• Found a Loose White Wire on My Trailer, Where Does It Go
  It sounds like there is a white wire coming from the 4 or 7 way connector on your trailer that is not currently connected to anything; in most cases that is the ground wire, and it should be connected to a paint and corrosion free spot on the frame of the trailer. You'll want to use a ring terminal connector like the # DW05702-1 connected to the ground wire and then connect the terminal to the frame with a screw. You'll want to verify the functions of each wire on your trailer, but if...

• Trailer Lamps Work Fine Until Vehicle Headlights Are Turned On
  You're having a ground problem, what you describe are the classic symptoms. When the vehicle headlights are switched on, the maximum amperage will be drawn through the system which is when the problems show up. There's a few specific areas you'll want to check. 1) Make sure the trailer connector socket on the tow vehicle is grounded to the vehicle frame or chassis, and that the connection is tightly made to metal that isn't rusty. 2) Make certain that the main trailer ground which...

• Trailer Receiving Ground Connection Through Trailer Ball
  You do indeed have a ground problem. You'll want to check all the ground points on your trailer. The trailer connector should be grounded somewhere on the trailer tongue. Make sure this connection is made securely to clean, bare metal. Additionally, each lamp should have its own ground connection, either via its mounting hardware being in direct contact with the trailer frame or by a separate ground wire connected to the frame. Make sure these connections are all secure and not corroded....

• Can the Performance Tool 2.5-Watt Solar Battery Charger be Permanently Mounted Outside
  Yes, I confirmed with my contact at Performance Tool that the 2.5-Watt Solar Battery Charger # PTW2997 can be mounted in a location that will expose it to the elements. I recommend using ring terminals like part # DW05702-1 to ensure that it has a solid connection to your battery. The only warning he said the charger has is to mount it away from explosive gases. so as long as you do that you are good to go!

• Can Ground Wire for Trailer Lights be Connected to Main Ground Wire
  You can connect the ground wire from your light to the main ground circuit on your utility trailer, but we typically recommend using a ring terminal like part # DW05702-1 and matching self-tapping screw # FA1131822 to ground it to your trailer frame as this is typically a better connection. If you are having ground issues then it may be that your ground isn't securely connected to a clean, bare-metal surface. If you make sure the frame is clean before connecting ground then you should be fine.

• Installing HM20048 Molded 7-Way Trailer Connector on Surge Brake Equipped Boat Trailer
  If you scroll to the bottom of the product page of the # HM20048 connector, you can see the color code chart that shows which colored wire carries which function. The yellow wire on the # HM20048 would carry the signal from the reverse lights, assuming that the center pin of the trailer connector is tied into the reverse lamp circuit. Since you're using a surge brake system, you won't need the blue wire as you suspected. If the trailer doesn't have a battery or any accessories that require...

• Where Does Ground Wire On Trailer Taillight Attach
  You'll want to ground that wire to the trailer frame, or to a piece of metal that's securely attached to the trailer frame. I'd recommend installing a ring terminal like # DW05702-1 to the end of the wire and using a self-tapping screw to attach it to the trailer frame or metal that's in direct contact to the trailer frame. I'd recommend sanding the area around where you're going to attach the ring terminal down to bare metal, and installing a star washer between the ring terminal and the...

• New Trailer Lights have 1 Wire and Old Ones Used 2 Wires
  The new lights with the 1 wire ground through the mounting hardware. If you want you could attach a ring terminal such as # DW05702-1 to the ground wire on the trailer and run the hardware through it so the ring terminal is between the light and the trailer frame. You would only have to do this if the trailer has an aluminum frame. The other wire is the power wire.

• Where is Second Wire on Trailer Light Supposed to be Connected to
  If you are installing a light that has 2 wires on your trailer, like the Optronics Rectangular LED Trailer Clearance and Side Marker Light # MCL32AB, then you will want to connect one of the wires to the power wire (sounds like the brown wire no your trailer) and the other will be grounded. Some trailers already have a ground wire that is run to the lights and other times you will need to attach that second wire to a clean, bare metal surface on your trailer using a Ring Terminal, like...

• How to Connect a Clearance Light with a Single Wire to a Trailer with Two Wires
  You can definitely wire a clearance light with a single wire to a trailer that has two wires. The first thing to know is that the two wires from the trailer are not positive and negative. Rather, they are the running light wire and the grounding wire. The running light wire (usually brown or black, but sometimes another color) is the wire that you connect to the wire coming from the light. To do this, use a butt connector like part # DW05744-5. The ground wire (usually white) from your...

• 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 power...

• Can I Use Existing Switch on Ford F-250 to Install Power On/Off of Custom 3rd Brake Light Camera
  Yes. There is no reason that you can't just use the upfitter switch in your Ford F-250 to connect the power of the Custom 3rd Brake Light Camera # 3460006 instead of installing a new switch. I've linked an installation video we did that you can use as a reference, as well.

• Preferred Method of Grounding Trailer Lighting Circuits
  Running a direct ground up to the trailer tongue or junction box would certainly work, but the only time I'd see that as being necessary is if the lamps were connected to a non metallic structure or a metallic structure that wasn't directly connected to the trailer frame. If the lamps aren't connected to a metal structure in direct contact with the trailer frame, you can use a short length of # DW02359-1 wire with a # DW05702-1 ring terminal on each end to serve as a jumper wire that joins...

• 7-Way and Light Kit Recommendation for Boat Trailer
  The cleanest way to install the # HM20048 would be to use a junction box like part # 38656. The junction box is weatherproof to protect the wiring connections from the elements. You'd also need some ring terminals, one 10 gauge # DW05741-1 and four 14 gauge, part # DW05702-1. I've linked you to a video showing the junction box being installed. The part # TLL36RK is a submersible trailer wiring kit that would work well on your trailer as well.

• What is Second Wire on Clearance Light for
  Since clearance lights only carry the running/tail light function, if your clearance light has 2 wires that means 1 would be for power and 1 would be for ground. If you check out the Optronics Light # AL82AB you can see that the black wire is for power and the white is for ground. You can either tie your ground wire into the main ground circuit or you can simply add a ring terminal # DW05702-1 and ground it to the frame on your trailer with a self-tapping screw # FA1131822. The ring terminal...

  It sounds like your current lights with 2 wires ground to the trailer by the mounting hardware.

• Replacing Wiring on Old Livestock Trailer with Electric Brakes
  To replace the wiring in your old livestock trailer and install a 7-Way connector to use with your tow vehicles, I recommend using a 7-Way harness like the Hopkins 7-Way Molded Trailer Wire Connector # H20046. When installing the connector and harness on the trailer, you will want to use a junction box # 38656 and 10 gauge wire # 10-1-1 (sold by the foot), which will help protect the connection points and also give the installation a more professional look. The 10 gauge wire will be needed...
