  • Recommended 12V Switches To Replace Interior Light Switches
    i have attached a link to the switched we offer that may work for your light switch. For a single pole/single throw switch for 12V DC systems I recommend part # PK34308. If you prefer a switch with a Red pilot light I recommend part # PK34360. These are rocker design switches. If you want a toggle switch for your lights I recommend part # PK34571.

  • Small Single-Pole Rocker Switch
    I am not 100 percent sure what size you need, but a small option for a single-pole rocker switch is the Pollak Universal-Design Rocker Switch # PK34308. This switch is less than an inch wide (15/16") and just under 1-3/4" tall (1-11/16"). The Single Rocker Switch # 37212525 is another option and is just 1-1/8" tall x 1/2" wide. I have added a link to our entire selection of rocker switches for you to check out as well.

  • What Will Pollak Rocker Switch Fit
    It depends on how big the switches are, as we have no way of knowing the dimensions of your control panel. So you'll simply need to measure, and if the opening is 0.830" wide x 1.450" tall and 0.093", 0.125", or 0.187" thick you can use the Pollak Universal-Design Rocker Switch # PK34308.

  • How to Power Enclosed Trailer Lights Off of 12V Battery
    I can tell you exactly what you'll need to power your enclosed trailer's lights off of an independent 12V battery, though there isn't an adapter. You first need to mount the battery with a battery box for 12V batteries like # TLA7708R, and then use junction box # 38656 to tap into your trailer's 7-way. You will also need ring terminals # 44-5310A, and wire # 12-1-1 to run to each light, and to turn the lights on, a light switch such as the Pollak rocker switch # PK34308 or toggle...

  • Wiring Exterior Trailer Lights to be Powered by Reverse Circuit and On Board Battery
    In order to wire your exterior hi-mount trailer lights so that they are powered by the reverse light circuit on your Ram but can also be powered by the on board battery, you will just need to use a diode like the Roadmaster # RM-790. The output side of the diode will go to your exterior LED lights, while the input side will go to the center pin on your 7-Way and also to your on board battery via a switch like # PK34308. I also recommend adding a circuit breaker like # 9506P before the battery....

  • Parts Needed to Power Interior Lights of Enclosed Trailer
    We can help you mount a 12 volt battery to power the interior lights You will need to start with a battery box to mount the batteries, and I recommend the TorkLift PowerArmor Locking Battery Box # TLA7712R or # TLA7708R. If those aren't the correct size for your batteries, I have added a link below to our entire selection of battery boxes for you as well. You will then tap into your 7-way with Trailer Wiring Junction Box # e99009 and run 12-gauge wire # 12-1-1 to your lights (the junction...

  • Power Options for Utility Lighting on Utility Trailer
    There are a few different ways that you can get power to the LED utility lights on your trailer. The first would be to have a battery directly on your trailer that you could draw power from. This would be the easiest way to get power to your lights. To charge the battery you would need to use a charger like part # CTEK56353 when you have access to a standard wall outlet. One of the perks to using this setup is that you can disconnect your tow vehicle and still use the lights when you...

  • Powering Interior Lights of Enclosed Trailer With 12 Volt Battery
    There is a simpler way than a generator, as this would be difficult, and most generators that have a 12 volt outlet require that only to be used for battery charging. So I recommend a standalone battery on your enclosed trailer, and I'm sure you can find somebody to do it for you, yes. You'll need to utilize local resources though to find someone such as a local handyman possibly or some other individual comfortable with wiring. What you'll do is use a 12 volt battery mounted on the...

  • How to Turn Off Back-Up Alarm of Curt C57100 When Not Towing
    Once the Curt # C57100 is installed, the alarm will sound every time you put the transmission in reverse, regardless of whether or not you're towing at the time. The only way I can think of to defeat the alarm for when you're not towing would be to install a switch like # PK34308 inline on the wire feeding the reverse lamp circuit to the # C57100. You'd need to peel back the tape or wire loom that covers the factory wiring harness the C57100 plugs into. Use a circuit tester like...

  • Parts to Connect Trailer Lights to 12V Trailer Battery
    It is easy to wire your trailer battery to your trailer's lights if that is how you prefer to run them. You might want to add a Solar Charger or two, like # PTW2997, to keep a continuous charge going to the trailer battery. This charger will naturally deliver a varying power output to your battery depending on the level of sunlight hitting the panel so using two in parallel connection to the battery will really help maintain its charge. If you need a 12V power switch to control the lights...

  • How to Wire Furrion Vision S Observation Camera for Better Signal Transmission
    My tech contact at Furrion has seen connectivity issues like you're having with your Furrion Vision S observation camera system # FOS43TASF. He said that late model vehicles and/or trailers that have highly-efficient LED lights may not use wiring heavy enough to fully power the transmitter on the camera. The fix for this is to use a direct battery connection and a manual switch like # PK34308 for delivering operating power to the camera, rather than the clearance light circuit on the trailer.

  • 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...

  • Troubleshooting Lost Power on 7-Way Trailer Connector on 2018 Ram 1500
    I'd start by making sure that your 7 way didn't get disconnected from the US car connector it's plugged into. If a fuse was blown, it would normally only effect the circuit that it's tied to, so I don't believe that would be the cause of your issue. For everything to completely shut off would lead me to believe that something has either become loose or disconnected completely. If that isn't the case, it might be possible that something overloaded the 7 way connector and fried it. You...
