associated with a given pin.

  • Does a Trailer Junction Box Have to be Used when Switching from 4-Way to 7-Way Trailer Connector
  • Junction boxes are great for keeping things organized and for making changing out trailer side connectors and troubleshooting easier. They are not a necessity so you can keep it if you want, it is entirely up to you. If you want to use the junction box, I have linked some videos that might help. The wire colors and the sides of the trailer they are on are actually a little different then what I would expect. Normally the green wire is the right side right turn and brake light wire and...

  • Typical 7-Way Wiring Color Codes
  • The wire loom part # 459075 does not actually have any wire in it, but it sounds like you are curious about the standard trailer 7-way wire colors. There are a couple variations, but for the most part the diagrams I attached show the most common trailer wiring colors.

  • Draw Tite Gooseneck/5th Wheel Connector # 20027 Recommendation on a 1997 Chevy C/K Series Pickup
  • The absolute easiest way to accomplish this task would be to use a Draw-Tite Wiring Adapter, part # 20027. You would simply plug this into the 7-way that is at the rear of you 1997 Chevy Silverado and then run the 7-way end up to the bed and mount it in a location that is easily accessible for your gooseneck. You will probably want to use some zip-ties to secure it in such a way that it will be accessible when not in use and not drag on the ground. You could make the Trailer Wiring...

  • Is a Fuse Necessary When Wiring a 7-way If 12V Wire Already Is Fused
  • If the truck has a 12V power wire dedicated to the trailer wiring that is already fused, you do not need to add an additional fuse. For example, on newer GM trucks, the 12V power wire from the factory tow package is ran to a 40 amp fuse in the fuse box. In this instance, it is not necessary to add an additional fuse. If you have to run a new 12V power wire, then we recommend adding a 40 amp circuit breaker, like # 9510, before the battery. If you would like to let me know the year,...

  • Recommended Wiring And Waterproof Lights For 2000 Ranger 620 VDS Boat Trailer
  • To completely rewire the trailer you will need to start with a 7-way trailer side wiring harness like part # H20044. You will then need a junction box like part # 38656 to attach to the trailer. You will run the # H20044 harness into the junction box and run the wiring for the brakes and lights off of the posts in the junction box. You will need the appropriate size wire for the lights and for brakes if you have them on the trailer. You will want to run 10 gauge wire like part # 10-1-1...

  • What is the Best Size Wire Loom for Bonded 4 Wire and One 12 Gauge Wire
  • I would go with a 3/8 inch diameter, like # 39035. That should provide enough space for the wires and still give good coverage. This loom comes in a 10 foot length. If you needed less of expect that you might have other wiring to run with the existing wires, you can go to a 1/2 inch loom, sold in 1 foot increments, # 459075-1.

  • Junction Box to Improve Wire Connections on a Trailer
  • The junction box # 38656 is for exactly what you're trying to do. It makes the wiring look a lot cleaner and keeps the connections out of the way. You also need some ring terminals to make the connections. I've linked our selection so you can choose the size you need. Another option we carry is part # ET7WK that includes the junction box with a 7-way and all the ring terminals you need.

The chains are sold individually, so you'd need to order two of them. To find cables of the right length and capacity, you might try doing a Google search.

  • 2010 Ford F-150 Brake Controller Says No Trailer Connected with a Trailer Connected
  • When a brake controller says that there is no trailer attached even if there is a trailer attached that means that it is not sensing the brake magnets. This could be because of a problem on the brake output wire such as a severed wire. It could also mean there is dirt or corrosion on/inside the vehicle or trailer side connectors. There are some tests you can do to determine where the problem is. In the truck cab you will need to sever the brake output wire several inches from the back...

  • Can Spectro Trailer Wiring Junction Box Part # 38656 Be Used on Tow Vehicle for Splicing Wiring
  • Yes, the Spectro junction box can be used in your tow vehicle for making wiring connections. This part has a heavy-duty weatherproof plastic housing and includes grommets and cable clamps. You will need to supply two nuts, washers and 1/4-inch bolts of the appropriate length to install the box on your vehicle. I have linked a video showing installation of this part on a trailer frame. The housing measures 3-1/2 x 2-1/4 x 7 inches. In case you need connectors or wire for your splicing...

  • Wiring Electric Brakes to Trailer Without Access to 7-Pin Wiring on Trailer
  • Yes, it doesn't matter which wire is ground and which one is the power wire coming from the brake assemblies. If you have a brake wire on each side of the trailer, you do not have to splice. You can use a brake wire for each side. Since the trailer is aluminum you cannot just ground to the frame because it does not conduct electricity well. The aluminum trailer probably has a hard metal core which is why the manufacturer was able to ground into the frame with screws. You won't be able...

  • Troubleshooting Trailer Brakes that are Always Engaged
  • First of all did this problem just start happening? If the trailer has always worked fine before on the same truck then it's likely a short on the trailer's brake wiring. I would start by cleaning the connector and make sure it's free of any debris or corrosion. Also make sure the breakaway pin is inserted properly. However, it the probem is from the breakaway switch the brakes will only be locked until the breakaway battery dies. If both of these are fine then you need to inspect...
