My trailer has a red, green and white wire. I'm assuming the white wire from the LED is ground and will be fastened to the trailer itself. How should

I believe you should have 3 wires plus ground (white), one for each turn signal(break light) and one common for the normal tailights. Ground white to the trailer or run a direct wire back to the ground in the plug, or both. I wired everything back to the plug, soidered & waterproofed all connections. So far, its held. Good luck.

When you attach the light to whatever you are attaching it to that acts as your ground. So you just need a positive run to the light. You can ground the adapter to the light as well I would think

I just started having a similar problem. Left break light was very dim. Just started happening. Trailer checked out fine. Problem was with the car wiring. Chech your trailer by connecting a 9 volt battery to the connector plug leads.

You will have to install the correct wiring as well, including the power feed to the controller and to the brakes. Keep in mind that this is a time delayed brake controller, which means the longer you have your foot on the brake the more power that is delivered to your trailer brakes.

You shouldnt need the yellow or green wires at all, unless you want to hook the light bar up to your turn signals. You just want to hook it up so you can see all the cool stuff it does right? Just run red wire to positive battery terminal and black wire to negative battery terminal. It should come right on. Use A to turn it on and off, C to change colors, D to change speed and B to change pattern. This light is very cool I promise. Its the best one of the 3 that i have had so far.

From description: For the wire line, black-- main line, yellow-- turn light, white-- reversing light, green--tail light, red--brake light. You only have 4 wires on these LED's or your existing vehicle/trailer wiring? If you're missing wiring on these LED's I'd suggest contacting the Manufacturer. I'll assume you're installing these lights on a vehicle/trailer with the wiring described in your question. 2 wires for turn should be for left and right. One to each of the LED's yellow wires (your existing wiring may vary but typically from vehicle yellow=left, green=right). Same goes for "2for backup" (1 wire to L/R side of the new lights white wire). You should test voltage on your existing wiring to determine which of the "2for brake" wires is tail (lower voltage) and brake (higher voltage to be visible when taillights are on) or add an inline resistor to your existing taillight wire to reduce the taillight signal (green) so the brake light will be visible when both are on. Im not 100% on this but you may be able to simply wire the LED's brake and tail wires together (green/red) if your source varies output voltage via a brake switch or similar. Black-main line I believe is ground connection. Also check that your flashers work correctly (if applicable) as LED's draw very little load and often do odd things to flasher relays. Hope this helps. Good Luck

I don't mean to be a smart aleck, but they control whatever function you hook them up to. I was replacing my old pigtail and the wires in the new cable were a perfect match. I used an ohm meter to run the wires and make sure they went to the same pin on the plug as the old ones, and they did. I just had to do a color for color swap over. I was also replacing a connector box on my trailer an missed a small ground wire connection, that really played havoc with my lights. Nothing was working correctly. Once I re-installed that small ground wire all was good.

extremely easy. One wire to positive side of battery. The Ground is the chassis of trailer, so only one wire to hook up.

Your right, I have purchased several different models of the LED lights for evaluation and none have the yellow wire with the green stripe connected. Not even the 90 to 240 volt version has it connected. The three wire cord is a standard cord used in AC powered devices where the yellow wire with a green tracer is the ground. I assume they had a large stock of this wire and decided to just use it. The lights I have do not have the yellow wire extended inside the case. With out modifying or changing the wire you will need to depend on the mounting for ground if needed. As far as the LED lights, I have been impressed. They have worked very well.

no it wires directly to the battery on the trailer. the hot wire comes with an inline fuse.

Yes. The wire harness supplies vehicle's power to trailer lights (and breaks if your trailer has them--i.e. campers). Working tail lights on trailers are required.

Those are your hot leds an you ground what ever you are powering to the body of the vehicle! You can use existing screws, bolts ext.

Connect the white to ground. Other to a hot wire that works by the ignition switch. They work fine, but would have been nice to have instructions.

When I plug my trailer into a generator it works fine. If you were running the generator directly to the unit them you might have to take some precautions as to the correct wiring....hope that helps.

Standard wiring in an RV is usually the white is ground (-). A typical 12VDC device with a red and black pair, the black is ground (-).Hope that helps!

I wired mine directly to the battery that is mounted to the trailer tongue. Probably could wire it to the 7-pin, but then the tow vehicle would always need to be hooked up to use the jack.

you have to find the wire that runs the day time running lights and connect the red to it. the black wire is the ground wire.
