  • Where to Find Third Brake Light Circuit for Wiring Up Camper Shell Wiring on 2008 GMC Sierra
    First we need to locate the CHMSL (Center Height Mounted Stop Light) wire on your 2008 GMC Sierra. If you have a 7-way already you will want to check behind that connection for a light blue wire. If you don't have a 7-way prewired you will want to look for a wiring harness up above the spare tire. You may have to push back the wire loom to see the wire but this light blue wire is used for the 3rd brake light for your truck cab. I've included an image for you to see what that harness looks...

  • Which Pin On a 2018 Ford F-150 Trailer Connector Is For Reverse Lights
    Yes, the center pin for the 7-way trailer connector on your 2018 Ford F-150 is for the reverse light circuit. If the vehicle is placed into reverse then the pin will become active and send power to the trailer. I have attached a selection of our backup lights for you below. I recommend the Hot-Line LED Trailer Backup Light Bar part # 328-003-6017W because its's easy to install and has LED bulbs. In order to run the power wire from this light to the trailer connector you can use part # DW07550-1.

  • Recommended Gauge of Wiring for Trailer Lights
    Trailer wiring generally uses 16 gauge wire, part # 16-1-1. However, with a long trailer like yours you may want to go with a larger like 14 gauge # DW07550-1 or even 12 gauge # 12-1-1. Each size is sold by the foot. You will need to have the lights at the rear of the trailer of brakes and turn signals. Also since the trailer will be 10 feet wide you need clearance lights on each side.

  • Recommendation for Submersible LED Backup Lights on a Boat Trailer
    I can help you add reverse lights to your trailer. Yes, It is important to pay attention to DOT compliance when adding lights on your boat trailer. Compliance will be met if you use the Optronics # BUL10CB light as your backup light. The # BUL72CB is purposed for a utility light and will not meet the criteria for reverse lights on the roadway. In order to add reverse lights to your trailer would would need to have a 7-Way on the trailer and a 7-Way on the vehicle. On the vehicle...

  • How to Provide Power to Trailer Reverse Lights
    To connect back up lights you need to have a 7-way trailer connector on both your trailer and tow vehicle. On a 7-way the reverse lights are powered by the center pin. To connect reverse lights to the trailer's 7-way you can use 16 gauge wire # 16-1-1, or 14 gauge # DW07550-1 if you have a longer trailer. Both are sold by the foot. If you need reverse lights a couple of popular options are the Optronics LED Backup Light # BUL10CB for an LED that uses a 2-wire pigtail # A45CB to connect....

  • Can the Goal Zero Adapter Cable 287-98009 be Used to Power a Remote Latch
    The Goal Zero Adapter Cable # 287-98009 has a 6mm input meaning that it is designed so that the power runs to the alligator clips instead of the other way around. This is the opposite of what you are looking for. I can't say if it would work or not in that manner or if it will pop the in line fuse. Traditionally the direction of the power doesn't matter to a fuse but it hasn't been tested for that application so better safe than sorry. If this is for a vehicle and the vehicle has power...

  • Connecting 12 Volt Pump to 7-Round Connector on Tractor
    As long as the 7-round plug on your tractor has 12 volt power, you should be able to wire your 12 volt pump to the connector. You can use a circuit tester like # PTW2993 to test your connector to make sure you have 12 volt power on what should be the center pin location. You will just run the power wire from your pump to a round 7-way like the Pollak HD # PK11702 and then connect it with the connector on your tractor. If you need additional 14 gauge wire, you can use part # DW07550-1.

  • Troubleshooting Optronics Uni-Lite LED Clearance and Side Marker Light Not Coming On with Aux Switch
    I recommend double checking your wiring for the lights. A load resistor will not be needed since the # MCL11CAKB lights are not blinking. A load resistor is designed for use when an LED is hyperflashing when used as a turn signal. You will want to run a wire from the positive terminal on the vehicle battery to the auxiliary switch, then from the switch to the first light, from the first light to the second lights, so on and so forth. The easiest way to connect all of the lights to a...

  • Troubleshooting Right Running Light Not Working Properly on Trailer
    Whenever there are lighting issues it is always best to start off by checking your grounds and connections to make sure that are clean and free of debris. If you are not getting a good signal on your vehicle side connector or if your trailer lights are malfunctioning then I can help you trouble shoot that. If your the running lights on your vehicle are acting up you will need to take it in to a shop to get it looked at as all the information I will be able to provide is that you will...

  • Brake Controller Recommendation for for 2005 Mercedes ML500 for Trailer with Electric Brakes
    Good news! I spoke to my contact at Horizon Global, who makes many of the brake controller brands like Tekonsha or Draw-Tite, and you should be able to use their brake controllers since they operate on the PWM signal (pulse width modulation) instead of on the output voltage signal. The challenge for you will be to find the correct stoplight wire behind the brake pedal. He instead suggested you locate the CHMSL (Center Height Mounted Stop Light) wire to splice into on your 2005 Mercedes...

  • Left Tail Light on Trailer With 5 Wiring Harness is Not Working Properly
    From your picture and your description I would say that your left turn, tail, and back up signals are all run on separate wires instead of being combined like most of our replacement tail lights are. I recommend starting with your tow vehicle by using a Circuit Tester, like part # 40376, to make sure that the 5-Way on your vehicle side is fully functioning. Moving on to your trailer, I would start by using the circuit tester to see which of those wires are not working on the harness...

  • Trailer Lights Go Out When Headlights and Brake Pedal are Applied
    The problem you described sounds like a ground issue. What I recommend doing is running the ground wire for each of the trailer lights (assuming they do not all ground through the mounting hardware) up to the ground used for the 4-way trailer connector. I would then reground the bundle of wires for the lights and connector to a new bare metal spot on the trailer frame using both a self tapping screw like part # FA1131822 and ring terminal like part # DW05762-1. If you need additional wire...

  • Audible Alert Wont Turn Off w/4-Pole Trailer Connected to a 2016 Ford F-350 w/Factory Backup Camera
    It looks like you can turn off the alert on your 2016 Ford F-350 somewhere in the enhanced park aid or park pilot modes. If you were to turn those modes off then presumably the alert would not sound. It looks like you go into the Settings menu, then Vehicle, then camera settings. From there you can go into enhanced park aids. It is also possible that if your smaller trailer has LED lights there may not be enough power draw for the Ford system to turn off the alert automatically. You...

  • Running Wires For Hopkins Backup Camera To Mount On Front Of Vehicle
    In order for you to be able to use the Hopkins Smart Hitch Backup Camera, part # HM50002 as a camera and monitor, you will need to cut the plug off the end and hard wire the system. If you are going to use it for the front I recommend running the red wire to the battery and use a switch. You will need additional wiring like part # DW07550-1 to reach the switch inside of the vehicle. This is sold by the foot. You will also need to secure the white ground wire to a clean bare metal surface. For...

  • Roadmaster Brake-Lite Installation for 2015 Jeep Cherokee With Push Button Start Switch
    If your 2015 Jeep Cherokee has the push button start switch that doesn't start the engine when the brake fuse is removed, the Roadmaster Brake-Lite Relay Kit # RM-88400 needs to be installed in the Normally Closed position. Here are the instructions for that proper installation: Remove the green wire from the kit. If you are using a Roadmaster Even Brake supplemental braking system, set this wire aside to use later. Locate the brake-light-switch wire in your towed car. Remove the brake...

  • Trailer Clearance Lights Stopped Working After Replacing One Clearance Light
    This sounds like a ground issue or possibly faulty wiring. Trailer light grounds and wiring are much more exposed to the elements and trailer suspension is not as good as on a vehicle to it is more susceptible to problems like this. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean...

  • Do Trailer Lights Sparking Create a Short
    Yes, the reason the lights on your trailer are not getting power is because you created a short when the wires touched. You will need to replace the wire that shorted with the wire gauge you were using, likely 16 gauge # 16-1-1, 14 gauge # DW07550-1 or 12 gauge # 12-1-1. You will need to use Heat Shrink Butt Connector - 16-14 Gauge # DW05744-5 or 12-10 Gauge # DW05745-5 and Heat Gun # ALL836717 if you don't have one. I have added a link to a couple of help articles on trailer wiring...
